1. Air Chamber The air chamber is the chamber that houses the
air which powers the diaphragms.
2. Air Distribution System The air distribution system is the heart of
the pump. The air distribution system is the mechanism that shifts the pump in order to create suction and discharge strokes.
3. Lock Nut (Outer Diaphragm Piston) The outer diaphragm pistons provide a means
to connect the diaphragms to the reciprocating common shaft and to seal the liquid side from the air side of the diaphragm.
4. Holding plate (Inner Diaphragm Piston) The inner piston is located on the air side of the
pump and does not come into contact with the process fluid.
5. Check Valve Ball TABLA air-operated pumps use suction and
discharge check valves to produce directional flow of process fluid in the liquid chamber. The check valve balls seal and release on the check valve seats allowing for discharge and suction of process fluid to occur.
6. Check Valve Seat The removable seats provide the ball valves a site
to check.
7. Discharge Manifold Process fluid exits the pump from the discharge
port located on the discharge manifold at the top of the pump.
8. Liquid Chamber The liquid chamber is filled with the process fluid
during the suction stroke and is emptied during
the discharge stroke. It is separated from the compressed air by the diaphragms.
9. Diaphragm The diaphragm membrane provides for separation
of the process fluid and the compressed air power source. To perform adequately, diaphragms should be of sufficient thickness and of appropriate material to prevent degradation or permeation in specific process fluid applications. TABLA offers a variety of diaphragm materials for your specific application requirements.
10. Inlet Manifold Process fluid enters the pump from the intake
port located on the inlet manifold at the bottom of the pump.

Lift away the discharge manifold to expose the valve balls and seats.
Remove the discharge valve balls, O-rings and seats (Fig 4) from the liquid chambers and inspect for nicks, gouges, chemical attack or abrasive wear. Replace worn parts with genuine TABLA parts for reliable performance.
Remove the discharge valve balls, O-rings and seats (Fig 7) from the liquid chambers and inspect for nicks, gouges, chemical attack or abrasive wear. Replace worn parts with genuine TABLA parts for reliable performance.
Before starting disassembly, mark a line from each liquid chamber to its corresponding air chamber. This line will assist in proper alignment during reassembly.
Utilizing a wrench, remove the bolts that fasten the discharge manifold to the liquid chambers.
Remove the bolts which fasten the suction manifold to the liquid chambers.
DISASSEMBLY
Lift suction manifold from liquid chambers and centre section to expose intake valve balls and seat. Inspect ball cage area of liquid chamber for excessive wear and damage.
Directions For Disassembly & Reassembly D 50 Polypropylene Bolted
CAUTION: Before any maintenance or repair is attempted, the compressed air line to the pump should be disconnected and all air pressure allowed to bleed from the pump. Disconnect all intake, discharge, and air lines. Drain the pump by turning it upside down and allowing any fluid to flow into a suitable container. Be aware of any hazardous effects of contact with your process fluid.
TOOLS REQUIRED:• Wrench• Allen Wrench• Adjustable Wrench• Adjustable Spanner• Vise equipped with soft jaws (such as plywood, plastic or other suitable material)

Remove one set of bolts, which secure one liquid chamber to the center section.
STEP 13
STEP 10
Lift liquid chamber away from center section to expose diaphragm and lock nut (outer piston).
Normally inlet and discharge manifolds should not be disassembled during regular pump maintenance. Should this be necessary, completely remove clamp bands and inspect O-rings for nicks, cuts and chemical attack.
Using an adjustable wrench, or by rotating the diaphragm by hand, remove the diaphragm assembly.
NOTE: Due to varying torque values, one of the following two situations may occur:
1) The lock nut (outer piston), diaphragm and holding plate (inner piston) remain attached to the shaft and the entire assembly can be removed from the center section (Fig 12).
2) The lock nut (outer piston), diaphragm and holding plate (inner piston) separate from the shaft which remains connected to the opposite side diaphragm assembly (Fig 13). Repeat disassembly instructions for the opposite liquid chamber. Inspect diaphragm assembly and shaft for signs of wear or chemical attack. Replace all worn parts with genuine TABLA parts for reliable performance.
To remove diaphragm assembly from shaft, secure shaft with soft jaws (a vise fitted with plywood or other suitable material) to ensure shaft is not nicked, scratched, or gouged. Using an adjustable wrench or by hand, remove diaphragm assembly from shaft. Inspect all parts for wear and replace with genuine TABLA parts if necessary.
REASSEMBLY
STEP 12
Upon performing applicable maintenance to the air distribution system, the pump can now be reassembled. Please refer to the disassembly instructions for photos and parts placement. To reassemble the pump, follow the disassembly instructions in reverse order. The air distribution system needs to be assembled first, then the diaphragms and finally the wetted parts. Please find the applicable torque specifications on this page. The following tips will assist in the assembly process.• Clean the inside of the center section shaft bushing to
ensure no damage is done to new seals.• Stainless bolts should be lubed to reduce the
possibility of seizing during tightening.• Ensure proper alignment on the sealing surfaces of
intake and discharge manifolds.• Liquid chambers are easier to attach when the
diaphragm is inverted. Prior to attaching the second water chamber, push diaphragm assembly so that it is as close as possible to the center section.
• PVDF pumps require Teflon® gasket kits for improved sealing. Gasket kits may be installed on other pumps where sealing is an issue.
