Product Description

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.

Main Advantages

  • Automatic Flow Adjustment: Flow changes according to export resistance, ideal for high viscosity fluid.
  • Explosion Proof: Reliable in inflammable environments; no sparks or overheating.
  • High Mobility: Small volume, easy to move, no foundation needed.
  • Total Isolation: Can handle corrosive or dangerous materials completely separated from the outside.
  • Low Shearing Force: Small physical effect on medium, perfect for unstable chemical fluids.
