Horizontal Multi-stage centrifugal pumps according to their scope of use can be divided into the following types :

D type : Used for  transmission of water free of solid particles and temperature below 80℃ , or similar physical and chemical liquid . Suitable for mining ,mill and city water supply and drainage .

DF type : Used for transmission of corrosive liquid with temperature range for -20℃ ~105 ℃ and non-solid particles material ,sealing methods ,structure of the pump and motor model can be determined by medium , gravity ,density ,working temperature and the suction pressure .

DY type : Used for transmission of non- solid oily liquid and petroleum product with temperature range of  -20℃ ~105 ℃ and viscosity less than 120sST .

MD type : Used for transmission of neutral liquid from mining well or other similar liquid .The density and size of particles of the sewage shall be less than 1.5 % and 0.5 mm respectively . The temperature range of the sewage shall be  -20℃ ~80 ℃ .

D, DF, DY , MD-Type pump has the same performance parameters and installation size

Inlet and outlet diameter of the pump : 50-300mm(2-12inch)

Capacity Q=3.75~850m3/h

Head H=19~816m
