1.5 inch Polypropylene air operated duplex diaphragm pump polypropylene material density is relatively small, is also one of the lightest plastic diaphragm pump material. Therefore, the 1.5 inch pp pneumatic diaphragm pump is very light and convenient and has strong mobility.

Pneumatic coupling refers to air filter and pressure reducing valve. The pressure reducing valve can stabilize the pressure of the gas source, so that the gas source is in a constant state, which can reduce the damage to the valve or actuator and other hardware when the air pressure of the gas source changes abruptly. The filter is used to clean the air source. It can filter the water in the compressed air and avoid the water entering the device with the gas.   

1 inch pp pneumatic diaphragm pump is also known as corrosion resistant engineering plastic AODD pump, Its flow pump body part is made of polypropylene, is not rust, no pollution, strong corrosion resistance of the 1 inch diaphragm pump for paints & solvents.

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.

Quick Connector is a joint that can connect or disconnect pipes without tools.  The operation is simple, time saving and manpower saving when disconnecting and connecting with quick connector.

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. valve seat: The valve seat materials are Teflon, Santoprene, Buna-n, ect.

Removable Muffler: The pump body installed with muffler, the delivery head and flow can pass the pneumatic valve open to realize the step less adjustment. Effectively reduce air duct noise. 

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