1 INTRODUCTIONThe Anderson Ratio:Feeder® chemical dosingpumps are a very versatile MODULAR system. The design permits fitting either one pumperassembly or many to each control unit. Unitswith one pumper mounted directly on the watermotor control unit are called “single pumper”units. Systems with one or more pumpersmounted remotely on a manifold are called“multi-pumper” units. The control units can betotally water operated (Series S or SD) orelectronic with microprocessor control anddigital display (Series J and SMC). No matterwhat type of control unit is used, the installation,operation, and maintenance of the pumperassembly is the same. Therefore, this manualaddresses only the pumper modules. Othermanuals address other parts of the system. Youshould have a complete set of manuals for yourspecific system.
Pumpers are of two types, standard and highcapacity. The standard types are made in four(4)capacities and each may have many options,including material of construction, injection point(IPF), and others. Pumper size and options arecoded onto the system model number(s). Referto the examples for explanation of our modelnumbering scheme.
1.1 SINGLE PUMPER UNITSOn single pumper Series S units the modelnumber is stamped into a plate attached to theflat side of the control unit near the top.
1.2 MULTI PUMPER UNITSWith multi-pumper, Series J and Series SMCsystems, the control unit model number is onthe control unit nameplate or model label. Pumper model numbers are stamped into thepumper, on the flat surface below the feedadjusting knob. The two letters on the rightare the serial number code.

The type of pumper, standard or high capacity, isgenerally identified by the chemical fittings andtubing. Standard types use 1/4" I.D. (3/8" O.D.)tubing. High capacity pumpers use ½" I.D.(approx. 3/4" O.D.) Tubing. Capacity sizes aredetermined by the chemical volume pumped perstroke. They are:
PUMPER CAPACITIES (PER STROKE)
STANDARD CAP HIGH CAP
A3 = 3 mL
T4 = 4 mL
A10 or P1 = 10 mL H1 = 10 mL
A20 or P2 = 20 mL H2 = 20 mL
P4 = 40 mL H4 = 40 mL
2 SETUPNote: Each pumper is calibrated under actualoperating conditions at our factory. Occasionallythe dial scale gear will become disengaged inshipment, or by rough handling, requiringrecalibration. Refer to Section 9 for thecalibration procedure.
If you have a multi-pumper installation, youshould assemble the manifold mounting rack andinstall the pumpers on the manifold, use Figure 1as a guide.
If your system has standard pumpers, see Section2.2.
2.1 HIGH CAPACITY PUMPERSSpecial attention is required to obtain maximumperformance from units with remote highcapacity pumpers. These pumpers are similar insize to the standard pumpers, having the samestroke capacities. However, they have different,much larger chemical check valves and injectionfittings. These larger fitting allow the pumpers to
operate twice as fast as the standard pumperswith doubles their effective capacity. Theyare available only with a “universal” typeinjection point fitting. Standard ball poppetsare stainless steel, with ceramic available asan extra cost option. A strainer is furnishedfor the suction tubing. A bulkhead strainer(P/N 12434) is available as an option.
Some people prefer to plumb the suction lineusing rigid PVC pipe. If you will be doingthis, you should use 3/4" or larger pipe. Besure to install a shutoff valve (3-way for drain)and an in-line strainer with plenty of area. Ytype strainers are OK. The strainer shouldhave 5 GPM or greater capacity.
2.1.1 UNPACKINGAll the fittings for each high capacity pumperwill be enclosed in a heavy polyethylene bag.
Page 3 Pumpers
H.E. Anderson Company PH-101 04/04
2.1.2 INSTALLATIONCONSIDERATIONSHigh capacity pumpers are stroking about thirtytimes a minute at their maximum rate. Theymove a lot of chemical at this rate. You must bevery careful to follow recommended installationprocedures. Failure to do this can result inreduced capacity at higher water flows. Refer tothe installation drawing supplied with yoursystem for details and pointer.
The suction, discharge, and injection fittingtubing is supplied in short lengths which areintended to be installed into 3/4"PVC pipe. Referto the parts drawing for an illustration. Use oflonger lengths of tubing or smaller diameter pipecan restrict the chemical flow during the suctionstroke.
Use of stand-pipes connected to the suction inletsas detailed in Figure 16 (p. 16) is very useful.This reduces the effects of suction linerestriction, allows a quick check of chemicallevel in the tank, and, if the stand-pipes arecalibrated, provides a quick check of pumpercalibration and capacity. Standpipes areavailable from H.E. Anderson Company(Accessory P/N 08649). Use of this accessory iscovered in Section 10.1 of this manual. Whenfeeding dangerous or corrosive chemicals such asacids, the drain hole in the bottom of the pumpercylinder assembly (See Figure 2) should beattached to a drain line which empties into aresistant container. An alternative would beplacing a resistant container directly beneath thedrain hole. Do not obstruct the drain hole.
2.1.3 IPF DRAIN TUBESThe injection point fitting (IPF) is the fittingthrough which chemical is injected into the waterpipe.
The high capacity IPF has two two drain fittings.
See Figure 6, page 9, for identification of thesefittings.. The vent is opened by pressing the airrelease knob. This is done only to prime thepumper and to vent air from the discharge line.However, once the air is gone, liquid will comeout the vent (possibly with great force). For thisreason the vent is made to attach a 1/4" I.D. draintube. You may route this tube to a drain, catchcontainer, or even back to the solution containerwhen practical.
The second drain is a leakage drain. Liquid willcome out this drain only when the internaldiaphragm ruptures.
2.2 STANDARD PUMPERSPerform the following steps for each pumper:Install the suction (lower) and discharge (upper)valves in the plastic pump head. Note the arrowsstamped on the valve bodies, and be sure they arepointing up on both valves.
NOTE: When installing the suction valve, there isan exposed ball poppet. Be careful not to lose the

