Product Description
Boiler Feed High Head Low Flow High Speed Centrifugal Pump
Boiler feed water service is a textbook low-flow, high-head application. The pump must overcome drum pressure plus piping losses while delivering only a modest flow, so a machine that stays efficient far from its best efficiency point is essential. This high head low flow duty is precisely what an integrally geared pump is designed for.
Rated at 442 m TDH, this boiler feed centrifugal pump is engineered as an API 610 OH6 vertical unit. The precision gearbox raises speed to deliver the head at low flow, and a low-NPSHr impeller protects the pump against the cavitation risk that comes with hot BFW.
The vertical design keeps the suction nozzle low, maximizing available NPSH and simplifying feed line routing. A tandem seal with a Plan 32 flush manages the temperature and ensures clean liquid at the seal faces even in hot, high pressure service.
Produced under ISO 9001 control, each unit is dynamically balanced, hydro-tested and performance-verified on a calibrated rig. Full documentation is issued with every pump, giving power and process plants confidence in continuity of feed water supply.

Frequently Asked Questions
Q: Why is the TDH so high with low flow?
A: Boiler feed must overcome drum pressure plus line losses at modest flow; an integrally geared pump delivers that high head efficiently.
Q: How is cavitation prevented?
A: A low-NPSHr inducer and a vertical suction-near-floor layout maximize available NPSH in hot feed water.
Q: What seal arrangement is used?
A: A tandem seal with an API Plan 32 clean water flush keeps the seal faces cool and clean.
Q: Can it match my boiler duty point?
A: Yes. Provide flow, TDH, temperature and fluid; our engineers will confirm the trim and provide a quote.
