Detailed Product Description

     QBY cast iron The Series QBY diaphragm pump are operated with compressed air while the Series DBY electric diaphragm pumps are driven by electric motor. HAIHE's hydraulically diaphragm pump work as well as those imported from Germany or USA, suitable for pumping fluids with particles, and various liquids, which are highly viscous, volatile, corrosive or toxic, as well as colloids.

  

QBY series

1.Inlet/outlet diameter: 10-100mm
2.Flow capacity(Q): 0.8-40m³/h
3.Head: 50m
4.Suction distance: 1-5m
5.Max particle diameter:1-10mm
6.Max air pressure: 2-7kgf/cm2

    HBY cast iron diaphragm pump cancels the prevenient "O" shape ring and pole valve structure. It adopts supply air means by the three ways guide valve.

    The new designed hydraulically diaphragm pump has the larger capacity and lower start pressure and anti-stall advantage and longer life etc
