charging pneumatic diaphragm pump

Features of pneumatic diaphragm pump:
Patented design of unbalance air valve, no death point
The application of wiper "O" type loop in air valve to ensure low abrasive wear of air valve
Self lubricating, maintenance free.
Quick Exhaustion structure to ensure no icing at gas valve (2" and 3" pump )
Very low leakage
Bolt joining structure, easy assemble/disassemble
Passed the certification of ISO9001 and CE of EU
One year's warranty of the main body of pump(not including wearing parts)

Advantages of pneumatic diaphragm pump:

Dry running is allowed
No electric spark
Optional materials are suitable for most fluids
The passing of solid granules is allowed
Automatically adjust flux according to back pressure
Low shearing force, not easily destroy the structure of materials
Needs no foundation and is mobile;
