This series of high pressure multistage pump are horizontal single suction multistage centrifugal pumps, which adopt the hydraulic model of high efficiency and energy saving products recommended by the state. The utility model has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long service life, convenient installation and maintenance, etc. It can be used to transport clear water without solid particles (Abrasives), suspended solids or other liquids with physical and chemical properties similar to clear water. It can also be used to transport hot water, oil, corrosive or wear-resistant media by changing the material of the pump (or the material of the overflow part of the pump), sealing form and increasing the cooling system.
The high pressure multistage pump is mainly divided into the following types according to its scope of use:
1) DF type: the DF high pressure multistage pump is used for conveying corrosive liquid without solid particles and with a temperature of - 20 ℃ ~ 105 ℃, and the allowable pressure at the pump inlet is less than 0.6MPa. According to the name, concentration, specific gravity, operating temperature and pump inlet pressure of the conveying medium, the user can reasonably select the material, sealing form, pump structure and determine the capacity of the motor.
2) D-type: D-type high pressure multistage pump is used to transport clear water without solid particles and temperature lower than 80 ℃ or liquid with physical and chemical properties similar to clear water. It is suitable for water supply and drainage engineering in mines, factories and cities.
3)DG high pressure multistage pump is used for transfer hot water120 degree，highpressure boiler multistage pump.
