This ASME Section lll, Class 1 is designed for primary coolant, reactor re-circulation and primary heat transport service with Boiling Water Reactors (BWR), Pressurized Water Reactors (PWR), and Pressurized Heavy-Water Reactors (PHWR).
One-piece pump casing features a double volute design for BWR and PHWR applications and a diffuser with a torus-type casing for PWR service.
Upgraded rotating element uses a one-piece welded shaft-impeller-journal assembly. This fully machined assembly is balanced as a single rotating unit.
Hydrostatic-pressurized radial bearing operates submerged in radioactive system water at loop temperature of approximately 300°C (580°F) with no external source of cooling water.
