Multistage Pump Structure and Water Usage Diesel Engine Water Pump Set Hot Water High Pressure Boiler Feed Water Pump

Product Description

Hot Water High Pressure Boiler Feed Water Pump



Introduction:

Depon D series multistage water pump is a widely used system of high-pressure pump, run hot and cold water as a booster pumps in parallel water supply of the high-rise building, fire, boiler feed water and cooling water systems and a variety of irrigation fluid conveying. 

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≤80ºC, it is suitable for delivering mater in mine and urban water project etc.

Type DG pump can deliver clean water without solid particle or the liquid which the chemical and physical feature are similar with water, and temperature is≤105ºC, it is suitable for delivering boiler feed water or heat water.

Type DM pump can deliver the neuter mineral water which solid particles percent≤1.5% (solid Dia.<0.5mm) and other similar sewage, the temperature of the liquid is ≤80ºC, 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~150ºC.

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

Inlet pressure of pumps is less than 0.6Mpa. 


Application:
 

* Long distance water transferring
