The Ultimate Double CasingVertical PumpThe model WUC covers thehighly engineered specialtyend of the Flowserve family of
double casing vertical pumps.The pump line is based on amodular system, thus providingmaximum design and operatingflexibility. This is combinedwith specific design features,including stiff shaft construc-tion, a self-contained axialthrust bearing housing andpressure containing partscertified to various internationalstandards. Altogether, thismakes the WUC the pumpof choice for the most criticalapplications where space con-siderations or marginal NPSHAvalues preclude the use of ahorizontal multistage pump.
Choice of Hydraulic Designto best meet servicerequirements Radial flow hydraulics for low
flow, high head applications,

Axial Thrust TiltingPad Bearing
The Flowserve WUC verticalturbine is a radial flow or axialflow type, multistage, heavy-dutydouble casing pump. It isdesigned for continuous un-
spared duty at a variety of highpressure services, operatingat temperature extremes andhandling difficult liquids.
Designed to InternationalStandards API 610, latest edition ASME Sections VIII and IX German Pressure Vessel
Association (AD) British Standard BS 5500 Compliance with Pressure
Equipment Directive 97/23/EC
Flanged Spacer TypeCoupling permits easymaintenance of thrustbearings and mechanicalseals without disturbing
or removing driver.
Separate Axial ThrustBearing Assemblydesigned to withstandtotal hydraulic thrustand rotor weight Self-contained oil
lubricated, anti-frictionbearings for standardapplications

Coffer Dam SystemThis highly engineered designfor cryogenic applicationsprovides for a gas barrierbetween the pumped fluid and
the mechanical seal. The seal,with back-to-back seal facearrangement, results in the innerseal being subjected only to gasat 2 bar (30 psi) above suctionpressure. Therefore, no icing canoccur and the barrier fluid can bepressurized with nitrogen at lowpressure. Due to the low pressure
and the ice-free seal environment,standard mechanical seals canbe used.
InducerA special axial flow pumpingdevice, an inducer providessignificant improvement insuction performance by reducingpump NPSHR. This results in areduced suction barrel lengthand a more compact, lessexpensive installation. A specialinducer design reduces the back-flow and guarantees trouble-freeoperation over a wide flow range.
