qby3 pneumatic diaphragm pump is the Shanghai edge pump Manufacturing Co., Ltd. produced a new generation of products. Reliable quality and long life, low noise, small vibration, never crash, fine workmanship and other six major advantages. 1, the concept of the United States, the pickling process is made, do not have to worry about in the delivery of food-grade paint peeling trouble; 2, the valve with built-in installation, so that the pump is running, will not produce crashes; pump volume Small, easy to move. 3, the pump without irrigation, suction up to 5 meters, lift up to 70 meters, the outlet pressure ≧ 7bar; 4, flow spacious, through the good performance, allowing the maximum particle diameter of 10 mm. Pumping slurry, impurities, the pump wear is minimal; 5, head, flow through the valve opening to achieve stepless regulation (pressure regulation between 1-7bar 6, the membrane sheet with imported plastic diaphragm and Teflon Long diaphragm, corrosion-resistant, long life 7, the pump without rotating parts, there is no shaft seal, diaphragm and other pumping medium and pump moving parts, the workpiece medium completely separated, the media will not leak outward delivery.So pumping Toxic, volatile or corrosive media will not cause environmental pollution and endanger personal safety 8, the structure is simple, less wearing parts, the pump structure is simple, easy installation, maintenance, pump delivery medium will not come into contact with the valve Unlike the other types of pumps due to the rotor, piston, gear, blades and other parts of the wear and tear and the gradual decline in performance 9, can deliver a more viscous liquid (viscosity below 10,000 cps); 10, The pump without oil lubrication, even idling, the pump has no effect, which is a major feature of the pump;
