GENERAL DESCRIPTION

BlackStone pumps are equipped with a singlecontrol for pump output.

Flow range is continuously adjustable from 0to 100% of the maximum capacity through agraded dial on the front of the pumps.

Seven models are available, each with a dif-ferent dosing capacity:

BL 20 18.3 lph (4.8 gph) @ 0.5 bar (7.4 psi)

BL 15 15.2 lph (4.0 gph)@ 1 bar (14.5 psi)

BL 10 10.8 lph (2.9 gph) @ 3 bar (43.5 psi)

BL 7 7.6 lph (2.0 gph) @ 3 bar (43.5 psi)

BL 5 5.0 lph (1.3 gph) @ 7 bar (101.5 psi)

BL 3 2.9 lph (0.8 gph) @ 8 bar (116 psi)

BL 1.5 1.5 lph (0.4 gph) @13 bar (188.5 psi)

High quality materials

To provide the maximum protection for partsthat are in contact with aggressive chemi-cals, diaphragms, hose connectors and pumpheads are produced using materials as PVDFand PTFE.

Always store chemicals in safe, out of reachplaces. Follow the directions for use witheach chemical. Do not assume chemicalsare the same because they look alike. HannaInstruments cannot be held responsible forthe misuse of chemicals or the pump.

Always wear protective clothing (gloves andsafety glasses) when working near chemicaldosing pumps. When pumping chemicals,make sure all tubes are securely attached tothe fittings. It is recommended that tubing isshielded to prevent possible injury in caseof rupture or accidental damage.

Avoid using a pipe wrench or pliers on plas-tic parts and connectors. These are besttightened with an open end or crescentwrench. Avoid overtightening these partsas this could cause damage to the seatsand threads.

If a hose is used, it should be securelyfastened to columns, walls, braces, etc. Thiswill ensure that the hose connection will re-main tight and leak free. Shield the hosefrom direct sunlight. Sunlight can cause anautocatalytic reaction with some chemicalsand weaken the hose walls.

The arrow on the pump head indicates thedirection of chemical flow and should al-ways point upwards (vertically). Never posi-tion the pump horizontally with suction anddischarge valves horizontal. Locate the pumpin an area out of the reach of children andpets.

All pumps undergo stringent tests to ensurethat they comply with their stated specifica-tions and are calibrated at the maximumrated pressure.

The ball valves are constructed in glass. Thebody is made of fiber-reinforced polypropy-lene for strength and durability.

Reliability through simplicity

All BlackStone pumps use the positive dis-placement solenoid method of pumping. Thismethod has fewer moving parts than a stan-dard motor-driven pump, and does not havethe mechanical failures associated with con-ventional pumps.BlackStone's Positive Displacement designhas several distinct advantages over othertypes of mechanical designs:• It is more accurate. Each stroke of thepiston is precisely the same as the strokebefore it ... and the stroke after it.

• Positive displacement allows for easier self-priming.

• Pumping pressure is as high as 12 bar(176 psi). This allows you to install yourpump in the widest variety of tank-to-tankand tank-to-in-line applications.

• High accuracy and repeatability. A wire-wound potentiometer and solid state elec-tronics are combined to achieve greaterprecision and control.

Easy installation

Designed with mounting holes in the base aswell as rear panel, BlackStone pumps can beinstalled on a wall as well as directly on topof tanks and drums.There is no need for additional hardware.All the controls and pump assemblies areconveniently located on the front of the unit.If the operator must access the pump heador control panel for any reason, there is noneed to dismount the unit.

Power Requirements

BlackStone pumps are designed to operateto specifications within the following voltageranges:

100 - 130 Volts for -1 models

200 - 240 Volts for -2 models

To ensure maximum performance, check thevoltage at the point of supply to verify that itis sufficient. It is recommended that you in-stall a 1 Amp circuit breaker between thepump and the power supply. This will giveadditional protection to the internal circuitand provide a convenient way to disconnectthe power supply prior to servicing the pump,if needed.

Injection Point

• Choose an injection point that allows youto mount the injection valve assembly ver-tically.

• The spring in the injection valve assembly(HI 721004) adds approximately 1.5 bar ofback pressure. If pumping into a high backpressure, the spring should be removed.

Other Considerations

• If you are mounting the system to a wall,column, etc., be sure it is strong enoughto support the weight of the entire system.

• The ambient temperature of the pump,when in operation, should be between 0and 50°C (32 to 122°F) and should beprotected from direct exposure to outdoorelements (direct sunlight, rain, extreme tem-peratures, high humidity, etc.).

• Generally speaking, the shorter the suctiondistance, the more efficient the pump oper-ates.

