Product description

QBY series pneumatic diaphragm pump is a new type of conveying machinery. The compressed air of air compressor is used as power source. It can absorb all kinds of corrosive liquids, granular liquids, high viscosity, volatile, flammable and highly toxic liquids. Its performance parameters are similar to WLLDENPVMPS of Federal Germany and MARIOWPUMPS of the United States. At present, our factory has formed a series of production with eight specifications: 10 mm (3/8"), 15 mm (1/2", 25 mm (1"), 40 mm (1/2", 50 mm (2"), 1/2", 80 mm (3), 100 mm (4". Three kinds of materials, aluminum alloy, cast iron and stainless steel. The diaphragm pump adopts NBR, chloroprene rubber, fluorine rubber and PTFE according to different liquid media. To meet the needs of different users. Since its commissioning, the pump has been adopted by more than 1,000 petroleum, chemical, electronic, ceramic, textile, paint and pharmaceutical machinery units in China. It has been placed in special occasions to pump medium that can not be pumped by conventional pumps and to replace ideal products of gear pumps. Satisfactory results have been obtained.
