3- DIAPHRAGM PUMP DEFINITION

Diaphragm pump works with the electrical energy coming from the electrical engine and the cam

system converts the circular motion into linear motion. Pump working principle is showed in the

below illustration.

Diaphragm pump is mounted to the ground or on a tripod from its legs with bolts.

Electric driven pumps are suitable in transferring the fluids up to 50,000 cP viscosity.

RIGHT STROKE

Diaphragm is directed between A-B

line by the linear motion of the cam

system. The movement in the B

direction pushes the B diaphragm and

pulls the A diaphragm. While B

diaphragm presses the liquid to the

outlet, A diaphragm creates the

vacuum within the A chamber. This

vacuum causes the valve ball open

and the liquid fill the A chamber.

MIDDLE STROKE

Cam system causes the B diaphragm to

create vacuum in the B chamber by

moving the diaphragms in the A

direction. Valve balls position is shown

in the figure at this moment. Open balls

let the liquid pass through and closed

balls prevent the liquid move back at

the pressured state.

LEFT STROKE

The cam system completes the cycle

by moving the diaphragms in the A

direction.

Fix the pump to the ground from its legs.

FLUID LINE

Fluid suction line

1. Use a flexible, non collapsible fluid hose with 1 ” inch inner diameter.

2. If the inlet fluid pressure is more than 25% of the outlet working pressure, ball check valves will not

close fast enough; result will be inefficient pump operation.

Fluid discharge line

1. The pump fluid outlet is 1 ” npt (f). Screw the fluid fitting into the pump outlet securely.

2. Install a fluid drain valve to the pump outlet.

3. Pump is not able to operate in a fluid outlet shut condition. Check the fluid pressure sensor in order

not to exceed the maximal plate measures.
