    Pump SupplierTo The World

    Flowserve is the

    driving force in the

    global industrial

    pump marketplace.

    No other pump

    company in the

    world has the

    depth or breadth

    of expertise in

    the successful

    application of

    pre-engineered,

    engineered and

    special purpose

    pumps and

    systems.

    Pumping SolutionsFlowserve is providing pumpingsolutions which permit cus-tomers to continuously improveproductivity, profitability and

    pumping system reliability.

    Market FocusedCustomer SupportProduct and industry specialistsdevelop effective proposals andsolutions directed toward marketand customer preferences.They offer technical advice andassistance throughout eachstage of the product life cycle,beginning with the inquiry.

    Dynamic TechnologiesFlowserve is without peer in thedevelopment and application ofpump technology, including: Hydraulic engineering

    Mechanical design Materials science Intelligent pumping Manufacturing technology

    Broad Product LinesFlowserve offers a wide rangeof complementary pump types,from pre-engineered processpumps, to highly engineeredand special purpose pumpsand systems. Pumps are builtto recognized global standardsand customer specifications.

    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,

    and featuring: Stage casings with separate

    diffusers Casings retained by

    tie-bolts Interstage bushings and

    sleeves Mixed flow hydraulics

    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.
