Self balancing multi-stage centrifugal pump:
Adopting advanced hydraulic models and independently developing high-efficiency and energy-saving products; Due to the absence of wear and axial pulsation on the balance plate of the self balancing symmetrical multi-stage pump rotor, the alignment between the impeller and guide vanes is always in a better state, and the efficiency will not significantly decrease with the wear of the balance plate and the forward movement of the rotor components like in ordinary multi-stage pump structures; And there is no leakage of balancing water, reducing volume loss, improving the overall operating efficiency of the pump, reducing shaft power, and averaging 2% -3% higher efficiency than ordinary multi-stage pumps

The ZD type self balancing symmetrical horizontal multi-stage pump is a high-efficiency and high-pressure multi-stage centrifugal pump product developed in accordance with the API610 standard to meet user needs and accelerate the development of high-pressure multi-stage pump technology. It adopts advanced technology from similar foreign products combined with our company's many years of design experience, and uses the hydraulic model of high-efficiency energy-saving products recommended by the country; Leading in technology within the industry. It has the advantages of wide high-efficiency zone, wide performance range, good cavitation performance, few vulnerable parts, and easy installation and maintenance. The reliability is greatly improved, and the fault free operation time is more than three times that of ordinary pumps. The maintenance cost for users is greatly reduced, thereby reducing the life cycle cost of the pump. The high-pressure self balancing segmental centrifugal pump innovates the structural form of traditional multi-stage centrifugal pumps by eliminating the axial force balance mechanism of multi-stage centrifugal pumps. It is a better alternative to D and DG type multi-stage centrifugal pumps that use balance disks or balance drum structures. Due to the absence of a balancing device, which includes both disc friction loss and reflux loss, the pump efficiency is 5-14% higher than that of multi-stage pumps of the same category. At the same time, it completely solves various faults caused by the failure of the balancing device, such as wear and tear of the balancing disc and its seat or rotor biting, greatly extending the service life of the pump. Years of operation have proven that the performance of this product has reached the advanced level of similar international products.
