Two Way Portable Diaphragm Pump Strong Acid Air Operated Reciprocating Pump

Double Acting Polypropylene Diaphragm Pump Air Driven Submersible

Air diaphragm pump

(also know as a Membrane pump, air operated double diaphragm pump(AOOD)or pneumatic diaphragm pump)that uses a combination of the reciprocating action of a rubber,thermoplastic or diaphragm and suitable valves either side of the diaphragm (check valve,butterfly valves,flap valves,or any other form of shut-off valves) to pump a fluid.

Air Diaphragm Pump

1. Non leakage
2. Good self priming performance
3. Convey all kinds of medium
4. Material:Cast steel,Alu,SS,PP

Application

 
The pump can suck various strong acid, alkali and corrosive liquid etc.

General Description

The  diaphragm pump offers high volume delivery even at low air pressure and a b road range of material compatibility options available.Refer to the model and option chart.The  pump is provided with the modularized air motor and fluid section.

The air operated diaphragm pump alternately generates the intake fluid pressure and positive fluid pressure in the fluid chamber by using the pressure difference in the air chamber. The ball valve can ensure the forward flow of fluid.

Pump cycling will begin as air pressure is applied and it will continue to pump and keep up with the demand. It will build and maintain line pres -sure and will stop cycling once maximum line pressure is reached (dis -pensing device closed) and will resume pumping as needed.

FLUID SECTION DISASSEMBLY

• Remove the upper and lower manifold (1) and (11).

• Remove the ball (2), “O” ring (3) (47) and ball seat (4).

• Remove the fluid cap (5).

    NOTE: Only diaphragm models use a primary diaphragm(6A) and a backup diaphragm(6). Refer to the aux iliary   view in the Fluid Section illustration.

• Remove the screw (10), washer (9), diaphragm (6A, 6) and diaphragm washer (7, 8).
  NOTE: Do not scratch or mar the surface of (23) diaphragm rod.

FLUID SECTION REASSEMBLY

• Reassemble in reverse order.

• Clean and inspect all parts. Replace worn or damaged parts with new parts as required.

• Lubricate (23) diaphragm rod and 25) “Y” ring with grease.

• Fix the diaphragm rod (23) with the auxiliary installation tool.

• Prior to the final fastening of bolts and nuts, please determine whether the diaphragm (6A,6) is aligned with the fluid cap (5) properly to avoid the twisting of the diaphragm.

• For the models using diaphragm: three rubber diaphragms (6) on the side, which are marked with AIRS SIDE "air chamber" are mounted in face of the pump body.

• Start the pump, check the fastening and sealing after it runs for a period of time.
