Double Diaphragm Pump

Air Operated Diaphragm Pumps

Air diaphragm pumps are specifically designed to pump abrasive fluids with high loads of solids or high viscosity. Furthermore, air diaphragm pumps are often used if the pumped liquid has a limited acceptance of shear forces which denies the use of a centrifugal pump. Air diaphragm pumps are dry-run capable, dry self-priming, and continuously adjustable. In addition, our air operated diaphragm pumps don’t have a dead-center as a result of a lube-free air valve system, which guarantees a continuous and trouble-free operation.

The series MPF air diaphragm pump is available in plastic such as PP (Polypropylene), PVDF (Polyvinyldene fluoride), and conductive PP and PVDF. The pump is also available in aluminum and stainless steel. In combination with a variety of membranes and valve materials, these pumps can be used with almost all liquids.
