Suction Flowrate Prediction Model for a Boiler Feed Pump

Pump & System Curve Data for Centrifugal Pump Selection

pump operation completely unaffected by water temperature or density. Some pump curves show PSI vs GPM or PSI vs lbs./hr. These curves are not general, but specific, and require definition in terms of water temperature and density. PSI curves are sometimes used for boiler feed pump description but sho uld not be used in selecting pumps for Heating-

Boiler Feed Pump | Carver Pump

Boiler feed pumps discharge water into a boiler drum. In turn, the boiler heats up the water and turns it into steam. In functions like these, boiler feed pumps must be strong enough to handle varying temperatures to function well. Aside from temperature, boiler feed pumps need to handle different feedwater flows and intense water pressure.