ball when installing the valve.
There should not be an exposed ball in the upperpump head port. (See Figure 2) Install theinjection fitting (3 types available) in the tee onthe downstream side of the feeder. Werecommend that the injection point fitting behigher than the pumper, and that the chemicalline never rise above the injection fitting. Thiswill keep air from being trapped in the chemicaldischarge line. NOTE: Hand tighten these fittingsonly; never use pliers or wrenches on them.
Now, cut a piece of tubing to connect thedischarge valve to the injection fitting.
NOTE: Use only the black stiff tubing orreinforced tubing for the discharge line. Neveruse the flexible clear vinyl tubing on thedischarge side of the pumper. It is not rated fordischarge pressures.
The tubing should be just long enough to reach,but without any sharp bends that might collapseinto a kink.
Place the concentrate tank into position and cutanother piece of tubing to connect from theuniversal suction fitting (foot-valve/strainer) tothe suction valve on the pumper. But do notinstall the universal suction fitting at this time.Here, the clear vinyl tubing may be used whennot feeding acids. This tubing is not suitable foracids.
2.2.1 UNIVERSAL IPF DRAIN TUBESThe universal injection point fitting (IPF) hastwo two drain fittings. See Figure 14, page 12,for identification of these fittings.. The vent isopened by unscrewing the knurled knob (notshown in the drawing. This is done only to primethe pumper and to vent air from the dischargeline. However, once the air is gone, liquid will
come out the vent (possibly with great force). Forthis reason the vent is made to attach a 3/8" O.D.drain tube. You may be route this tube to a drain,catch container, or even back to the solutioncontainer when practical.
The second drain is a leakage drain. Liquid willcome out this drain only when the internaldiaphragm ruptures. You may also attach a tubeto this drain, although it is only a press fit; thereis no retaining nut.
NOTE: Attaching tubes to these drains may beespecially important if you are pumpingdangerous chemicals such as acids.
3 OPERATIONAL START-UP
3.1 INITIAL CHECK-OUTTurn the water on slowly and let all lines andblending tank fill with water. You should begetting intermittent discharges of water from thewaste line(s).
In the following instructions, the model numbersgiven as examples are for a single pumper unit.The examples apply equally to pumpers on multi-pumper units. In each case the option underdiscussion is underlined; asterisks indicate modelnumber entries which may vary. For example, theplain injector option (discharge check valve)shown as ***-*A for a single pumper unit isequivalent to P*-*A for a pumper module.
These instructions should be repeated for eachpumper.
If you have a plain injector (option ***-*A),disconnect the injection tube at the injectionpoint and let it hang loose. If you have a priminginjector (priming valve, option ***-*B), universalinjector (option ***-*C), or old style (square gray)high capacity injector, open the knurled knob two
Page 5 Pumpers
H.E. Anderson Company PH-101 04/04
turns. If you have a new style (dark brown) highcapacity IPF, push the spring-return primingbutton.
Fill a small container with the chemical you willbe feeding and set the pumper dial to 10(maximum feed).
NOTE: Adjust the feed knob only when the unit ismaking a pumping stroke; it will turn mucheasier during that time.
Elevate the container as high as possible. Thisshould allow the pumper to prime itself. As soonas chemical is visible at the end of the dischargeline (or injection fitting drain port) turn off themain water line. Reconnect the discharge line(hand tighten the nut only) or close the knurledknob hand tight.
Now, fill the 400 ml calibration beaker (suppliedwith your unit) to the 400 ml mark. Remove thesuction fitting and immerse the tube into thebeaker. Put the end of the tube near the bottom ofthe beaker, but not so close as to restrict flow.TIP: You may want to use the 400 ml beaker tocalibrate a larger wide mouth container such as aquart jar. Then you can submerge the end of thesuction tube with the suction fitting still attached.
Restart the feeder and allow the pumper to makeone suction stroke, for a #4 size pumper (model**4-** single pumper unit or model P or H4-**pumper); two strokes, for a #2 pumper (**2-**, Por H2-** or A20-**); four strokes for a #1 pumper(**1-** , P or H1-** or A10-**); or ten strokes for aT4 or A3 pumper (**0-** or T4-** or A3-**). Thenremove the suction fitting from the beaker andstop the feeder operation. In each case thepumper should have drawn 40 ml (30 mL for theA3 pumper) from the beaker.
If the amount drawn from the beaker is not
correct you may refer to Section 9 in this manualon pumper calibration.
3.2 START-UPTurn off the water to stop the feeder. Install thefoot- valve/strainer in the solution concentratetank. If installing a bulkhead fitting, install itabout 2" above the bottom of the tank, to preventthe strainer from becoming fouled by sedimentwhich may collect on the bottom.Connect the suction line from strainer to thesuction valve on the pumpers. Set the pumpers tothe number on the dial calculated to give thedesired feed. Fill your concentrate tanks andrestart your feeder. It should now be operational.You may need to check, as done in the initialcheck-out, to be sure the pumpers are properlyprimed.
4 MAINTENANCE ANDSTORAGE
4.1 MAINTENANCECheck the suction and discharge valves forcleanliness, chemical attack, and scale build-up.At some time the elastomer parts(O-rings anddiaphragms) will have to be replaced. Refer toSections 7 and 8 for complete information onservicing these valves.
��������������������������������NEVER TRANSFER THE SUCTION LINE OFA FEEDER PUMPING ACIDS OR STRONGALKALIS TO A CONTAINER OF WATER.THIS CAN CAUSE DANGEROUS HEATGENERATION WHICH MAY DESTROYYOUR PUMP OR CAUSE PERSONALINJURY. ALWAYS USE SAFETYEQUIPMENT WHEN WORKING WITH ACIDSO R S T R O N G C H E M I C A L S .

