Air operated diaphragm pump
1.Inlet/outlet diameter: 10-100mm
2.Flow capacity(Q): 0.8-35m3/h
3.Head: 50m
Air operated diaphragm pump are operated with compressed air. RUICHI's hydraulically diaphragm pump work as well as those imported from Germany or USA, suitable for pumping fluids with particles, and various liquids, which are highly viscous, volatile, corrosive or toxic, as well as colloids.
These pumps operate by the movement of two flexible diaphragms, which move back and forth, alternately filling and emptying two chambers. A variety of applications are possible because the pump’s inlets and outlets can be configured in different ways. Air operated pumps are inherently explosion proof. Good for higher viscosities. Pump function produces pulsating flow, so surge suppressor/filter is recommended.
