The D series Multistage Ring Section Centrifugal Stainless Steel Water Pump is a utility-grade, high-pressure, ring section pump with heavy duty, segmental ring, diffuser design. Axial thrust balance device with stacked rotor construction. Suitable for boiler feed pump and high building, long distance water transferring.

Structure Design

* 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.

High operating reliability
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.