Figure 3Injection fitting showing scale build-up
When reinstalling these parts, be sure that theball poppets are in the valves and that the arrowspoint upwards. If you have one of the smallerpumpers (model T4-** or A3-**) install thesuction (lower) valve first. then pour somechemical into the pumper before replacing the
discharge valve. This will help the pumper re-prime itself.Check the injection point fittings. The reaction ofchemical being injected with the chemicalsalready present in the water can in some casescause scale to form. This can reduce the capacityor completely stop chemical flow. If scale isfound, clean it off thoroughly and establish aregular schedule for checking the fittings. (SeeFigure 3)
Check to be sure all pumpers are properly primedafter completing these checks and putting thefeeder back into service.
4.2 STORAGEIf a feeder will not be used for a long period,remove it from service. Flush he pumper andchemical check valves with water, or othersuitable cleansing solution, either by pumpingwater through the unit (if not feeding acid) beforeremoving it or by rinsing these parts afterremoval. Tape the he valve openings closedwhile still wet. This will protect the seals andprevent insects from plugging up the openings.
5 PUMPER AND DIAPHRAGMPROBLEMS
A WORD OF CAUTION: Don’t fix it if it isn’tbroken! Do not disassemble the pumper cylinderuntil testing and trouble shooting indicate thatyou need to do so. There is normally very littlemaintenance or service required internally.
The most common problem with pumpers otherthan faulty chemical check valves is ruptureddiaphragms. When a diaphragm ruptures, youwill notice a drainage out the drain hole on thebottom of the cylinder. If the chemical sidediaphragm has ruptured chemical will be drainingfrom the hole. If the water side diaphragm hasruptured water will be draining from the hole.
It is very important that you replace a rupturedchemical side diaphragm immediately. If you donot, the chemical will attack the back side of thewater side diaphragm causing it to fail also. Thespring and other parts in the cylinder can also beaffected. Prompt attention can save addedexpensive repairs. A ruptured water sidediaphragm should also be fixed as soon aspossible, but it is not nearly as critical as thechemical side diaphragm.
If your feeder has a clear acrylic pump head, youwill be able to observe the condition inside thediaphragm chamber. If you have the gray or blackhead, you will have to rely on external checks todetermine problems which might develop insidethe diaphragm chamber. The things that can gowrong in the diaphragm chamber are few, andthey can be easily checked.
Two possible problems in particular need to bementioned. Sometimes the chemical beingpumped will attack the diaphragm or pumper.
This can cause the diaphragm to stick to the
Page 7 Pumpers

inside of the head. When this happens allpumping action will stop. The second problemalso relates to the chemical being fed. Changingchemicals without flushing the head cansometimes cause a chemical reaction within thediaphragm chamber, and wettable powders cansometimes cake up inside the head. This willgradually reduce the capacity. If your unit doesnot appear to be pumping as much as it should,check the calibration. (See Section 9 for thisprocedure.)
6 SERVICING THE PUMPER
In the rear of this manual you should find anexploded view parts drawing for each type ofpumper module shipped with this manual. Youshould refer to the exploded view drawing and toFigure 4, during the following procedures. Thenumbers in parentheses refer to the identificationnumbers in Figure 4.
To service the pumper, first turn off the waterpressure upstream from the unit.
6.1 CHANGING THE CHEMICAL SIDEDIAPHRAGMTo change the chemical side diaphragm (1),Remove the chemical check valves. Use a pan tocatch the chemical which might be spilled whenthe plastic pump head is removed.
NOTE: Use precautions when dangerouschemicals are being pumped; here you shouldremove the chemical check valves and wash thepump head to remove any remaining chemical.
Remove the screws and plastic pump head. Youmay have to insert a thin blade screwdriverseveral places to free the diaphragm from thehead and cylinder. Turn the stroke adjusting knob(3) until the dial reads 7 or less. Now unscrewand remove the diaphragm.
When you install the new diaphragm, coat thethreads of the threaded stud (5) with a graphitelubricant to prevent sticking to the aluminumdiaphragm insert. Screw in the new diaphragmuntil it seats against the water side diaphragm (2).If the holes in the diaphragm do not line up withthe holes in the cylinder (6), unscrew thediaphragm until they line up. Set the dial to 10,align the valve holes in the plastic head so thehead is vertical, and reinstall the plastic head. After changing a diaphragm you should check thecalibration of pumper and recalibrate it ifnecessary. Refer to Section 9 for this procedure.
6.2 CHANGING THE WATER SIDEDIAPHRAGMBefore disassembling the pumper, mark the brassflange and cylinder so you can reassemble themin the same positions. Refer also to the explodedview parts drawing in the rear of the manual forthese procedures.
To change the water side diaphragm (2) firstremove the chemical side diaphragm (Seeprevious heading). Place the small end of thecylinder face down on your work bench. Remove

