Diaphragm Pumps

Diaphragm pumps are positive-displacement pumps that move fluids through a reciprocating action of a flexible diaphragm, driven mechanically, hydraulically, or pneumatically. Check valves ensure one-way fluid flow while the diaphragm alternately creates suction and discharge in the pump chamber. These pumps are highly versatile—self-priming, capable of dry running, and well-suited for handling abrasive, viscous, corrosive, or shear-sensitive fluids across chemical, wastewater, pharmaceutical, and food-processing industries.
