Electric Diaphragm Pumps

Electric diaphragm pumps are positive displacement pumps designed for controlled fluid transfer in industrial applications, OEM systems, and compact installations. The alternating movement of the diaphragm ensures consistent flow and pressure with reliable operation and compact dimensions.

How to choose an electric diaphragm pump

To select the most suitable electric diaphragm pump, it is important to evaluate key parameters related to the application and operating conditions.

  • Required flow rate (L/min)
  • Operating pressure (bar)
  • Type of application
  • Available power supply (AC / DC)

How electric diaphragm pumps work

Electric diaphragm pumps operate through the alternating movement of a diaphragm driven by an electric motor and eccentric mechanism. This motion creates a variation in chamber volume that allows fluid to be drawn in and discharged through non-return valves.

Frequently asked questions about electric diaphragm pumps

Can a diaphragm pump run dry?

In most configurations, diaphragm pumps can tolerate short dry-running periods, but proper application design is always recommended.

What is the maximum pressure of a diaphragm pump?

Maximum pressure depends on the model and configuration. In industrial applications, diaphragm pumps typically operate between 3 and 8 bar.
