Double Flow Axially / Radially Split PD Series Pumps
The boiler feed booster pumps are installed upstream of boiler feed pumps with the pumping temperature of max. 165°C at the power units in TPS's to ensure the necessary suction head (a greater NPSH available) for the main pump, so that it should not cavitate in any operating conditions.
PD 650-150: Motor-driven horizontal single-stage axially split volute casing centrifugal pumps with a double entry radial impeller. Pump nozzles oriented horizontally to the opposite sides. The pump rotor is carried by the oil-ring lubricated plain bearings. Shaft sealing: packed glands.
