Circulating Water Pump for Power Plant Cooling Systems

Application: Type DG boiler feed pumps are used for feeding to middle and high pressure boiler or for pumping other high pressure clean water. The highest applied temperature of middle pressure boiler feed pumps is up to105℃and one of high pressure boiler feed pumps is up to160℃.   Flow range: 32.4-155m³/hr(middle pressure pumps) 200-450m³/hr(high pressure pumps) Total head range: 367-603m(middle pressure pumps) 1520-1975m(high pressure pumps)     Structure: DG pumps are single-casing,multi-stage centrifugal pump with ring section body.Suction nozzle of type DG 36-50 pump is arranged horizontally and discharge nozzle is arranged vertically up.Suction and discharge nozzles of other type pumps are arranged bertically up,Suction, middle stage and discharge casing are rigidly held together by tie bolts. The joints between these casing are sea led by means of metal-to-metal contact.Typy DG 36-50 pump and its motor have common baseplate, but other type DG pumps and motors don`t have common…
