What is an Electric Diaphragm Pump
A diaphragm pump is a positive displacement pump which operates with a flexible diaphragm, and integrated check valves. The diaphragm is moved inward & outward toward the pump body which works in conjunction with the check valves and draws in and expels the fluid out the pump casing.
An Electric Diaphragm Pump is mechanically driven as opposed to air operated. For applications where there is an Explosive Atmosphere, we have ATEX Certified conductive pumps.
These pumps are available in a single diaphragm configuration, and also a double diaphragm configuration
Applications for Mechanically Operated Diaphragm Pumps
Electric Diaphragm pumps are used extensively in the food processing industry and related general industrial applications.
Types of Diaphragm Pump Electric
Positive Displacement Pump
The positive displacement pump provides an approximate constant flow at fixed speed, despite changes in the counter pressure.
Positive displacement pumps all pulsate, meaning that their volume flow within a cycle is not constant. The variation in flow and speed leads to pressure fluctuations due to resistance in the pipe system and in valves.
