Description
ZD series 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
* Power Plant
* Sea Water Desalination
* Clear and lightly contaminated liquids
* Commercial water supply, High building water supply
* Mining water discharge
* Supper long distance water transferring

Features and Benefits
* Greater reliability from radially split pressure casings,
ensuring overall pump concentricity and rotor alignment.
* Improved service life and tolerance to changing conditions due to
precision-cast diffusers that equalize radial loads and increase
bearing, wear ring and seal life.
* Decreased maintenance costs and longer service intervals enabled
by heavy-duty rotor with short bearing spans, which minimizes
deflection.
* Precise hydraulic configuration made possible by the modular
segmental ring diffuser design plus numerous options.
