Stainless steel pneumatic diaphragm pump diaphragm aluminum alloy diaphragm polypropylene diaphragm RG15PVDF

 Shanghai Ren public diaphragm pump fluid machinery company a total of six specifications. Importers and sizes are 1/4 ", 1/2", 3/4 ", 1", 1.5 ", 2", 3 ", 4", the fluid component materials are: aluminum, ductile iron, polypropylene, PVDF , stainless steel, depending on the membrane separator materials were: nitrile rubber, chloroprene rubber, polyethylene, three rubber, polyether rubber, fluorine rubber, PTFE, polyvinylidene fluoride. To meet the needs of different liquid media. Working principle: RG series pneumatic diaphragm pump works: two symmetrical diaphragm working chamber, each equipped with a flexible diaphragm, diaphragm rod will form one of the two, from the pump compressed air into the inlet connector After the intermediate push the two working chamber diaphragm drive link coupled synchronous movement of the diaphragm. At the same time, another work from the back of the gas chamber exhaust diaphragm pump. When the piston reaches the stroke end, with the valve mechanism is automatically compressed air introduced into the other working chamber, pushing the diaphragm toward the reverse movement, thus forming two diaphragms synchronized reciprocation. Each working chamber has set up two-way valve, reciprocating motion of the diaphragm, resulting in changes in the volume of the working chamber, forcing the two-way valve alternating on and off, so that the liquid continuous suction and discharge. RG series pneumatic diaphragm pump diaphragm and other most obvious difference is that with the valve structure. RG series pneumatic diaphragm pump with the valve structure to cancel the traditional "O" ring and the spool valve structure with the valve. Using three-pilot type valve eliminates dead spots and pump downtime. It provides accurate and reliable commutation signal to avoid downtime and faster change to the pump with greater flow, providing transport properties of the pulse smaller, more stable flows. RG series pneumatic diaphragm pump designed to be simple, highly reliable air valve, to ensure non-stop costly downtime costs incurred, all air valve components can be replaced without disassembly of the fluid section. Specially treated aluminum parts can resist corrosion caused by dirty air valve in plastic slider durable, easy to damage, no lubrication, ensure the smooth flow of air passage, the commutation flexible.
