How does the EVO Series™ Electric Diaphragm Pump Work?

The EVO Series design delivers the benefits of air operated diaphragm pumps and positive displacement pumps. With three diaphragms and efficiency and control features the EVO Series is an all-in-one-solution. 

Electric diaphragm pumps operate using a linear back-and-forth motion through a crankshaft system. This creates suction and discharge of the fluid.
