Product Overview of QBY Pneumatic Diaphragm Concentrated Slurry Pump
QBY pneumatic diaphragm mud pump is a conveying machinery and a novel pump type in China. Using compressed air as the power source, it can extract and absorb various corrosive liquids, particulate liquids, high viscosity, volatile, flammable, and highly toxic liquids. The performance parameters of QBY pneumatic diaphragm mud pump are similar to WLLDENPVMPS from the Federal Republic of Germany and MARIOWPUMPS from the United States.

Product Features of QBY Pneumatic Diaphragm Mud Pump
Four materials: aluminum alloy, cast iron, stainless steel, and engineering plastic. Diaphragm pumps use nitrile rubber, chloroprene rubber, fluororubber, and polytetrafluoroethylene diaphragms according to different liquid media. To meet the needs of different users. Since its commissioning, the QBY pneumatic diaphragm mud pump has been adopted by more than a thousand domestic units in the petroleum, chemical, electronic, ceramic, and textile systems. It is installed in various special occasions to pump media that cannot be pumped by conventional pumps, and has achieved satisfactory results.