INSTALLATION

Materials Needed

• LDPE hose (7 meter / 22 feet) (included)or other type of tubing (PTFE, for example)more suitable for a specific application (op-tional)

Optional Accessories• 4 each, ceramic weights (HI 721008)

• 1 each, foot valve assembly (HI 721005)

• 1 each, injection valve assembly (HI 721004)

Location

A suitable location should:• be near to a power source• be conveniently close to the injection point• allow easy access to the flow rate controland pipe or hose connections

• be no more than 1.5 meters (5 feet) abovethe operating position of the suction valveassembly.

Dimensions for Installation

BlackStone pumps are designed for perma-nent installation.

The pump can be mounted directly on a wallor tank.

Page 8: Manual Bomba Dosificadora

1514

It is recommended that the system be con-nected to a power line/leg equipped with acircuit breaker of 1 Amp.

Permanent Connection using 3/8"PVC pipe

All piping for thepump feed and dis-charge should beplumbed to the loca-tion of the pump.

The threads on bothvalve assemblies al-low the use of stan-dard 3/8" (European)pipe fittings for per-manent pipe connec-tions.

The foot valve as-sembly (HI 721005)should always hangvertically and not layhorizontal on thebottom of the tankor drum.

A vertical assemblywill ensure that thevalve is positionedproperly and preventloss of prime.

For the U.S. standard installations, use PVCadapters to connect the suction and dis-charge valves to the PVC pipe.

• The pump should be placed in a conven-tional location that will allow easy accessto the control and connections. It should beplaced so that regular visual inspections ofthe connections and hoses are facilitated.

Vertical Surface Mounting

Once you have selected the best installationsite, simply screw or bolt the unit into a wallor mounting panel above the chemical feedtank.

The 4 mounting screw holes on the pumpwill accommodate up to a 5 m m (3/16")screw or bolt (remember to use heavy screwsor bolts to secure the system).

Be sure you do not over tighten and causeexcessive stress on the mounting holes.

Electrical Connections

Note: All cables must be according to localelectrical codes.

For safety of the users, the pump has tobe grounded.The pump should be connected to a singlephase power source.Color coding for wires:Blue - LiveBrown - NeutralYellow/Green - Ground (earth)

• Slip a hose connectoronto the hose over thehead valve and up tothe bottom of thethreads ensuring it isfully seated.

• Slide the connector upto the threads andtighten to form a seal.

• Slip the ceramic weight(HI 721008) and a con-nector over the other endof the hose.

EXAMPLE OF TYPICAL INSTALLATIONS

Flooded Suction Installation

Suggested Installationfor consistent outputwhen using a lowstroke rate. Also sug-gested for highly vis-cous chemicals.

A slight suction pres-sure avoids self-prim-ing problems, espe-cially with high viscos-ity liquids.

Suction Lift Installation

Suggested installationfor most in-line appli-cations with nominaloutput and pressures.

The maximum self-priming height is 1.5m (5 ft.). It is advisableto install a level con-troller in order to stopthe pump when feedtank liquid level is low.

Assembling the Hose to the ValveThe end of the valve is specially tapered toform a leak free seal when the hose is prop-erly installed.Be sure to seat the hose completely so thatthere is no gap. Push the hose until it coversthe end of the valve completely.

Suction and Discharge ValvesThe suction and discharge valves located onthe pumphead should not be interchanged asthey are different internally. The dischargevalve is fitted with a valve guide and will notfunction properly if used on the suction side.

OPERATIONAL GUIDE

START-UP

At start-up, purge all chemical gases and airfrom the suction tubing, valves and pumphead. Start the pump.

When all the air or gas is vented, the solu-tion being metered will appear in the outputline.

Note: Only when operating under pressure,the pump must be started unloaded.

An external Flow RateControl (potentiometer) onthe face of the pump al-lows to adjust the flow upto 100% of the pump'srated capacity.

A LED indicator will light up each time astroke begins.

Uphill Installation

Suggested installationwhenever the supply islocated higher than thedischarge point; typi-cally a waste water ap-plication.

It is important to in-stall the Injection valveto prevent siphoning.

Downhill InstallationSuggested installation when pumping fromone container to another, each at differentlevels and with only nominal pressure.

TROUBLESHOOTING GUIDE

Electrical

The pump does not operate when turned ON:• Check the power supply and connections.Voltage should be between 100 - 130 Vacfor -1 models and between 200 - 240 Vacfor -2 models.

• Check wiring color scheme. See Installa-tion section or call for technical assistance.

Liquid

The pump operates but does not prime:• Check for a clogged or loose filter on thesuction valve assembly. Retighten ifnecessary.

