Air pressure operated diaphragm pump
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.

Stainless Steel Pump (SS304/316)
High temperature wax casting, heat treatment and shaping processing. Smooth surface and good appearance.
Liquid chamber and manifold adopt 4 bolts connection. Good seal, the actual dry suction can reach to 4~7m.
Origin stainless steel color. The pump surface adopt pickling and electrolytic processing.
Can supply stainless steel 304 /316 pump from 1/2" to 3".
The bolts of stainless steel pump are of Stainless steel 304.
Plastic Pump (PP-H, PVDF, Acetal)
Three section manifold, Flexible installation. Can change to be 4 ports pump.
Enhanced structural strength, the plastic pumpbody is durable.
Solid flange connection, strong and durable.
Raw material is PP-H which low temperature resistance, high temperature resistance, chemical resistance, wearing resistance better than PP.
Liquid chamber and manifold adopt 4 bolts connection. Good seal and good dry suction.
The bolts of plastic pump are of Stainless steel 304.
can supply PP-H pump and PVDF pump from 1/2" to 3".
Aluminum Pump
Aluminum material grade is A356.
Pump adopt precision casting, smooth surface.
Three section manifold, Flexible installation. Also can change to be 4 ports pump.
Liquid chamber and manifold adopt 4 bolts connection. Good seal and good dry suction.
Bolts of aluminum pump are of stainless steel 202.
Can supply aluminum pump from 1/2" to 3".
Enhanced structural strength, the aluminum pumpbody is durable.
