Modular DesignThe modular design of theWXH pump offers hydraulicflexibility within the pump,enabling Flowserve toprecisely match pumpperformance to desiredoperating conditions. Anadditional benefit isreduced leadtime fromorder to shipment.

Applications• Power generation

– Boiler feedwater– Desalination– Descaling

• Chemical processing• Oil production and

transportation• Non-hydrocarbon

services in refineries

Complementary Pump DesignsType WXH pumps maybe used with Flowservepumps of the followingdesigns:• Multistage barrel pumps• Vertical pumps• Single stage pumps• Frame mounted, end

suction pumps

Type WXHHorizontal, radially split, highpressure, ring section pump

Diffuser Pump BenefitsAvailable in various sizes,hydraulics and material combi-nations, Type WXH pumps maybe used in a wide range ofapplications. They are particularlywell suited for boiler feedwateron large industrial boilers andin combined cycle plantswhere severe cycling operationis commonplace.

The near perfect balance ofradial and hydraulic forces inthis diffuser-type pump providessignificant performance andenergy efficient benefits.• The hydraulics provide a wide

range of overall efficiencywithin each pump size. Largeeye single suction or alternatedouble suction first stageimpellers are utilized dependingupon NPSH available ona given application.

• Precision, investment castdiffusers and return channelhydraulic passages ensurehigh efficiency.

Operating Parameters• Flows to 1160 m3/h (5100 gpm)• Heads to 2750 m (9000 ft)• Temperatures to 200˚C (400˚F)• Pressures to 310 bar (4500 psi)

Superior Interstage O-Ring ArrangementUnique design does not placeinterstage O-rings in shear duringassembly. This removes the possibility of O-ring damageduring routine maintenance.

Bearing ConfigurationsProven bearing design optionsare engineered to fit the servicein which the pump is employed.

Materials TechnologyIndustry-proven and laboratory-tested materials contribute toconstruction that will last the lifeof the facility.

Easier MaintenanceA separate sub-base allowsfaster removal and betterrealignment while facilitatingmaintenance.

No Pre-WarmingMechanical design considersthermal stress gradients. Rotordesign prevents binding due tothermal transients.

First Stage DesignsEither single- or double-suction pumps havebeen expertly engineeredto ensure reliable per-formance throughout thevarious operating ranges.

Optimized HydraulicPerformanceTo increase efficiencyand reduce operatingexpense, computationalfluid dynamics (CFD) has been applied topump design.

Axial Balance DeviceStandard flanged balancedrum or optionalstraight balance drum is available to suit the application. Runningclearances are serratedto reduce drum leakageand optimize efficiency.

Nozzle ConstructionFlowserve nozzles areconstructed fromchrome steel, exceedingthe industry standard.The user benefits fromlonger life and higherstrength.

Precision CastingsOptimum efficiency andrepeatability of hydraulic performance are achievedthrough the use of precisioninvestment castings forimpellers and diffuser-returnchannel passages.

Seal ChambersSeal chambers are sized toaccept single, double and tandem mechanical seals.
