1.About Multistage boiler feed water pump:
      Model QD (G) pump is a horizontal multistage centrifugal pump and suitable for transporting pure water (with the contained foreign matters' content less than l % and graininess less than 0. 1mm) and other liquids of both physical and chemical natures similar to those of pure water.

QD (G) model middle and low pressure boiler water supply pump is applicable to transport medium with temperature of not higher than 120ºC, and is also applicable for small boiler water supply or transporting medium similar to hotwater.

   QDG model hypo-high
pressure boiler water supply pump is applicable to transport medium with 
temperature of not higher than 180ºC, and is also applicable for small boiler water supply or transporting medium similar to hot water.

2.The structure of high discharge pressure multistage pump


1)Stator portion
 
      Consists of suck-in section. middle-section, spitting section, guide vane, packing etc., which are linked together with a take-up bolt. with both suck-in and spitting mouths vertically upward.
 
2)Rotor portion
 
      Consists of a shaft, impeller, balancing disk, muff etc. Parts.
 
3)Bearing portion
 
      The whole rotor is supported by the roller bearings orsliding bearings on both ends of the shaft and the bearingsare lubricated with grease or 20# engin oil.
 
4)Cooling and seal of Multistage boiler feed water pump
 
      The joint-part between suction section, intermediatesection and discharge section
with be coated with molybdenum disulfide lubricating grease as seal. Rotor and fixed parts will be sealed by seal ring, guide-vane jacket and packing. The packing tensile degree of shaft seal should be proper and seep should be feasible dip by dip Unload run should be forbid. The seal ring and guide vane jacket should be replaced if they are too worn to be used any more and even do harm to pump work. There is spare shaft sleeve near shaft seal to protect shaft of pump.
