Brand: Worthington
Description:

The Flowserve WUJ is a vertical lineshaft multistage centrifugal pump compliant with ISO 13709 and the latest edition of API 610 (VS1) standards. Engineered for wet pit applications in refineries, power plants, water transfer, and industrial services, the WUJ delivers high reliability, efficient hydraulic performance, and long-term durability under continuous heavy-duty operation.

The Flowserve WUJ vertical turbine is a radial flow or axial flow type, multistage, heavy-duty single casing pump. It is designed for wet pit or deep well applications.

WUJ Wet Pit Pump Applications

LNG, Sewage Collection and Treatment, Water Supply and Distribution (water), Catalytic Cracking, Condensate Extraction, Crude, Product and CO2 Pipeline, Hydrotreating, Distillation (oil and gas), FPSO, Ground Water Development and Irrigation, Flood Control, Hydrocracking, Water Treatment, Dewatering and Water Supply (mining)

  • Industries:
    General Industries, Mining, Water Resources, Power Generation, Oil and Gas
  • Standards:
    API610, API682

Choice of Radial or Mixed Flow Hydraulics to best meet service requirements. Choose radial flow hydraulics for low-flow, high head applications; mixed flow hydraulics for high-flow, low head applications.

Axial Thrust Tilting Pad Bearing Configuration allows use of standard motors for high horsepower or ultra-high thrust operating conditions.

Stiff Shaft Design ensures stable operation under all service conditions.

ISO 21049/API 682 Compliant Mechanical Seal Chamber accommodates all cartridge mounted seal designs, including single, dual unpressurized or pressurized liquid or gas designs.
