Horizontal Ring Section Self-Balancing Multistage Centrifugal Water Pump D280-100X7P

Description

ZD self-balancing multistage ring section centrifugal water pump is a horizontal installed single suction multistage centrifugal pump designed by comply with API610 standard, with advantages of high efficiency, wide performance, steady & safety operation, low noise, long working life, easy installation etc. It can transport the medium with solid particles (the particle size should me less than 1/4 of the impeller channel), and the pump can handling clean water, hot water, boiler feed water, corrosive liquids, oils, and abrasive medium by use different materials of construction, seal type, and external seal flushing plans.

ZD series self-balancing multistage ring section centrifugal water pump is designed to remove the mechanical balance drum, balance disc, balance socket and similar part, but achieve the balancing function by reverse circulation water pipe. Such external bypass piping is designed for water flowing into the end of the pump from the suction side, and then reversely flow back to the discharge section in the middle, which makes the water flowing from both sides of the discharge section. It will balance the axial thrust caused by the high pressure impeller from both sides and escape the mechanical wears out as well as overloaded axial force of the traditional multistage pump, and ensure the stability and endurability of the pumpset.

Design Features:

* With symmetrically arranged impeller rotor components, axial forces generated by all levels of symmetrical impellers forces offset each other and automatic balancing of huge axial thrust within pump cavity can be realized without the balance disc structure.
* Unique throtting and pressure reduction devices, odd-level balancing device.
* Using advanced hydraulic model, independent R&D enery efficient products, Good centering of impeller and guide vane channel and efficiency will not significantly drop as balancing disc wears and rotor components move forward. No leakage of balancing water reduces loss of volume and improves pump efficiency and pump efficiency is on average 2-5% higher than normal pumps.
* By canceling easy-failing balancing disc, pump reliability is greatly improved, maintenance frequency and maintenance cost are reduced.

Applications

* Boosting in General Industries of chemical process
* Boiler water feeding
* Food & beverage
* Sewage Treatment Plant
* Marine & offshore
* Fertilizers
* Power Plant
* Sea Water Desalination
* Petrochemical processing
* Clear and lightly contaminated liquids
* Commercial water supply, High building water supply
* Mining water discharge
* Supper long distance water transferring
* Handling feed water and condensate in power stations and industrial plants, Generation of pressurized water
