Plastic PP Polypropylene Membrane Pump

2inch polypropylene air operated duplex diaphragm pump can be used directly as a submersible pump, it uses air as the power source, and does not have the leakage and other security risks. This diaphragm pump has lower cost than submersible pump which is caused by the maintenance of motor.

AOE100 air operated double diaphragm pump with sectional type structure, this self -priming pump can be used for conveying two different liquid by double diaphragm.

1.5 inch plastic air operated double diaphragm pump AODD 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 1.5 inch diaphragm pump for paints & solvents, acid liquid.

1/2 inch mini polypropylene pneumatic diaphragm pump has six advantages, such as reliable quality, long service life, low noise, small vibration, high head, never crash and fine workmanship.

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. 

PVDF Air operated double diaphragm pump with strong chemical resistance, crush resistance, abrasion resistance, good corrosion resistance for acid, alkali and variety of organic solvents.

Flexible Hose: Explosion-proof flexible connecting pipe is suitable for combustible dust environment, It has the advantages of fire resistance, corrosion resistance, water resistance, aging resistance, good flexibility, firm structure and reliable operation. Chemical hose: Can be widely used to transport corrosive chemical liquids and gases, excellent chemical resistance. The special construction process makes it cost-effective, light, soft, easy to operate and durable.

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.
