Nuclear Pumps - RLIJ

BRAND: Flowserve

This ASME Section lll, Class 2 and 3 pump is designed for chemical and volume control system charge service with boiling water reactors (BWR), pressurized water reactors (PWR), and pressurized heavy-water reactors (PHWR).

Product Highlights

Industries

  • Power

Industry Sectors

  • Nuclear

Standards

  • ASME Section III, Class 2 and 3

Operating Parameters

  • Flows to 45 m3/h (200 gpm)
  • Heads to 2000 m (6560 ft)
  • Pressures to 235 bar (3410 psi)
  • Temperatures to 130°C (300°F)
  • Speeds to 6300 rpm

Design Range

Size Range: 2" and 2.5" discharge

Features and Benefits

  • Precision Cast Diffusers minimize bearing spans, thereby increasing pump reliability and efficiency.
  • Suction and Discharge Connections are located on the top of the barrel and may be supplied with flanged or weld end design to suit installation requirements.
  • Forged and Hardened Stainless Steel Balance Drum is generously sized to completely unload the thrust bearing at all operating points
  • Self-Aligning, Double-Acting Tilt-Pad Thrust Bearings are conservatively rated to carry axial loads that may be encountered during transient operating conditions.
  • Precision Cast Tandem Impellers are positively locked and keyed to the shaft.
  • Serrated and hard faced Impeller Running Fits reduce the effects of rotor contact during system upsets or turning gear operation.

Configurations

Horizontal multistage, barrel, radial split
