Special-purpose pumps
| Special-purpose pumps are applied in special systems of NPP units with reactors VVER-1000 PBMK (coolant makeup system, aftercooling system, sprinkler system, fire fighting system).
Special purpose pumps are centrifugal, multistage or with double-entry impeller, horizontal, with forged or cast casing. Casing material - austenitic steel. As a pump drive it is used electric motor. Motor and pump drive are connected by gear-type or flexible plate coupling. Rotor pump shaft is sealed by mechanical end seal. Axial force relief is compensated in most cases by hydraulic discharging device. |  |
