High Pressure Pneumatic Diaphragm Pump For Waste Water Treatment Industrial

Pneumatic Diaphragm Pump description

1, No electricity. It's safe and reliable while in the flammable and explore places.

2, Pump has no rotary parts and bearing seals. The diaphragm will completely separate the exhausted medium and pump running parts, working medium. There's no leakage, thus it doesn't cause environmental pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium.

3, It's convenient to use and reliable to work. This pump is simple in structure and easy to be installed and maintained.

The medium conveyed doesn't touch the matched pneumatic valve and coupling lever etc. While normal pumps' performance will be decreased gradually because of the damages of driving parts.

4, This pump doesn't need oil lubricant, even works in dry run.

Air diaphragm pump(also know as a Membrane pump, air operated double diaphragm pump(AOOD) or pneumatic diaphragm pump)that uses a combination of the reciprocating action of a rubber,thermoplastic or diaphragm and suitable valves either side of the diaphragm (check valve,butterfly valves,flap valves,or any other form of shut-off valves) to pump a fluid.
