D series mine pumps are horizontal multi-stage Centrifugal pumps,they are used for coal mine,factories and cities. The temperrature of pumped medium are not more than 80℃.the series pumps Are accoding to standard MT114-2005 (Technical Spectfications for coal mine  pumps).

D series mine pumps with YB motor are used under the mine well,but not used to dig operating occasion.the pumps with YBK motor Are used to dig operating occasion.with Y motor not used under the mine well.
MD series wear-resistant multistage centrifugal Pump, it's over current components are wearing material, mainly for conveying Solid particles in the neutral mine water (grain size less than 0.5 mm), and Similar to other sewage.

MDF series wear resistance and corrosion resistance multistage centrifugal Pump, it's over current components are used in wear-resistant Corrosion-resistant material, mainly used for conveying solid particles content Is not more than 1.5%, corrosive coal mine water (particle size less than 0.5 Mm), and similar to other sewage. Wear resistance of the material, according to The user's requirements.

the series pumps are used in coal mine by MT/T 114-2005 (Technical Spectfications for coal mine  pumps)Standard to Organize production. the highest temperature of the conveying fluid is not more Than 80℃, which is suitable for the underground Drainage and factories, the city water supply and so on.

the series mine pumps with YB motor are used under the mine well,but not used to dig operating occasion.the pumps with YBK motor Are used to dig operating occasion.with Y motor not used under the mine well.
