QBY pneumatic diaphragm pump 
 I. Product Overview: 
 QBY pneumatic diaphragm pump is currently the most innovative kind of pumps, simple structure, easy to overhaul, sending fluid stability, little vibration, low noise, self-absorption capacity, transmission fluid viscosity, with pump, submersible pump, shield pump, mud pump and other transportation machinery and impurity of many advantages. Using compressed air as power source, for all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid, the liquid flow can not easily be pumping light exhaustion. The performance parameters and Federal Republic of Germany WLLDENPVMPS, the United States MARIOWPUMPS similar. Have been tens of thousands of domestic petroleum, chemical, food, medicine, electronics, ceramics, textiles, brewing, paper-making system used by a unit, placed in a variety of special occasions, for types of conventional pumps can not pump pumping the media, are made satisfactory results. 
 Diaphragm pump diaphragm is the core component, according to different media, the choice of chloroprene rubber, Teflon rubber, nitrile rubber, so as to meet different user requirements. The flow part of the pump, according to user requirements, selection of cast iron, aluminum, stainless steel and engineering plastics, such as different materials.
