Low Pressure Plastic Air Driven Double Diaphragm Pump For Strong Acid Strong Alkali Liquids

Industrial Plastic Positive Displacement Water Pumps Low Pressure Diaphragm

Air 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.

1. Positive Displacement Water Pump Description
1. Double Diaphragm Pump Air Operated Double Diaphragm Pump Rubber Diaphragm for Pump for Food& Chemical, Chemical Resistant Diaphragm Pump is the new kind of transportation machine, adopting compress air, smoke and industry exhaust gas as power source.
2. It has two diaphragms, the compressed air come to the pump body to drive the pump in the constant action of sucking and releasing, so it can pump the liquids easily by this principle. Also it is very safe in dangerous environment since it has no electric motor.
