High efficient multistage centrifugal water pumps are end suction, horizontal centrifugal pumps with closed impellers and diffusers. These multistage pumps are only suitable for clean or slightly contaminated (max. 20 mg/dm³), low viscosity fluids including fresh water and sea water.
Feature:
1.Type D pump can deliver water without solid particle or the liquid which the chemical and physical feature are similar with water and temperature is ≤ 80℃,it is suitable for delivering water in mine and urban water project etc.
2.Type DG pump can deliver clean water without solid particle or the liquid which chemical and physical feature are similar with water, and temperature is ≤ 105℃,it is suitable for delivering boiler feed water or heat water.
3.The DM pump can deliver the neuter mineral water which solid particles percent ≤ 1.5%(solids Dia < 0.5mm)and other similar sewage, the temperature of liquids is ≤80℃.It is suitable for steel works, mines, cities projects etc.
4.The DF pump can deliver the corrosive liquid without solid particle, which temperature is from -20℃~150℃
5.The DY pump deliver oil or oil products with solid grain, viscosity ≤120ct,range of temperature is from -20℃~150℃
