Aro Rubber Diaphragm Pumps With No leakage , Gas Diaphragm Pump
Gas Diaphragm Pump Application and Advantage:
Pneumatic diaphragm pumps are operated with compressed air .
diaphragm pumps is suitable for pumping fluids with particles, and
various liquids, which are highly viscous, volatile, corrosive or
toxic, as well as colloids. The pump body is made of aluminum
alloys, cast iron or stainless steel. The diaphragm is made of high
quality rubber such as Nitrile rubber, chloronorgutta rubber,
fluoroine rubber. The diaphragm pumps are widely used in the
petroleum chemical, electronic, ceramic, food and textile
industries.
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.