H.E. Anderson Company PH-101 04/04
all but two screws, which should be oppositeeach other. There is a spring with about thirtypounds force pushing the diaphragm against theflange. Carefully follow the following procedureto remove the flange from the cylinder. Supportthe flange with your hand as the last screws areremoved. This will prevent damage to thethreaded holes and also prevent the pieces fromflying apart.
To reassemble, place the cylinder, large end up,on your workbench. Place the large end of thespring into the cylinder. If you have a lowpressure pumper, place the spring guide (P/N10009), then the spring (P/N 09995) into thecylinder.
Next, lay the water side diaphragm on the flange.Place all the screws through the flange anddiaphragm. Align the marks you made on thecylinder and flange. If you did not mark thepieces, the cylinder has a drain hole which is atthe bottom. Match this drain hole to the bottomof the flange. Place the flange/ diaphragmassembly onto the spring, push the flange anddiaphragm down and start all the screws in theirholes. Screw the screws down evenly; take careto be sure the flange goes into position without“cocking.” Then tighten all screws securely.Replace the chemical side diaphragm (Seeprevious section 6.1).
6.3 STROKE SHAFT SERVICINGTo replace the O-ring shaft seal the flange mustbe removed from the cylinder. Beforedisassembling the pumper, mark the brass flangeand cylinder so you can reassemble them in thesame positions.
Carefully remove the screws from around theedge of the flange. Do not leave the cylinderassembly open after the flange has been removed.Place a weight of at least thirty pounds on the
exposed diaphragm to hold it in the cylinder.This will prevent damage to the chemical sidediaphragm.
Unscrew the screw holding the pad (4) to thestroke shaft (3). You may now unscrew the shaftand remove it from the flange. If the seal wasleaking, inspect the bore in the flange. If the holeis badly damaged, the flange will have to bereplaced. Check the O-ring for tears or nicks.When replacing the O-ring, be very careful whenstretching it over the threads. You may find iteasier to wrap the threads with tape beforesliding the O-ring into position; installing the O-ring; then removing the tape.
Lubricate the O-ring, shaft, and hole with asilicone lubricant (such as Dow Corning #111silicone grease). Reinstall the shaft and replacethe pad. Screw the pad retaining screw in justenough to allow the pad to revolve, but have noend play.
NOTE: Over tightening the screw may cause theshaft to expand, making it difficult or impossibleto adjust the chemical feed. Reassemble thepumper according to the procedure in the lastparagraph in the previous Section 6.2.

7 CHEMICAL CHECK VALVESAND INJECTION FITTINGS FORHIGH CAPACITY PUMPERS
Drawings of the high capacity fittings are shownin Figures 5 and 6. The high capacity valvemodule combines suction and discharge valves
into a single assembly. They operate the sameas our standard valves. The upper and lowercaps will swivel to the most convenient directionfor tubing runs.
The high capacity injection fitting provides thesame functions as our standard universal injector,including check valve and anti-siphon protectionif properly installed and maintained.
High capacity fittings must be installed verticallyoriented with chemical flow upwards.
7.1 MAINTENANCEKeep the fittings clean. If your unit will be shutdown for extended periods they should beflushed with water.
If a valve stops working, do not disassemble.Instead, remove the entire module and immersein mild acid solution for 5-10 minutes.
Rinse and test by suction to the inlet. If it failsthe suction test the valve must be disassembled.Pull the upper retainer clip on both top andbottom pairs. Remove the cap from the top and

the cap/insert combination from the bottom. Userepair kit P/N 12525.
Inspect the ball and O-ring seat. Replace if anydefects are found and reassemble. It helps to coatthe seal O-rings with Dow Corning # 111 silicone
compound if you have some available.Reassemble the module using a slow twistingoption to ease in the O-ring seals.
Replace the clips and test the valve module againusing suction. Remount the valve module to thepumper. Start the pump and open the air vent on
the injection point fitting to ease priming. Closethe vent when chemical appears at the drain vent.
Servicing the injection fitting is similar. But youshould also remove the diaphragm cap and cleanand inspect the diaphragm section.
8 CHEMICAL CHECK VALVESAND INJECTION FITTINGS FORSTANDARD CAPACITYPUMPERS
8.1 SUCTION AND DISCHARGECHECK VALVES (FIGURES 7 & 8)Remove the suction and discharge check valvesfrom the plastic head (1). Be careful unscrewing
the suction (lower) valve. The ball poppet will beloose in the valve body and may easily be lost.Wash the pump head and valves to remove any
remaining chemical. Your valves may be of twotypes, single valves with one ball poppet each, or

