Aluminum mining air operated double diaphragm pump low density, high strength. It can be used for transporting chemically unstable fluids.

AOK50 High Viscosity Medium Air Operated Reciprocating Self Priming Diaphragm Pump without oil lubrication, even idling on the pump without any impact.

1.5 inch AOK high performance air operated diaphragm pump can be used according to different liquid medium different materials, in order to meet the needs of different users.

The valve ball materials are Teflon, Santoprene, EPDM, ect. It has a very low friction coefficient, excellent self-lubrication, good corrosion resistance, dimensional stability, and no deformation.

2 inch plastic self priming diaphragm pump has a very strong self-priming function. The use of 2 inch pp air diaphragm pump without rotating parts, dry and wet absorption can be achieved.

1/4 Inch Portable Mini Air Operated Double Diaphragm Pump does not need to divert water, both can pump flowing liquid, and can transport some not easy to flow medium. 

Diaphragm has Teflon (PTFE), Viton, Buna-n, Neoprene, Santoprene, EPDM, etc. materials. That is imported material, the diaphragm stress of air operated diaphragm pump is reduced to the minimum, and the service life is extended.

Food grade self priming AODD pumps are ideally suited for applications that require a robust, plug-and-play, and easy-to-maintain stainless steel two diaphragm air pump.
