Flowserve-Worthington-Double Case Pumps - WUC

Double Case Pumps - WUC

BRAND: Worthington

Compliant with ISO 13709/API 610 (VS6), the Flowserve WUC vertical turbine is a radial flow or axial flow type, multistage, heavy-duty double casing pump. It is designed for continuous un-spared duty at a variety of high-pressure services, operating at temperature extremes and handling difficult liquids.

  • Up to 20 stages
  • Suction diameters from 2" to 24" and discharge diameters from 2" to 16"
Features & Benefits
  • WUC is the ultimate double case vertical pump
  • The WUC covers the highly engineered specialty end of Flowserve's family of double casing vertical pumps
  • This pump line is based on a modular system, thus providing maximum design and operating flexibility
  • This is combined with specific design features, including stiff shaft construction, a self-contained axial thrust bearing housing and pressure containing parts certified to various international standards
  • This makes the WUC to the pump of choice for most critical applications where space considerations or marginal NPSHa values preclude the use of a horizontal pump
  • Special designed WUC pumps are capable to handle cryogenic liquids (like Methane, Ethylene, LNG, LPG, etc.) down to -200°C (-328°F)
  • For exceptionally low NPSHa applications the WUC can be equipped with an inducer; double suction impellers are available for selected hydraulics
  • The full API 610 compliant WUC will be engineered to customer specifications, is designed to meet all material requirements and will perfectly meet the selected service conditions