double valves with two ball poppets each. Partnumbers for single valves are P/N 06742 suction
valve, and P/N 02857 discharge valve. Partnumbers for double valves are P/N 09812 doublesuction valve, and P/N 09275 double dischargevalve.
The check valves are formed by a ball seating onan O-ring. Refer to the drawings to see how theindividual valves are assembled. Disassemble thevalves by unscrewing. Hold the valves with thestamped arrows pointing up so as not to lose theball poppets. Service the valves one at a time, sothe parts will not become mixed up.
Remove the ball poppet and inspect it for pittingor cracks. It should be clean and free of anydeposit or scale. Wash it again and lay it aside ona clean cloth. Wash the valve parts again,particularly the inside hole and O-ring in thevalve body.
Under a good light, carefully inspect the O-ringseat. It is in a groove about 3/8" from the end ofthe valve body. Do not use a wire brush or anysharp instrument when cleaning or inspecting the
O-ring. It should also be clean, and free of scale.
There should be no visible cracks, tears, or nicks.
If nothing is found, test the valve by replacing theball, and while holding the assembly vertically(arrow up), suck on the inlet (bottom) of thevalve. It should seal tightly. If it does not, removethe ball and gently rub the O-ring with a smallscrewdriver (1/8" blade).
Be sure the blade has no sharp edges. Refer toFigure 10. Rub the O-ring while rotating thevalve body. Replace the ball and test again. If the

ball still does not seal, replace the O- ring.
The O-ring will generally be ruined when it isremoved, so be sure you have a replacement O-ring before removing the old. Use a safety pin orsimilar tool to remove the O-ring. Spear the O-ring as shown in Figure 9, but be careful not topush the point clear through the O-ring. If youdo, the valve body will be ruined.
Carefully pry the O-ring out of the groove. Use asmall screwdriver to lift it out of the body. Washthe body and inspect the groove for scratches.Inspect the O-ring again. Rub the surface withyour finger. If color rubs off, chemical isattacking the O-ring, and you should also inspectthe chemical side diaphragm for chemical attack.Install the new O-ring by inserting it sidewaysinto the hole. Use the screwdriver blade to gentlyplace one side of the O-ring into the groove.
Gently force the O-ring into the groove byrotating the body and gently pushing with thescrewdriver. When the O-ring is in, rub it withthe screwdriver blade to remove any twists in it,as shown in Figure 10. Gently burnish the O-ringwith the blade while you rotate the valve body.
Now replace the ball and test again. You are nowready to reassemble the valve and reinstall it inthe pumper. Be sure the arrows point verticallyupwards when the valve is installed.
8.2 UNIVERSAL SUCTION FITTING(P/N 07288, FIGURE 11)The universal suction fitting (foot-valve/strainer)uses the same type ball poppet and O-ring seat asthe suction and discharge check valves. It isserviced similarly.
8.3 PLAIN INJECTOR (P/N 09838,FIGURE 12) OR PRIMING INJECTOR(P/N 03830, FIGURE 13)Both of these fittings include a ball poppet checkvalve. The priming injector also has a port whichmay be opened to atmosphere for easy priming.The ball and seat should be serviced similarly tothe suction and discharge check valves.
When reassembling the priming injector, screwthe needle in only hand tight. Also be certain thatthe pin is present in the nozzle. If not present, theball will be pushed into the nozzle, preventingthe feeder from working.
8.4 UNIVERSAL INJECTOR (P/N04094, FIGURE 14) OR ANTI-SIPHONVALVE (P/N 07147, FIGURE 15)These two fittings provide fail-safe protectionagainst siphoning. This is done by a spring biaseddiaphragm. The diaphragm is vented toatmospheric pressure, and is necessarily thin anddelicate. In order to get the protection you expectfrom these devices, REGULAR INSPECTIONAND TESTING IS REQUIRED.
The universal injector fitting should permit flowin the direction of the arrow in Figure 14, atpressures of 6-10 psig or greater. It should notpermit chemical flow if suction is applied to theoutlet.
Figure 14Universal IPF, P/N 04094
Page 13 Pumpers
H.E. Anderson Company PH-101 04/04
The anti-siphon valve should permit flow in thedirection of the arrow in Figure 15, at pressuresof 1-2 psig or greater. It should not permitchemical flow if suction is applied to the outlet.The anti-siphon valve does not have any ballpoppets or O-ring seats. The universal injectorincludes a ball poppet check valve. The poppetand seat are exposed by unscrewing the nozzle.The ball and seat should be serviced similarly tothe check valves. When reassembling, be certainthat the pin is present in the nozzle. If notpresent, the ball will be pushed into the nozzle,preventing the feeder from working.
Common failures of these devices occur from thefollowing causes: Insects plugging the vent hole;Chemical spilled into the vent hole, corroding thespring; Chemical residue building up inside,preventing movement of the diaphragm;Chemical attack of the diaphragm; Andmechanical wear.
Remove the screws holding the cover and removethe cover, spring, pad, and diaphragm. Clean andinspect all parts for dirt, corrosion, chemicalattack and wear. Make sure the vent hole in thecover is open. Check the center seat area of thebody for scratches which might prevent thediaphragm from sealing.
Replace parts where necessary and reassemble
the fitting. When reassembling the universalinjector, screw the needle in only hand tight.

