Air pressure operated diaphragm pump properties:
High roundness valve ball, enhance check valve seal.
Four bolts connection design, strong and good dry suction. Actual dry suction can reach to 4~7m.
Three section manifold, Flexible installation and even can change to be four ports pump.
Longer diaphragm life. Raw material from Dopont, Exxon. Dakin.
Aluminum pump and stainless steel pump adopt precision casting, smooth surface.
Plastic pump adopt flange connection, stronger than thread connection.
Wetted body: PP, PVDF, POM, SS304/316, Aluminum etc.
Diaphragm: Tefe,PTFE, Hytrel ,Buna-N, Santoprene ,EPDM, Viton etc.
