10 advantages of self-balancing horizontal multistage pumps VS traditional multistage pumps

1.New structure: The self-balancing horizontal multistage pump has a rotor component with symmetrically arranged impellers, so that the axial thrust generated by the positive and negative impellers during operation is basically offset by each other, eliminating the balance disc device with small gaps, high pressure drop, easy erosion, easy wear, and easy failure, breaking through the traditional structure of multistage pumps;

2.New technology: The unique throttling, pressure reducing device, and odd-numbered balancing device of the self-balancing horizontal multistage pump can also play the role of auxiliary support;

3.High efficiency and energy saving: The self-balancing horizontal multistage pump adopts an advanced hydraulic model to solve the wear and axial pulsation caused by the balance disc, so that the alignment of the impeller and the guide vane is always in an excellent state. During long-term use, it also avoids the obvious decline in efficiency of ordinary multistage pumps due to the wear of the balance disc and the forward movement of the rotor components. There is no leakage of balancing water, which reduces the volume loss, improves the overall operation efficiency of the pump, reduces the shaft power, and is 3%-12% higher than the efficiency of ordinary multistage pumps on average;

4.High reliability: The self-balancing horizontal multistage pump uses the self-balancing system to basically offset the axial force load generated during the operation of the pump, and the wear and system interference of the rotor on the pump are reduced to a very small extent. The very small residual axial force is also borne by the thrust bearing, so that the pump shaft is always in a tensile state, the stress state of the shaft is uniform, and the stress peak is greatly reduced compared with the prototype structure, thereby improving the rigidity and critical speed of the pump rotor, and significantly improving the stability and reliability of the pump rotor operation;

5.High stability: The self-balancing horizontal multistage pump has an excellent combination of symmetrical impellers and guide vanes, as well as a reasonable matching gap and a wider axial throttling design, so that the pump can still maintain extremely high stability and operating efficiency after long-term operation;

6.Good cavitation performance: The self-balancing horizontal multistage pump adopts an optimized hydraulic model and structural design, a special first-stage impeller double-suction structure, plus precision casting and wear-resistant materials, so that the pump has good anti-cavitation performance, the whole machine runs smoothly and has low noise. Users do not need to configure a pre-pump or increase the height of the water inlet tank;

7.Strong reliability of mechanical seal: Since the rotor parts of the self-balancing horizontal multistage pump have no axial movement when starting and stopping, and there is no axial pulsation when working, it has overcome the problem of poor mechanical seal reliability that has always plagued multistage pumps;

8.Easy maintenance: seals and bearings can be replaced without disassembling the pump body and inlet and outlet pipelines. General technicians can complete the replacement according to the assembly sequence and requirements of the general assembly drawing, which completely avoids the old multi-stage pump that requires professionals to adjust the axial movement size, bringing great convenience to users;

9.Low maintenance rate: reduces the number of vulnerable parts and maintenance and disassembly times, extends the service life of the product, greatly avoids a series of problems caused by excessive disassembly and assembly, and reduces maintenance costs;

10.Strong applicability: the small gap balance disc device is cancelled, which is more suitable for occasions with worse media properties than traditional multi-stage pumps.
