Pump for Water (D/DG/DF/DY/DM25-50X4)

1.General

The serial pump is multi-stage section centrifugal pump, the excellent hydraulic models are high-efficiency,
energy-saving, and have wide performance range, operating safety&steady, low noise, long life and installing & repairing is very convenient etc. It can deliver heat water oil,corrosive or wearable medium by changing the materal, seal or adding cooling system.

Type D pump can deliver water withput solid particle or the liquid which the chemical and physical feature are similar with water and temperture is ≤80ºC, it is suitsble for delivering mater in mine and urban water project etc.

Type DG pump can deliver clena water without solid particle or the liquid which the chemical and physical feature are similar with water, and temerature is ≤150C,It is suitable for delivering boiler feed water or heat water in factory and medium and low pressure boiler water supply etc.

Type DM pump can deliver the neuter mineral water which solid particles percent ≤1.5%(solid Dia.it is suitable for steel works,mines.cities projects etc.

Type DF pump can deliver the corrosive liquid without solid particle, which temperature is from -20ºC to 150ºC.

Type DY pump deliver oil products without solid grain, ciscosity ≤120ct, range of temperature is from -20ºC to 150ºC.
