ZPDY Horizontal Multistage Centrifugal Pump

Since the balance multistage pump structure details:
Efficient since the multistage structure and double suction pump into single-suction multi-stage multistage structure.Is to meet user needs, accelerate the high pressure multistage pump technology development, absorbing advanced technology of similar products abroad, by the company scientific research personnel with universities, scientific research units, combined with years of design experience, the company use national recommended a new hydraulic model of high efficiency and energy saving products, according to the standard research and development of efficient high pressure multistage centrifugal pump API610 innovation products;Its typical characteristics of performance in completely eliminating the traditional in the structure is used to balance the axial force balance disc system, relying on the impeller symmetrical layout of automatic balance axial force, the innovation makes the multistage pump running with high efficiency, low noise, high efficiency area wide, wide range of performance, cavitation performance good, safe and stable operation, less wearing parts, easy installation and maintenance and operation cost greatly reduced, greatly improve the reliability, trouble-free operation time is 3 times more than ordinary pump, user maintenance cost greatly reduced, thus reducing life cycle cost of multi-stage pump.A technology leading position in the industry.Balance is the use of balance disc or drum structure of ordinary multistage pump best updated products.
Efficient self-balancing sectional centrifugal pump will have made innovations in the structure of traditional multistage centrifugal pump, cancel the ordinary multistage pump axial force balance mechanism, due to no balance device, namely no balance disc disc friction loss and no balance water back losses, so the balance of multistage pump efficiency than multistage pump with category 5 ~ 14%, and the thorough settlement of balance disc caused by the balancing device failure and balance of the disc wear or rotor killed all sorts of fault, such as greatly prolong the service life of multi-stage pump.Running over the years has shown that the self balancing multistage pump performance reached the international advanced level of similar products.
Since the balance scope of multistage pump performance parameters:
Since the balance of the multistage pump solids 2% or less, the particle size of 1.3 mm or less, medium solid concentration less than 5% wt.Temperature of 105 ℃ or less water or other liquids of physical and chemical properties similar to Yu Qingshui.Multistage pump to allow inlet pressure 0.6 MPa or less.
Self balancing multistage pump materials QT600, 304, 304 l, 304 l, 317 l, 904 l, CD4 and other material available for users to choose.Through changing the material of multistage pump (or the material of multistage pump flow components), seal form and increase the cooling system is used to transfer temperature 210 ℃ or less hot water, oil, corrosive or containing abrasive medium, etc.
Conform to API610 8 th/API610 9 th/API610 10 th standard design
According to the second edition of design API682 sealing system
Maximum flow Qmax = 1100 m3 / h