9 PUMPER CALIBRATION
If you have the calibration standpipe accessoryinstalled on your pumpers, calibration andchecking is greatly simplified. Section 10.1covers using the calibration standpipe.
9.1 RECOMMENDED METHODYou may check the calibration of your pumpersat any time according to the following simpleprocedure. You may need to temporarily replacethe suction line at the suction valve on thepumper if the foot-valve/strainer has beeninstalled as a bulkhead fitting, or is otherwiseinaccessible. If this is necessary, be careful not toinadvertently drain your concentrate tank.When performing this test you will be insertingand withdrawing the suction line from agraduated cylinder or beaker. For accurate resultsthis must not be done during suction strokes.Therefore, you should always insert or withdrawthe suction line just after the pump has wastedwater.
With the pumper to be tested fully primed andoperational, fill the calibrated beaker with the
chemical you are feeding. Submerge the suctionline in the beaker and let the pumper make one,or possibly several, suction strokes, depending onthe capacity and setting of the pumper. Thenwithdraw the suction line from the beaker andcalculate the amount of solution withdrawn.
Now, calculate the amount of solution whichshould have been withdrawn, according to thefollowing formula:
SW = (C)(NS)(DS)10
Where
SW = the solution withdrawn in mLNS = the number of stroke in testDS = the dial setting of the pumper
And
C = 40 mL for model P4, H4 pumperC = 20 mL for model P2, H2, or A20
pumperC = 10 mL for model P1, H1, or A10
pumperC = 4 mL for model T4 pumperC = 3 mL for model A3 pumper
If the pumper did not withdraw the correctamount of solution, you may calibrate itaccording to this simple procedure. Simply adjustthe stroke adjustment knob until the pumperwithdraws the amount = C ml per stroke, for theappropriate pumper.
Then remove the screw which holds blue dialcover and remove the cover. Carefully lift out thenumbered dial and reposition it in the dial holderwith the number 10 at the top.
Be certain that the teeth on the edge of thenumbered dial mesh with the teeth of the gear ofthe stroke adjustment shaft. If necessary, loosen
��������������������������������THE FOLLOWING PROCEDURES AREAPPLICABLE ONLY WHEN PUMPING MILDCHEMICALS. STRONG ACIDS, OR OTHERSTRONG CHEMICALS CAN BE VERYHAZARDOUS. ALSO, MIXING SUCHCHEMICALS WITH WATER CANGENERATE ENOUGH HEAT TO DAMAGEYOUR FEEDER! WHEN WORKING WITHSUCH CHEMICALS, CAREFULLY MAKEALL CHECKS WITH THE ACTUALCHEMICAL, OBSERVING PROPER SAFETYPRECAUTIONS. (See ALTERNATEC A L I B R A T I O N , S e c t i o n 9 . 2 )
Page 15 Pumpers
H.E. Anderson Company PH-101 04/04
the screw which holds the dial holder to theflange (the screw is located underneath the dialholder, on the side), and reposition the dialholder so the dial meshes properly.
Once the numbered dial is positioned properly,replace the blue dial scale cover.
Carefully line up the line in the window with themark at number 10 and replace the screw whichholds the cover in place. This completes thecalibration procedure. Readjust the pumper to theproper setting.
9.2 ALTERNATE CALIBRATIONMETHODIn some cases it may not be practical to calibratea pumper in the above manner. This would beespecially true when hazardous chemicals arebeing pumped. There is an alternate calibrationmethod which is generally much safer andsimpler, although not as accurate as thepreceding method. With this second method thepumper may be calibrated when in actualoperation. It does not require a graduatedcylinder or any handling of chemicals.
Using this method, you must first turn thepumper completely off. This is done by turningthe control knob clockwise as far as possible.
This should be done with the pump in actualoperation. You will find that the knob turns withgreat difficulty when the pumper is making asuction stroke. When the pumper is making apumping stroke the knob will turn relativelyeasily. Therefore, you should turn the knob onlyduring the pumping strokes, turning it a little at atime, until the knob will turn no farther. If thepump is stroking slowly, you may need only onepumping stroke to turn the pumper completelyoff.
Once this is done, remove the screw which holds
blue dial cover and remove the cover. Carefullylift out the numbered dial and reposition it in thedial holder with the number 0 at the top.
Be certain that the teeth on the edge of thenumbered dial mesh with the teeth of the gear ofthe stroke adjustment shaft. If necessary, loosenthe screw which holds the dial holder to theflange (the screw is located underneath the dialholder, on the side), and reposition the dialholder so the dial gear meshes properly.
Once the numbered dial is positioned properly,replace the blue dial scale cover. Carefully lineup the line in the window with the mark atnumber 0 and replace the screw which holds thecover in place. This completes the calibrationprocedure. Readjust the pumper to the propersetting.

10 ACCESSORIES
10.1 USING THE CALIBRATIONSTANDPIPE, P/N 08649The Calibration standpipe (Anderson P/N 08649)is a very useful accessory for your AndersonRatio:Feeder® injection system. Installation isshown in Figure 16.
There are two purposes for the standpipe. First itprovides a small local source of chemical. Thiswill prevent the suction cycle from being starvedor restricted, even though the main chemicalstorage may be located some distance away,perhaps in another room. It also allows you toeasily check the chemical level. Second, it allows
easy and safe calibration and checking ofpumpers. The standpipe has a calibrated slidingscale. You can move this scale so that the 0 markat the top is at the top of the liquid level in thestandpipe. Then close the ball valve. When thepump makes its next suction stroke the amount ofchemical withdrawn can be read on the calibratedscale. This will allow you to set or verify propercalibration. You must then open the valve toresume normal operation.
Design is compatible with our standard capacity(3/8" O.D. tubing) or high capacity (3/4" O.D.tubing) systems.

