Membrane Air Driven Double Diaphragm Pump Casting Steel Diaphragm Pump

Membrane Casting Steel Diaphragm Pump / Diaphragm Liquid Pump

Casting Steel Diaphragm Pump Introduction

Air diaphragm pump is a new type of conveyor machinery, adopts compressed air as power source, suitable for various corrosive liquid, with particles liquid, high viscosity and volatile, inflammable, poisonous liquid. The main characteristic of this pump is no priming water needed, can pumping the medium that easy to transport. High suction head, adjustable delivery head, fire and explosion proof.

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.

Casting Steel Diaphragm Pump Specifications

Air Diaphragm Pump
1. Non leakage
2. Good self priming performance
3. Convey all kinds of medium
4. Material:Cast steel,Alu,SS,PP

Casting Steel Diaphragm Pump Main Advantages

1, Due to the use of air power, the flow automatically changed according to export resistance. Which is suitable for high viscosity fluid.
2, In inflammable and explosive environment, the pump is reliable and low cost, won't produce spark and not overheat,
3, The pump volume is small, easy to move, no foundation needed, convenient installation and economy. Can be used as mobile conveying pump.
4, Where there are dangers, corrosive materials processing, diaphragm pump can be separated completely with outside.
5, The pump shearing force is low, physical effect to medium is small, can be used for conveying unstable chemistry fluid.
