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)
Quick selection guide
- High flow rate : 550 Series
- High pressure : 5800 Series or 6800 Series
- Precision dosing : 6800 Series
- Reverse osmosis systems : 8800 Series
- General OEM applications : 550 Series or 5800 Series

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.
