Start And Shutdown Pumps For Nuclear Power Stations |
Used as auxiliary boiler feed pumps for delivering feedwater from deaerator to steam generator during heating-up and cool-down conditions of the primary circuit of NPS with a pressurized water reactor.
TsN 150-90 pumps are used for delivering condensate from storage tanks to steam generator in VVER-1000 PWR nuclear power
stations.

Radially Split Barrel
|
Motor driven near-centreline mounted, horizontal multistage radially split diffuser barrel-casing centrifugal pumps with a withdrawable cartridge of ring-section type. Single flow impeller arrangement, with all the impellers facing the same way. Rotor axial thrust is compensated by balance disc.
The pump rotor is carried by the oil-ring lubricated plain bearings. Shaft sealing: mecha-nical
seals.
