D, MD Horizontal High Pressure Multistage Centrifugal Pump

Product Description

Application
Type D multi-stage clean water pump is a horizontal, single suction, multi-stage, segmental centrifugal pump. It is suitable for transporting clean water without solid particles or neutral liquid with physical and chemical properties similar to clean water. The medium temperature is lower than 80 ºC. It is suitable for water supply and drainage in cities, factories and mines, and farmland irrigation and drainage.
Type DL multi-stage clean water pump is a vertical, single suction, multi-stage, segmental centrifugal pump.
Type MD multistage pump is a mine wear-resistant multi-stage pump, which is based on D type pump. The flow passage parts are made of wear-resistant materials, which have the characteristics of good cavitation resistance, wear-resistant, energy-saving and long service life. It is suitable for conveying sewage containing a small amount of solid particles (particle size less than 1 mm), mine precipitation water, or neutral liquid with physical and chemical properties. The medium temperature is lower than 40 ºC. It is suitable for iron ore, coal mine and factory to discharge sewage containing impurities.

Performance range
Flow:   6.3~500 m3 /h
Head:   50~650 m
Lubrication: oil

Applications
Type SP and SPR pump are vertical, centrifugal slurry pump submerged in sump to work. They are designed for delivering abrasive, large partical and high density slurries. This pump have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties.
Type SP and SPR vertical pumps are widely used in power plants, steel, mining, metallurgy, building materials, desulfurization and other industries.
Wet parts of are make of abrasion-resistant metal or rubber.
