D. DG and DL multi-stage centrifugal pumps

D. DG type multi-stage centrifugal pump is a horizontal single suction multi-stage segmental centrifugal pump. According to the different materials used in the pump, it can transport clean water (containing less than 1% impurities) and other corrosive liquids with physical properties similar to clean water. The medium temperature transported by the ordinary D.DG type pump is not much than 80 ℃, which is suitable for water supply in mines, factories, and cities; Special material D and DG pumps are suitable for transporting neutral or corrosive, clean or containing small amounts of solid particles in industries such as petroleum, chemical, power, metallurgy, pharmaceuticals, and environmental protection.
