Multistage centrifugal water pump to mine 

D、DG、DF、DY、MD self balanced multistage centrifugal pumps are used to transport solid particles of no more than 2% (particle size is less than 1mm), and medium solid concentration is less than 5% wt. Water with temperature ≤ 105 ℃ or other liquids with physical and chemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media with temperature ≤ 210 ℃ by changing the material of pump (or the material of pump overflow parts), sealing form and adding cooling system.

Advantages of self balancd multistage centrifugal water pump

1. The rotor part is arranged symmetrically, so that the axial thrust generated by the positive and negative impellers in operation is basically offset each other, so that it does not need the balance disc device with small clearance, high pressure drop, easy to wash, easy to wear and easy to break down.
2. The unique throttling and decompression device further reduces the leakage of medium from high pressure side to low pressure side, and the volume efficiency of the pump is high.
3. With the advanced hydraulic model, because the pump rotor has no wear and axial pulsation of the balance plate, the impeller and guide vane are always in the best neutral position, and the efficiency will not be significantly reduced as the ordinary multistage pump structure with the wear of the balance plate and the forward movement of the rotor part; without the leakage of the balance water, the volume loss is reduced, and the operation efficiency of the pump is improved and reduced as a whole Shaft power is 2% - 3% higher than the average efficiency of ordinary multistage pump.
4. The axial force load of self phase balance reduces the wear and system interference of the pump to the minimum, and a small part of the residual axial force is borne by the thrust bearing, so that the pump shaft is always in the state of tension, the stress state of the shaft is uniform, and the stress peak value is greatly reduced compared with the prototype structure, thus improving the rigidity and critical speed of the pump rotor, and improving the stability and reliability of the pump rotor operation.
5. The optimized hydraulic model and structure design, precision casting, reliable wear-resistant material, good anti cavitation performance of the pump, stable operation of the whole machine, low noise.
6. When the pump starts and stops, there is no axial movement of the rotor parts, and there is no axial pulsation when it works, which overcomes the problem of poor mechanical seal reliability that has been plagued by the multistage pump.
7. The quick disassembly design of the equipment allows the water pump to replace the seal and bearing without disassembling the pump body and the inlet and outlet pipelines. There is no balance plate and other vulnerable parts in the pump, saving overhaul and inspection time.

We had two projects in 2017 and in 2019, which is for the undermine dewatering system, and for the reopening in the near future. According to the working conditions and medium, we recommend the self balanced multistage centrifugal water pump, and select the stainless steel 304 and 316 material for wearing parts. So we finish the project well.
