Corrosive Liquids Air Driven Double Diaphragm Pump With Large Flow Rate

Air Driven Double Diaphragm Pump introduction

Air Driven Double Diaphragm Pump produced by our company is a new type of conveying machine, which can convey various corrosive liquids, liquids with particles, highly viscous, volatile, flammable and toxic liquids.

Pumps are made of four materials according to different applicable conditions: plastic, aluminum alloy, cast iron and stainless steel.

Diaphragm pumps adopt Ding Qing rubber, neoprene, fluororubber, polytetrafluoroethylene and polytetrafluorethylene respectively according to different liquid media.

So as to meet the needs of different users.

Installed in various special occasions, it can be used to pump various media that cannot be pumped by conventional pumps, with satisfactory results.

Diaphragm pumps are widely used in paint spraying and ceramic industries.

pneumatic diaphragm pump uses air as power, so the flow rate automatically adjusts with the change of back pressure (outlet resistance), which is suitable for medium and high viscosity fluids.
