General
          D-type pump is a single-suction multistage sectional centrifugal pump suitable for water supply and drainage in mines ,factories and cities. It is used to convey fresh water without solid particles, abrasive or suspended matters, or other liquids having similar physicochemical properties to fresh water. The temperature of the liquid to be conveyed is -20~~80℃.
          MD-type single-suction multistage wear-resistant pump is formed by changing the material based on the original D-type pump, suitable for neutral mineral water (particle size less than 0.5mm) with solid particles content not more than 1.5%and other similar sewage , the temperature of the medium to be conveyed is not higher than 80℃, suitable for steel works, mine drainage, sewage conveying and other occasions. It has the same performance parameters and overall dimensions as D-type pump.
