Boiler Feed Pumps For NPS Service


Designed to deliver de-aerated water from gas extractors (degasers) to drum separators (in BWR power plants) or to steam generators (in PWR power plants):
PEA 850-65 (for VVER-440);
PTA 3750-75 (for VVER-1000);
PEA 1650-80 (for RBMK-1500).

Multistage Segmental



PEA 850-65
Motor driven near-centreline mounted, horizontal inducer multistage segmental centrifugal pumps. Single flow impeller arrangement, with all the impellers facing the same way. Axial thrust balancing with disk and thrust ball bearing. The pump rotor is carried by the pressure-lubricated radial plain bearings. Shaft sealing: water cooled packed glands. Gear-type coupling.

Radially Split Barrel



PTA 3750-75
PTA 3750-75
Turbine driven horizontal centreline-mounted, barrel-insert multistage centrifugal pump with a withdrawable cartridge of ring-section type. Axial thrust balancing with a drum. Rotor is carried by pressure-lubricated plain bearings on both sides and an axial plain bearing on the non-drive side. Shaft sealing: slit seals with sealing condensate connections. Weld-end nozzles radial to the bottom.
PEA 1650-80
Motor driven horizontal near-centreline-mounted, barrel-insert inducer multistage centrifugal pump with a withdrawable cartridge of ring-section type. Axial thrust balancing with a drum. Rotor is carried by pressure-lubricated plain radial bearings on both sides and a hydrodynamic double thrust bearing on the non-drive side. Shaft sealing: water-cooled mechanical seals. Flanged suction and weld-end delivery nozzles radial to the top.
