how does an electric diaphragm pump work

The types of diaphragm pumps can be divided into pneumatic diaphragm pump, electric diaphragm pump and hydraulic diaphragm pump according to the power used by the actuator, that is, pneumatic diaphragm pump with compressed air as the power source and electric diaphragm pump with electricity as the power source, In liquid medium (such as oil, etc.)

What is electric diaphragm pump?

Diaphragm pumps are positive displacement pumps. They use a combination of the reciprocating action of two flexible diaphragms, two inlet and two outlet ball check valves to pump a fluid.

There are two pump chambers which are divided by the diaphragms into air and fluid regions.

What are the disadvantages of a diaphragm pump?

1. The pressure cannot be increased, limited by the pressure of the air source, and 6bar is the upper limit;

2. Noise and pipeline vibration are especially obvious when the volume is large;

3. Compared with the screw pump, the diaphragm has a shorter service life and is easily damaged;

4. Because the flow rate of diaphragm pumps is usually not too large, most of them are used in small systems.

Can diaphragm pumps run continuously?

Yes, As long as the diaphragm is intact and the inlet and outlet valves are sealed reliably, the diaphragm pump can work continuously.

What is the lifespan of a diaphragm pump?

Our Pincheng’s Diaphragm pump have 500hrs lifetime. and we can customized accept the other lifespan requirement.
