The company QBY series pneumatic diaphragm pump is a new type of transport machinery, is currently the most innovative of a pump. Using compressed air as power source, for all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid, can be drawn light exhaustion. The performance parameters and Federal Republic of Germany WLLDENPVMPS, the United States MARIOWPUMPS similar. 
 Series production company currently has a total of eight standard diameter: φ10mm (3 / 8 '), φ15mm (1 / 2'), φ25mm (1 '), φ40mm (11 / 2'), φ50mm (2 '), φ65mm (21 / 2 '), φ80mm (3'), φ100mm (4 '). Four materials: aluminum, cast iron, stainless steel, engineering plastics. Diaphragm pumps were used according to the different liquids NBR, neoprene, Viton, PTFE diaphragm. To meet the needs of different users. 
 The pump has been put into operation since 1986, has been more than a thousand domestic petroleum, chemical, electronics, ceramics, textile system unit used, placed in a variety of special occasions, for types of conventional pumps can not pump pumping the media, are made satisfactory results.
