Silent Membrane Dosing Pump , Custom Made Electric Double Diaphragm Pump
Membrane Dosing Pump Introduction
The air operated diaphragm pumps use compressed air as power source, and it is the most advanced
type of diaphragm pumps in market for the moment. It adopts three-way air pilot valve to achieve real
no dead stop and faster reversing. It is widely applied in waste water treatment, chemical industry,
petrochemical industry, painting, ceramics, environmental protection, printing and dyeing, etc. to deal
with all kinds of corrosive, volatile, flammable, poisonous fluids with particles and high viscosity.
Air diaphragm pump(also know as a Membrane pump, air operated double diaphragm pump(AOOD) or pneumatic diaphragm pump)that uses a combination of the reciprocating action of a rubber,thermoplastic or diaphragm and suitable valves either side of the diaphragm (check valve,butterfly valves,flap valves,or any other form of shut-off valves) to pump a fluid.
