Multistage pump(Horizontal Centrifugal Type)
Genernal (Multistage pump)
This type of Multistage pumps used in state for the efficient energy of the product model of efficiency projects.
It has advantages of high performance, wide scope of work, safety and smooth, low noise, long longevity and east to install and maintain. For transmission without a solid particles, not including suspension of water or physical chemistry is similar to water the rest of the liquid.
When change the material, seal type or add cooling system, it can be used for hot water, oil and corrosive media.
Structure Instruction(Multistage pump)
D type is horizontal multi-stage pump. Pump’s direction for inlet is horizontal and for outlet is vertical. To tighten the bolt will pump up the inlet part, middle part and outlet part, such as the parts become one enormous pump. We choose stages according to pump’s lift head. Pump’s rotor is a shaft with impeller, shaft sleeve, balance plate etc. The number of impeller accords to the stages. Components on shaft are combined by flat key and shaft nut. The rotor is supported by two ends of rolling bearings or sliding bearings. Bearing on the model number dissimilarity do not bear the force. Its axial force is balanced by balance plate.
Shaft seal has two types, mechanical seal and packing seal. Most D types use packing seal. When packing seal is used, it should fix on right position and has appropriate degree of tautness.
Pump is driven by motor directly through flexible coupling. From the original motives direction, a pump is clockwise rotation.
By its application scope,
the horizontal multi-stage centrifugal pump includes the following types:
D pump can be used to transport clear water containing no solid particles with a temperature lower than 80℃ or liquids with similar physical and chemical properties as clear water. It’s applicable for water supply and drainage works in mines, plants and cities.
DF pump can be used to transport corrosive liquids containing no solid particles with a temperature range of -20℃
~105℃. The pump’s allowable inlet pressure shall be less than 0.6MPa.
DY pump can be used to transport oil and petroleum products containing no solid particles with a temperature range of -20℃~105℃ and a viscosity less than 120 cP.
DG horizontal single-suction multi-stage centrifugal pump can be used to transport the clear water or other liquids with similar physical and chemical properties as clear water. It’s applicable for the water supply in low/middle/sub-high pressure boilers as well as for the high-pressure water supply and drainage in plants or cities. The temperature range of transported medium is -20℃ ~150℃ ; and the allowable inlet pressure shall be less than 0.6MPa.
In addition, our company can provide this pump series’ multi-outlet structure and function as required by customers. The user can select the pump’s material, sealing mode, structure, motor capacity and so on in a reasonable way in accordance with t he transported m edium’s name, concentration, specific gravity and working temperature, the pump’s inlet pressure and so forth.
