Diaphragm Pumps

Diaphragm pumps are positive displacement pumps which, through the action of reciprocating diaphragms draw fluid into the pump during the suction phase and then push it out under pressure during the discharge phase. The outlet flow is determined by the size and number of chambers and is in direct relation to the RPM of the pump. The discharge pressure is primarily determined by the restrictions applied to the flow, be it through nozzles or other downstream restrictions.

Diaphragm pumps are self-priming, have good dry-running capabilities, and offer good mechanical and chemical resistance. Diaphragm pumps are ubiquitous in agricultural spraying and weeding treatments but are also widely used in a broad range of processes and applications from chemical processing, pharmaceuticals, food and beverage, carwash, window cleaning, water treatment, pressure testing and more.
