Horizontal Ring Section Multistage Centrifugal Pump DG25-50X11 for Hot Water
Description
The Sanchang Type DG Multistage Ring Section Centrifugal Pump is a radially split, segmented casing, multistage pump designed with modular interstage components. These identical components can be assembled to produce pumps of varying numbers of stages, hydraulics, materials, and configurations to meet the customer's specific requirements.
A horizontal multistage ring section pump, can handle pressures of up to 100 bar or 1,500 psig. Aside from boiler feed applications, it can handle operations for agricultural irrigation, desalination and reverse osmosis, pressure boosting systems, natural gas processing systems, and paper mill shower water.
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 adopting precision casting and unique throttling and pressure reducing devices for auxiliary support pump vibration and noise are greatly reduced and service life is prolonged.
* Excellent hydraulic model and design, unique first stage double suction impeller, forging casting, reliable anti-abrasive materials make sure the pump with excellent NPSH, pump work steady, no noise and users do not need to add preposition pump or inrease the height of the inlet chest.
* No axial clearances when pump working and stop.
* It can change mechanical seal, bearing without disassemble the inlet/outlet pipes.
* Forging casting spare parts can save the maintenance cost
* No mechanical balancing drum, disc or similar device, which ensure pump could be applied into more wider range of application.
To meet the demands of multiple applications, which requires that pumps or parts are constructed in a specified material, the pump could be applied to transfer different kinds of liquid by customized wet parts, here followed our recommendation of main configuration:
