Horizontal Ring Section Self-Balancing Multistage Centrifugal Water
Pump ZDF25-50X8P
Description
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.
* 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
* Sea Water Desalination
* Clear and lightly contaminated liquids
* Commercial water supply, High building water supply
* Mining water discharge
* Supper long distance water transferring