Pilot Valve and Manifold Manual forRatio:Feeder® Chemical metering pumps.
Overview. Pilot Valve.The Pilot Valve is a remote control largecapacity three way valve. This valve is pilotoperated, that is, pressure from the inlet portis used to switch the valve. In some designs,an external pressure signal is used to switchthe valve. This can be either gas or fluidpressure.
The Pilot Valve is used to control themodular pumpers that inject the chemicaladditive into the water line. The pumpers aresingle acting hydraulic (or pneumatic)cylinders. The pressure to power thesecylinders is drawn from the water line, anexternal source such as an air compressor, or acompressed gas storage cylinder. After thepressure is used to inject the chemical, it mustbe exhausted to a drain or container at zeropressure. Because the pumpers operate veryfast at times and because more than onepumper can be used for various reasons, thepilot valve must switch rapidly and have arelatively large flow capacity. The pumpersare single acting so the pilot valve must be athree way type. A three way valve has threeports or connections. A pressure port (inlet),an exhaust port (outlet), and a common(cylinder or pumper) port. The action of thevalve alternately connects the inlet to thecommon or the outlet to the common. Whenthe ‘inlet’ is connected to the ‘common’, the
pumper ‘pumps’ or injects a measured dose ofchemical into the water line. When the valveswitches and connects the ‘outlet’ to the‘common’, a suction cycle occurs. The fluid orgas used to power the pumping cycle isexhausted or wasted and a new measureddose of chemical is drawn into the pumper tobe ready for the next full cycle.
There are two types of pilot valves, twodesigns, three brands, and three sizes. Thefirst type is non-electric, external signalswitching. The second type is electric solenoidoperated, internal pressure signal switching.The first design uses a diaphragm operator.The second uses a piston operator. The threebrands are; Anderson (type A),Honeywell(type S), and Bürkert (type B). The three sizesare (as determined by the thread size of theinput pressure connection); 3/8" NPT, 1/2"NPT, and 3/4" NPT. The model number ofthe Ratio:Feeder® does not identify thevalve. You should identify the valve and makea note in your owners manual for use whenordering parts or requesting help withtroubleshooting.
The main connections to the three wayvalves are as follows.
Standard port designations: Inlet; ‘P’ or ‘1’.Common; ‘A/B’ or ‘2’. Outlet; ‘R’ or ‘3’ or ‘E’.
Identifying the valve brand.The Anderson brand housing is a cube. It hasa small threaded connection for a pressuregauge in addition to the main connections.
The Honeywell brand has a forged body andthe inlet and outlet connections are side by
side opposite from the common port. Thesolenoid housing if used, is generally round.
The Bürkert brand has the three mainconnections on three different faces of thehousing. The solenoid if used, is rectangular.
PV-10 12/99 1 H.E. Anderson Co.
All brands can be either solenoid or externalpressure controlled.
The pilot valve requires a minimum pressureto operate properly. The minimum operatingpressure for the Ratio:Feeder® is 15 psig. Thisis greater than that required for the pilot
valve so we will refer to the minimumpressure requirement as 15 psig for the wholesystem.
Please turn to the section covering the valveyou have. The Manifold section follows thepilot valve section.
Type A (Anderson) Valves.Diaphragm operator, poppet seal, externalpressure or solenoid operated.
Solenoid operated valves com with coilcoltages of 12 VDC & 24 VAC.
Two sizes; ¾" manifold multiple pumper and½" single pumper.
Normal operation, fast ‘crisp’ switching. Asmall very short discharge is typical whenswitching to the ‘on’ or inlet connected to thecommon port state. A larger more distinctdischarge is noted when switching to the ‘off’state. The volume of the waste will beproportional to the size and number ofpumpers attached to the valve. The wastecycles frequency is determined by the waterflow rate in the main line. The valve shouldnever waste continuously.
Detail procedures
Diaphragm replacement. Remove pressurefrom valve. Remove the diaphragm cover part18309 or 18310. Remove opposite cover part18298. Un-stick diaphragm from valve body.Using suitable tools, remove the nuts (P/N18498) from each end of the poppet shaft P/N18343. DO NOT HOLD DIAPHRAGMwhile removing or tightening nuts. Removeand inspect poppets and diaphragm. Replaceif necessary. Install diaphragm first byassembling all parts onto poppet shaftdiaphragm end. Tighten nut by holding shaftwith locking pliers or placing in vise.Diaphragm is a three piece assembly. Theblack ‘rubber’ part with three holes installsaway from the nut. As nut is tightened, the
parts may rotate with respect to one another.Observe how far the parts rotate by observingthe small hole near the edge of the blackdiaphragms. Now loosen the nut andpre-position the parts the other way. Tightenthe nut and the small holes should be inalignment just as the nut becomes tight. Nowplace this assembly into the valve body andassemble the remaining parts onto the otherend of the poppet shaft. Tighten the nut byholding the opposite nut with a suitable tool(socket). Now position the diaphragm so thatthe small hole near the edge is in alignmentwith the hole in the valve body. Replace thecover assembly to seal and hold thediaphragms in the proper position. Replacethe opposite end cover. Place the completevalve back in service and test.

