Flange

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.

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.

1.5 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.

The air diaphragm pump has the function of self priming without rotating parts. It can achieve dry priming and wet priming, which self -priming height is 5m and 8m respectively.

AOK50 high flow flap valve Air Operated Diaphragm Pump liquid flow is spacious and good through performance, It is a Large particle passing capacity diaphragm pump, It has a strong capacity for the passage of large solid particles. allowing passage of solid particles with a maximum particle diameter of 40 mm. This aluminum alloy flap valve air operated diaphragm pump is very popular in chemical industry. 

AOK50 PVDF self priming AODD pump is easy to use, reliable and simple to operate. When the 2inch PVDF air powered diaphragm pump accident will automatically stop, with good self-protection performance. When the AOK50 pneumatic diaphragm pump everything back to normal, and can automatically start running.

AOK15 Polypropylene air diaphragm pump is a kind of air operated double diaphragm pump for sulphuric acid with good chemical stability, has strong acid and alkali corrosion resistance. 

Aluminum alloy double diaphragm pump not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits of self priming pump, slurry pump and impurity pump, etc. It is an excellent aluminum alloy diaphragm pump.
