Diaphragm Pump

A diaphragm pump is a positive displacement pump that uses a combination of reciprocating action and either a flapper valve or a ball valve to transfer liquids. This pump is sometimes referred to as a membrane pump. Diaphragm pumps are self-priming and are ideal for viscous liquids. Most models are available in electric, engine, manual, air operated or hydraulic configurations.


  • Explosion-proof, zero leaks, simple operation
  • leading capability, Self-suction, No complex control
  • Can transmit the adhesive liquid and large particles
  • low shearing, Not easy to destroy the material structure
  • The diversity of material, no rotating parts, applicable to various erosive situations
  • By changing the air supply to adjust the flow delivery
  • By changing the air pressure to adjust the pump lift
  • Once over-loading, the pump will automatically stop
  • No mechanical seat, easy maintenance, low cost.
  • Modularization of the main valve and air motor, No broken, easy to disassemble and repair.
