High Pressure Belt Driven Diesel Water Pump |
Multistage pump application
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 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 105ºC, and is also applicable for small boiler
water supply or transporting medium similar to hot water.
Multistage pump description:
This serial pump is multistage section centrifugal pump, the excellent hydraulic models
are highe fficiency, energysaving, 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 wearalbe medium by changing the material, seal or adding cooling system.
1. The multistage pump can deliver the neuter mineral water which solid particles percent≤ 1.5%(solid Dia, < 0.5mm) and other similar sewage,
2.Temperature of the liquid is ≤ 80° C. It is suitable for steel works, mines, cities projects etc.
This kind pump can deliver the corrosive liquid without solid particle, which temperature is from -20° C-150° C
The multistage pump deliver oil or oil products without solid grain, viscosity ≤ 120ct, range of temperature is from -20 ° C to 150 ° C
More detailed information of the Multistage pump:
For this series horizontal multistage centrifugal pump, both ends of it are supported, the
casing portion is in a sectional form. it is connected to and actuated by a motor via a resilient
clutch and the rotating direction of it. viewing from the actuating end. is clockwise.
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.
Rotor portion
Consists of a shaft, impeller, balancing disk, muff etc. Parts.
Bearing portion
The whole rotor is supported by the roller bearings or
sliding bearings on both ends of the shaft and the bearings are lubricated with grease or 20# engine oil.
Cooling and seal of pump
The joint-part between suction section, intermediate
section 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.