Condition Probable Cause Remedy
Valve doesnot switch
1. No signal. 1. Not a fault of valve. Fix signal.
2. Insufficientpressure.
2. Minimum pressure required for system is 15psig. Also if using pressure from an externalsource to switch the valve, the pressureshould be equal to or preferably greaterthan the pressure in the water line.
3. Dirt in valve orpilot circuit.
3. Sluggish or slow operation can be caused bydirt in the pilot circuit. If solenoid is used,remove the small tube from the end of thesolenoid to the valve body. Blowcompressed air into the small tube. Removethe solenoid. Remove the center parts fromthe coil by pushing on the tube barb. Cleanall parts. Both stainless pieces remove fromthe plastic carrier. Clean orifices. Replaceall parts.
4. Broken diaphragmoperator.
4. Valve follows signal. Be sure signal iscorrect.
Excessive orcontinuouswaste
5. Insufficientpressure.
5. Minimum system pressure is 15 psig.
6. Broken diaphragm. 6. Replace diaphragm, see detail repairprocedures.
7. Damaged poppetand/or seat.
7. Remove diaphragm and poppet shaft.Inspect poppets and seat area in valve body.If seat is damaged valve cannot be repairedin the field. Contact factory.
“Groaning” orchattering
8. Valve switching toorapidly.
8. Broken diaphragm. Replace, see detailprocedures. Ocassionally, low pressure ordirt in the pilot circuit can cause thesesymptoms. See remedy three above.
Type S (Honeywell)Diaphragm operator, poppet seal, externalpressure and electric solenoid operated.
Coil Voltages; 12 VDC, 24, 120, 240 VAC.
Three sizes; 3/8", 1/2", and 3/4"
Rapid operation switching, no sliding seals.Long life and no scheduled maintenance.
Normal operation is indicated by ‘crisp’switching, normally silent, and with a smallshort waste discharge when switching to the‘on’ or ‘inlet’ connected to the ‘common’state. If solenoid operated, the solenoid will beenergized to produce the ‘on’ state. The offstate, ‘outlet’ connected to the ‘common’, willbe noticed by a larger discharge of pressure(water or air). The volume of waste dischargewill be proportional to the size and number ofattached pumpers. There should never be acontinuous waste.
Replacing the Diaphragm.
Remove large and small covers. Separatediaphragm from valve body. Remove nut fromcenter of diaphragm, hold opposite nut, notdiaphragm when removing. Install newdiaphragm assembly so black diaphragm withthree holes is in furthest into body. Tightennut to hold diaphragm onto poppet shaft sothat small holes near outer edge of blackdiaphragms are aligned. DO NOT HOLDDIAPHRAGMS WHILE TIGHTENINGNUTS. DONOT ENGAGE THE SMALLTUBE INTO THE DIAPHRAGMS TO
KEEP THEM IN ALIGNMENT. Tightennut, see how far diaphragms moved. Loosennut, pre-position diaphragms the other way sothat as nut is tightened, the diaphragms willbe in their correct position as the nut becomestight. Insert diaphragm poppet shaft ass’y intobody. DO NOT ENGAGE TUBE INTOSMALL HOLES YET! Now installother side poppet and nut. After both nuts aretight, engage the diaphragms onto the smalltube near the edge. Do not place thediaphragms into any torque stress. Nowreplace the covers. It helps if the screwthreads are coated with an anti-siezelubricant.

Type B (Bürkert) Valves.Piston operator, external signal and electricsolenoid switched, adjustable orifice, manualoperation button. Two sizes; 1/2" and 3/4".
Coil voltages: 12 VDC; 12, 24, 120, and 240VAC.
Normal operation is a ‘crisp’ switching to the‘on’ state (inlet connected to the common). Aslight amount of water or air will be exhaustedduring the transition from ‘off’ to ‘on’. If wateris used, the amount of waste will be about 50ml for the 1/2" valve and 75ml for the 3/4"valve. There should never be a continuouswaste discharge. The normal discharge on thewaste cycle will be proportional to the sizeand number of attached pumpers.
Troubleshooting.Repair procedures. To remove solenoidarmature remove solenoid and turn upsidedown. Remove actuator seal and backupplate. Note small spring pushing againstarmature lever. Place cloth over lever to catchspring and move lever slightly towards springand pull up and out of coil. Find spring incloth and save. Clean coil and manualoperator button with suitable solvent,WD40® can be used if wiped out aftercleaning. Insert tool you have fashioned from
sheet metal or use a metal nail file the sameapproximate width as lever down into the coiland compress the button spring towards themanual operator button. Now insert the leverbetween the nail file and the coil housing andslide it into position. As it moves intoposition, it will compress the spring out of theway. Now remove the nail file and replace thespring near the exposed end of the lever.
Check for proper operation of the lever,depress the manual button and lever shouldmove. Replace the plate and actuator seal andreassemble the coil to the valve.

Valve doesnot switch
1. No pressure signal 1. Not a fault of valve. Fix signal.
2. No pressure in line. 2. Pilot operated valves do not work unlessmain line is pressurized.
3. Manual operatordoes not produceany action.
3. Check armature in solenoid or externaloperator pivot arm P/N 05067. If lever isbroken, replace. On solenoid types, entiresolenoid must be replaced. Orifices may beout of adjustment. “P” side startingadjustment is 2 turns in from flush. “R” sideis 1 1/4 turns in from flush. Dirt or trashmay be preventing piston operator frommoving. Remove solenoid or valveoperator. Clean area in and around pistonby flushing with water. Move piston andflush again. Re-assemble and test. If valvestill does not work, disassemble valve andrepair or replace piston ring and seals andsleeve.
Valve leaks
4. Excessive wastefrom exhaust.
4.Valve not switching completely. Clean as in3 above. Be sure you have 15 psig minimumpressure. Damaged orifice seat. Cannot berepaired in the field.
5. Small continuousleak.
5.Damaged orifice seat. Disassemble andinspect. Cannot be repaired in the field.
6. Leak from or nearsolenoid.
