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.

The O-ring is also called the sealing ring, It is a kind of rubber sealing ring with circular cross section, which is the most common mechanical design for sealing.

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.

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.

1/4 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 Inch High-efficiency Aluminum alloy Air Diaphragm Diaphragm Water Pump is a new type of pneumatic reciprocating conveying machinery, powered by air, can transport a variety of properties of liquid.

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.

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