High Pressure Multistage Pump Structrure Centrifugal Sump Pump For Mining Dewatering

All High Pressure Multistage Pump Structrure Centrifugal Sump Pump for Mining Dewatering pumps are strictly produced under standards of  GB/T 5657-2013 Technical specifications for centrifugal pumps ( Class Ⅲ) JB/T 1051-2006 Multistage Centrifugal Pump-Types and Basic Parameters GB/T13006-1991 Technical specifications for mixed and axial flow pumps  GB/T13007-2011 Centrifugal Pump Efficiency MT/T114-2005 Multistage Pumps for Coal Mines MD type of multistage pumps are used for transmission of clean water with solid particles size less than 0.5mm and density less than 1.5%,and temperature below 80℃,or similar physical and chemical liquid.Suitable for mining,mill and city water supply and drainage. Materials are cast iron and ductile iron for wet parts. Nomenclature: MD280-43x3 MD means wear resistant multi-stage centrifugal pump 280 means the design point of capacity of the pump is 280m3/h or 4668L/Min 43 means the design point of single-stage head is 43m 3 means the pump stage is 3 which also means it has 3 impellers.

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.
