Product Description
MD type of multi-stage pumps are 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 0.5mm respectively.The temperature range of the sewage shall be -20℃~80℃.
Wet parts are wear-resistant cast iron ,ductile iron or as required.
Nomenclature:
MD25-30x2
MD means wear resistant multi-stage centrifugal pump
25 means the design point of capacity of the pump is 25m3/h
30 means the design point of single-stage head is 30m
2 means the pump stage is 2 which also means it has 2 impellers.

Our ServicesAs a professnional manufacturer of multi-stage centrifugal pumps,we can produce different types of pump according to the applicaiton.We have D,DF,DY,MD,DG series of traditional multi-stage pump; D(P), DF(P), DY(P), MD(P) DG(P)series of self balancing multi-stage pump.
Usually D/D(P) types of multi-stage pump 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/DF(P) types of multi-stage pump used for transmission of corrosive liquid with remperature range of -20℃ ~ 105℃ and non-solid particles.We will produce according to the gravity,density,working temperature and the suction pressure of the fluid.
DY/DY(P) types of multi-stage pump used for transmission of non-solid oily liquid and petroleum product with temperature range of -20℃ ~ 105℃ and viscosity less than 120cst.
MD/MD(P) types of multi-stage pump used for transmission of neutral liquid from mining well or other similar liquid.The density and size of the particles of the sewage shall be less than 1.5% and 0.5mm respectively.The temperature range of the sewage shall be -20℃ ~ 80℃.
DG/DG(P) types of multi-stage pump used for low and medium pressure hot water transmission,also named as boiler feed pump.Temperature ranges from -20℃ ~ 150℃.
All the max. suction pressure shall be 0.6Mpa.
