Comprehensive Product LineFlowserve manufactures one ofthe worlds most comprehensivelines of vertical turbine, mixedand axial flow pumps. With more
than 300 bowl and impellermedium and high capacitydesigns, Flowserve providesunsurpassed hydraulic coverage,with specific speeds from 1500to 5500, to ensure the bestpump selection for a wide varietyof services.
Offered in a wide range ofconfigurations, construction andmaterials, Flowserve VTP pumpsare typically installed in a wet pit
or deep well where NPSH avail-able is usually not a problem.When a wet well is not availableor there is insufficient NPSHavailable, the VTP pump with lowNPSH impellers can be mountedin a suction barrel or can, whichserves as the holding vessel forthe liquid.
Models AvailableFlowserve offers severalmodels to best suit applicationneeds, including: VTP for general industrial
service VTP double casing with
optional API 610, latestedition design
VTP-WUC double casing toAPI 610, latest edition, ASMECode Section VIII and IX,German Pressure VesselAssociation (AD) and otherinternational standards
VTP engineered models forcapacities through 160 000m3/h (750 000 gpm)
Typical Applications Municipal water Irrigation General industrial Snow making Power generation Oil and gas production Hydrocarbon processing Mining Storm water Sump service
ComplementaryPump DesignsDepending uponapplication requirements,Flowserve can also
provide these designs: Vertical, double

Discharge Headwith ASMEClass 125 or 250 flat face flangeprovides a smooth transition of thepumped liquid into the dischargepiping. It also functions as amounting base for the driver
Prelubrication Connectionallowsconnection to an external lubricationsource for deep set pumps
Discharge Casewith hydraulicadapter ensures efficient transfer offlow to various column sizes
Impellers, Enclosed and Semi-opendesigned for maximum coverage ofall applications
Lock Colletprovides an interferencefit between the bowl shaft andimpeller to hold the impeller securely
in place. Keyed impellers are standardfor 500 m (20 in) and larger modelsand optional on other sizes
Suction Bellis designed to provideefficient flow of the liquid into theeye of the first stage impeller. Asuction case is provided for wellpump applications
Basket Strainerpreventsunwanteddebris from getting into the pump. Itis designed to exceed HydraulicsInstituteparameters. Cone strainersare provided for deepwellinstallations
Vertical Hollow Shaft Motorallows the pump headshaftto extend through the motorand provides impeller clear-anceadjustment with anadjustingnut located at the
top of the motor. A two-pieceheadshaft with a motor standis available when overheadclearance is inadequate toremove the motor
Vertical Solid Shaft Motorsupplied by customerrequest to provide superiorshaft support for mechanicalseal applications
High Pressure Stuffing Boxfor working pressures up to20 bar (300 psi). Other
stuffing box options arealso available
Open Lineshaft Constructionallows the lineshaft bearingsto be lubricatedby thepumped liquid
Column Pipeavailableflanged as shown or threadedto minimize well pump

Oil Lubrication
Enclosed Oil Lubricationisolatesthe lineshaft and bearings fromthe pumped liquid minimizingmaintenance in abrasive services.
Alternative lubricants such as cleanwater or grease can also be usedwith enclosed lineshaft construction
Heavy Duty Discharge HeadwithASME Class 150, 300, or 600 raisedface flange provides a rigid andstable support for high horsepowerdrivers. The mitred elbow reducesthe internal friction loss andreduces turbulence in thedischarge head. Cast irondischarge heads are available up to500 mm (20 in) discharge
Rigid Adjustable Couplingprovidesaccurate impeller clearance adjust-ment and overall shafting stability
Tension Bearingholds the enclosingtube and lineshaft bearings in align-ment. It also provides a chamberfor the lubricant as it enters theenclosing tube
Separate Steel Soleplateallowsgrouting and leveling of the pumpdischarge head without permanentlyanchoring the head. The pump canbe removed for service without
disturbing the grout
Flanged Column Pipecontains thepressure being generated by thepump and has a rabbet fit betweenthe flanges to maintain alignment
Keyed Impellerspositively lockedto the shaft eliminate shaft toimpeller movement. Stainless steelslotted keys prevent radial movementwhile the stainless steel split-ringkeys prevent axial movement. Colletmounted impellers are standard forimpellers up to 460 mm (18 in),with keyed impellers as an option
Enclosed Impellerprovides closerunning clearance between the bowlto maintain efficiency over a broadoperating range. Full range of semi-open impellers are available forparticular applications
Alignment Screwsallow positioningof the larger frame size motor onthe discharge head for final align-ment of the pump and motor shafts
Polished Steel Lineshaft, inAISI C-1045 for maximumstrength and reliablility,transmits the torquefromthe motorto the bowl shaftand impeller. Other shaft
materials are provided tosuit application
Enclosing Tube Stabilizeris integrally welded to the
column pipe to maintain therigidity and alignment of theenclosing tube. Rubberstabilizer for up to 355 mm(14 in) column size andsteel stabilizer for 400 mm(16 in) and larger
Enclosing Tubeprovideslineshaft protection from thepumped liquid. The lineshaftbearings are spaced at 1.5 m(5 ft) intervals to supportthe lineshaft
Keyed Lineshaft Couplingpositively locks the sectionsof shafting together. This isoptional for all pump sizes.Threaded coupling is avail-able up to 65 mm (2.5 in)lineshaft
Discharge Case withBypass Portallows positiveflow of the lubricant into theenclosing tube to lubricatethe lineshaft bearings
Bowl Bearing and SuctionBell Bearingwith highlength to diameter ratiosupport the bowl shaft aboveand below the impeller formaximum reliability
Bowl and Impeller WearRings, optionalfor enclosedimpellers only, provide amethod to renew clearancesand pump efficiency. Semi-open impellers maintainefficiency by impelleradjustment withoutdismantling the pump
