Self Balancing Multistage Pump

Self Balancing Multistage Pump

The ZD self-balancing multi-stage pump is an advanced product with high efficiency, energy saving and long service life designed to meet the needs of users.

The use of foreign high-efficiency and energy-saving water conservancy models has changed the design of traditional multi-stage pumps with balancing devices and accelerated the technological development of high-pressure multi-stage pumps.

R&D and manufacturing according to API610 standard, occupying a leading position in technology in the industry.

It has the characteristics of wide high efficiency zone, wide performance range, good cavitation performance, safe and stable operation, low noise, few wearing parts, and convenient installation and maintenance.

The ZD type high-efficiency energy-saving self-balancing multi-stage pump reforms and innovates the traditional structure, cancels the axial force balance mechanism of the traditional multi-stage centrifugal pump, and cancels the balance disc device.

It is the best replacement product of D and DG multi-stage centrifugal pumps.

ZD type high-efficiency energy-saving self-balancing multi-stage pump has no disc friction loss of balance disc and no return loss of balance water, so the pump efficiency is increased by 5%-14% compared with the same type of multi-stage pump.

The shaft power of the pump is reduced without friction on the balance plate,

So as to achieve the effect of energy saving, the power consumption of the pump during operation is about 3% less than that of the same type of multi-stage pump.

At the same time, it completely solves various failures such as the wear of the balance disc and the balance ring and the rotor seizure caused by the failure of the balance device. Its design extends the service life of the pump.

The trouble-free operation time is more than 3 times that of ordinary pumps, and user maintenance costs are greatly reduced, thereby reducing the life cycle cost of the pump.

Years of operation have proved that the performance of this product has reached the international advanced level of similar products.

It can be used to transport clear water with particle content ≤1.5%, particles ≤1.3mm, temperature ≤105℃ or other liquids with physical and chemical properties similar to clear water.

It can also be used to transport hot water, oil, corrosive or abrasive media, etc., with a temperature ≤ 225°C by changing the material, structure, and sealing form of the pump and adding a cooling system.

There are HT200, QT600, ZG, 304, 304L, 316, 316L, 317L, 904L, CD4 and other materials for customers to choose from.

The performance parameters are as follows:

Flow rate: 3.7m³/h~ 1350m³/h,
