Vertical annular casing pump with forged or cast pressure boundary and diffuser. Applications are Core flooding, emergency cooling and residual heat removal systems, ancillary systems, acid feed system and low-pressure injection system, component cooling water systems.
Quick replacement and maintenance: ■ Pull-out design of pump internals ■ Mechanical seal in cartridge design
Reduced susceptance to failure: ■ Elimination of ancillary systems (cooling, lubrication, instrumentation & control, piping, tanks, etc.)
High safety: ■ Symmetrically forged casing contour for highest strength and 100% NDE testing
Insensitive to dirt particles and short-time dry running
