Membrane Casting Steel Diaphragm Pump / Diaphragm Liquid Pump

Pneumatic Diaphragm Pump Advantages:

Idling ,Self-priming , Submerse capability.
Provide stall-free, ice-free zero leak operation.
Epoxy-coated air section for tough environmental conditions.
Low shear force , not easy to damage the material structure.
Bolt joint design provides even sealing pressure for optimal performance
Modular air valve,low pulsation operation,providing smooth and rapid changeover.
No electricity . It's safe and realiable while using in the flammable and explor place .
Diversity of material,no rotating parts,applicable to various erosive situations.
Can pump corrosive , volatile, flammable, poisonous fluids with particles and high viscosity.
Delivery lift and flow can pass the pneumatic valve open to realize the stepless adjustment

Application:

It is widely applied in waste water treatment, chemical industry, petrochemical
industry, painting, ceramics, environmental protection, printing and dyeing, etc. to deal with all kinds of
corrosive, volatile, flammable, poisonous fluids with particles and high viscosity.

Working Principle
In the two symmetrical pump chamber equipped with a diaphragm, which is connected by a center couplet stem. Compressed air comes in from pump inlet valve, and enter into one cavity, push the diaphragm movement, and gases emitted from another cavity. Once to the destination, gas distribution components will automatically compressed air into another chamber, push the diaphragm to the opposite direction, thus make two diaphragm continuous synchronization to reciprocating movement.

Compressed air goes into the valve, make the diaphragm to the right movement, and chamber suction make medium enter into, push the ball into the room, ball valve shuts down due to inhalation, Mediums discharged by extrusion, and opened the ball valve and at the same time close the ball valve, prevent back flow, thus to make medium ceaseless from the entrance inhaled, exit eduction.
