Water Drainage Multi-stage Coal Mine Pump

MD type of coal mine 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:

MD46-50x8

MD means wear resistant multi-stage centrifugal pump

46 means the design point of capacity of the pump is 46 m3/h or 766.8L/Min

50 means the design point of single-stage head is 50m

8 means the pump stage is 8 which also means it has 8 impellers.

MA certifaction:

As 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.

We can offer installation training for our distriction agent.

Packing: Plywood case or as required.

Shipping: According to the Price terms
