    It takes the air as momentum which compressed by air compressor. The needle valve adjust the air flow, which drive the membrane, then the pump transport the liquid.



  1. Because it is using air as power, the diaphragm pump does not heat and produce sparks; suitable for use in flammable and explosive environment.
  2. Use Special material diaphragm, can be used for chemical properties relatively volatile liquid, corrosive medium.
  3. Diaphragm Pump can pump particle liquid;
  4. The liquid can be conveyed by diaphragm pump is wide, the viscosity from low to high, from corrosive liquid to viscous liquid.
  5. Diaphragm Pump is small, light and easy to move.


    Used for coating, circulation, transmission of water-based ink printing machine, gravure printing, flexo printing and the ink on the compound machine, glue, and the liquid with particle, inflammable liquid.

1. Low air consumption, the medium flow regulation is stepless regulation, and it is adjusted by air inlet valve.
2. Membrane is made of corrosion resistant material, so it can be used to transport corrosive medium.
3. Low failure rate, easy to install, convenient maintenance.
4. The pump shell is made of high quality material, the inner parts are made of stainless steel and copper, all of those make the pump light, beautiful, stainless and anticorrosive.