• Check to see if the pump is too high abovethe foot valve assembly (HI 721005) in thefeed tank. This vertical distance should not

4. Switch the pump ON tothe estimated setting andrun for a specific amountof time (e.g. 1 minute).Count the number ofstrokes, length of time,and volume pumped.

Note: It is suggested that you run the test foras long as possible to maximize theaccuracy.

For example, if at the maximum setting of100% you find you pumped 200 mL in oneminute, your hourly output would be 12 li-ters/hour (200 mL x 60 min. = 12000 mL/hr).If your application called for 9 liters/hour,turn the Flow Rate Control to 7 (9/12). Runthe test again to verify the results.

Operating Pressure and Back Pressure

Operating pressure is a combination of backpressure plus all of the other resistances toflow present in your system.BlackStone Pumps are designed to dose theirrated output at the operating (rated) pressure.Therefore, rated pressure of the pump youinstall should be close to operating pressurepresent in the system.Too little back pressure can cause the pumpto overdose.To prevent this from happening on a low backpressure installation, a spring has been addedto the discharge/anti-siphon valve assembly(HI 721004).When pumping into a high back pressure,the spring should be removed.

Actual Flow RateThe actual flow rate depends upon the oper-ating pressure which includes resistance atthe injection fittings, hose and piping, thechemical viscosity and suction lift. The FlowRate Control adjusts the flow up to 100% ofthe rated output. Less back pressure willincrease the output, more will decrease it.To determine the correct setting for yourapplication, use the following procedure.1. Be sure that the pump is primed and that

the output connections are completed atthe injection point.

2. Place the foot valve assem-bly (HI 721005) in a gradu-ated container with 500mL of the solution to bedosed.

3. Switch the pump from OFFto the 100% setting andrun until the system hasbeen fully reprimed. SwitchOFF and refill the containerto the 500 mL level.

MAINTENANCE

Your BlackStone Pump is designed to giveyou years of trouble-free service. Mainte-nance should be the preventative type, thatis, periodic cleaning and inspecting for anydamage or leakage.

Cleaning the Suction, Discharge and In-jection ValvesRemove the valves from the pumphead,the injection fitting and the feed.

Keep the suction and discharge valves sepa-rated as they are not interchangeable.

Disassemble each valve and clean it with aneutral liquid. Inspect the PVDF springs.

After cleaning the glass balls, inspect themfor any excessive wear due to abrasion fromthe chemical. Replace if necessary with partsfrom HI 721102, HI 721103, HI 721104 andHI 721105.

When reinstalling the valves into thepumphead, tighten by hand first and thenwith a wrench ¼ to ½ turn.

Inspecting the hose (if used as suppliedwith the pump)

Inspect to see if the hose has worn out orweakened due to the chemicals. Pay par-ticular attention for any signs of abrasion ordiscoloration. Also check the connectors toensure they are tight.

Replace if necessary with parts from HI720032.

exceed 1.5 meters (5 feet). Either lower thepump or raise the feed tank.

• Check the pumphead, suction anddischarge valves for blockage.

Pump flow rate is reduced:• Check the pumphead, discharge and injec-tion valve assembly for any clogging. Cleanand reassemble.

• Check for any additional back pressure cre-ated since the last flow rate was conducted.

• Check for any changes in the viscosity ofthe chemicals being used. Increase the %flow by adjusting the Flow Rate control to ahigher setting and run a Flow Rate test.

• Be sure that valves have been properly in-stalled in the pumphead.

Leakage at the connections:• Be sure that the hose is fully seated andhose connectors are tight.

• Be sure that valves are tight and O-ringsare in place.

Leakage around the pumphead:• Be sure that the valves are tight and O-rings are in place and the head screws(hex bolts) are tight.

CHEMICAL COMPATIBILITY GUIDECleaning the Pumphead

The pumphead should be cleaned at regularintervals and at least once a year. Removethe deposits that form in the cavities with asolution that is neutral to the chemical thepump has been dosing. Inspect the headfor any cracks or worn areas.

Replace if necessary with parts from thepumphead spare part HI 721106 (for BL7,BL10, BL15 and BL20) or HI 721107 (forBL1.5, BL3 and BL5).

SCHEDULED MAINTENANCEAfter 50 hours

Tight the pumphead screws with a torqueforce of 2.5 Nm (22" lbf).

After 12 months

It is recommended to replace HI 721102, HI721103 (suction and discharge valves as-semblies) as well as the O-rings. The LDPEhose can also deteriorate over time and, forsafety reasons, should also be changedwith HI 720032.

After 24 months

It is recommended to replace HI 721102, HI721103, HI 720032 and HI 721106 (for BL7,BL10, BL15 and BL20) or HI 721107 (forBL1.5, BL3 and BL5).
