The Heart of the Pump: Shaft and Bearing DesignFlowserve offers the largestshaft and bearing componentsavailable in standard ANSIpumps. The followingcomparison of a Mark 3Group 2 power end withthat of a major competitordemonstrates the benefitsof heavy-duty design.

Pump Division

Mark 3Heavy-Duty

Shaft andBearings

Unique ExternalMicrometer ImpellerAdjustment reducesmaintenance time and,most importantly,is precisely accurate.

Simply loosen the setscrews.Using a wrench rotate thebearing carrier counterclock-wise until the impeller lightlytouches the rear cover plate.

Select the impeller setting. Each notch on the carrier ringrepresents exactly 0.10 mm (0.004 in) of clearance. For animpeller setting of 0.5 mm(0.020 in) count five notchescounterclockwise.

Move the bearing carrierclockwise the selectednumber of notches. Tightenthe setscrews and check theimpeller clearance with thefeeler gauge.

Bearings (see Table 1)Greater load handling ratingmeans extended bearing life.

Extended bearing life comparisonis the ratio of the load ratings tothe third power or:

I.B. = 6078 3

= 1.43 (+43%)5398

O.B. = 8709 3

= 1.61(+61%)7439

Shafts (see Table 2)Solid shafts are recommendedover shaft sleeves because theyreduce the harmful effects ofdeflection and vibration. Whileshaft sleeves may simplify main-tenance, solid shafts reduce it.

Proper selection of wet-endmaterials of construction andmechanical seal design offsetpositive features of the shaft sleeve option.

Flow Modifiers (FM) ExtendMechanical Seal MTBPM• Flow modifiers redirect flow

from circumferential to axial • Balanced flow with low

pressure drop in the chamberhelps keep solids in suspen-sion, minimizing erosion

• The mechanical seal creates acentrifuging action away fromits parts

• Solids and slurry mergeinto the returning flow pathand are flushed out of theseal chamber

Available Jacketed SealChambers are designedfor effective heat transferin the seal chamberarea or across theentire surface areaof the process fluid.• Use the jacketed

Radial Vane Impelleris available for low-flow,high-head applications.See pages 22 and 23.

Exclusive Reverse VaneImpeller with balanceholes offers importantperformance enhancing,maintenance-reducingadvantages.

Front Vane Open StyleImpeller is fully inter-changeable with thereverse vane impeller.Excellent choice forfibrous, stringy materialsand certain applicationsrequiring high shearagainst the casing.

In-shop ImpellerAdjustment is practical as well as productive.

Low Predictable Seal Chamberpressure means longer seal life

Rear Cover wear surfaceversus casing means lowerreplacement parts costs

Clearance is set to the rear coverin the shop – not to the casingwhich is left in the piping

Lowest Overall required NPSH of anystandard pump

Flowserve Durco reverse vaneimpellers deliver unequalled efficiency and performance. This exclusive impeller designextends bearing and seal life.• Low, Predictable Seal

Chamber Pressure and ThrustLoads resulting from backvane pumping action andbalance holes

• Lowest Required NPSH of anystandard pump

• Rear Cover Plate WearSurface as the flow pathexits the rear of the impeller.Abrasive wear is on the rearcover rather than the moreexpensive casing

Recessed Impellerpumps offer excellentsolids-handling capabilities. See page 28.

• In-shop Impeller Adjustmentwith the only impeller designthat takes full advantage ofthe back pull-out feature.Since the critical runningclearance is set between therear of the impeller and therear cover plate, both impellerand mechanical seal settingscan be done in the shop, “onthe bench,” instead of underadverse field conditions

• Repeatable PerformanceAssurance with the onlyimpeller design that offersrepeatable seal chamber pressures and bearing thrust loads

• Non-repeatable cycle life

Reverse Vane Impellerhas only one set ofpumping vanes and onecritical tolerance location– between the impellerand rear cover – to establish:• Performance• Efficiencies• Seal chamber pressures• Thrust/axial loads

Since an impeller can onlybe set in one direction,the reverse vane impellerhas inherent advantages.

Only Flowserve Durcoreverse vane impellersoffer repeatable perform-ance after wear andimpeller adjustment.

Front Vane Open StyleImpeller has two setsof pumping vanes and twocritical tolerance locations:• The front vane of the

impeller clearance to thecasing establishes:– performance– efficiencies

• The impeller pump outvanes clearance to therear cover establishes:– seal chamber

pressures andseal life

– thrust loads and bearing life

An impeller cannot beadjusted to two locations.

Seal and bearing life arereduced due to increasedloads after wear and maintenance adjustment.

Mark 3 shafts and sleevesare designed to improvepump reliability.

➄ Accurate machining under bear-ings ensures perfect bearing fitswithout vibration or hot running.

➅ Run-out of <0.001 in (0.03 mm)at mechanical seal allows sealfaces to run true.

➆ Critical surfaces ground to a sur-face finish of 0.4 micron in (16 µ)ensure the secondary sealingability of mechanical seals.

➇ Steel power ends handle higherhorsepower loads than stainless.

➀ Radiused “sled-runner” keywaysimprove strength at this stresspoint.

➁ Offset keyways aid shaft balance.

➂ Alloy identification on everyshaft and sleeve ensures thatthe right parts go in every time.

➃ Large radii fillets add strength.

Flowserve offers a family of fivetypes of pre-engineered baseplatedesigns to extend pump life andreduce costs.

Pump Division

Reducing Internal Stressand Vibration Extendsthe Life of Pumpand Motor PackagesPump users specify rigidbaseplate designs to:• Provide torsional lateral

and longitudinal rigidity• Improve vibration

dampening• Protect against transit

damage• Resist twisting during

installation• Maintain shaft alignment• Reduce installation and

shaft alignment time• Reduce diaphragming

or separation from grout• Improve pump, motor

and seal reliability• Reduce total life cycle

pump, motor andseal costs

Rigid Design Begins WithThick Plate ConstructionMetal baseplate sizes:• 139 to 258 feature

13 mm (1/2 in) steelplate construction

• 264 to 280 feature16 mm (5/8 in) steelplate construction

• 368 to 398 feature19 mm (3/4 in) steelplate construction

Polybase baseplates areconstructed of 76 mm (3 in) to 102 mm (4 in)solid polymer concrete.Baseplate types B, C, Dand E are reinforced withadded structural supportfor improved rigidity.

Baseplates are Fundamentalto Extending Pump LifeThe test stand provided threecorner support of the ungroutedbaseplates. The addition ofweights on the unsupportedfourth corner caused baseplatedistortion. This distortionresulted in measurable shaftmovement that can causeproblems with field instal-lations and negatively affectpump reliability and life.

The twist test is a meansof comparing rigid baseplatedesigns. Correctly installedrigid baseplates should notexperience these twist effects.For more information aboutthe results of baseplate testingcontact your local Flowservesales representative.

ClearGuard and DurcoShieldNon-metallic Safety GuardsClearGuard and DurcoShieldpump guards permit visualinspection of coupling and sealareas, respectively, whileprotecting personnel frompotential safety hazards ofrotating parts. Constructed oftough, durable, and transparentpolycarbonate with UV lightinhibitors, they are designedto withstand tough chemicalprocessing environments.

ClearGuard Non-metallicCoupling Guard meetsmachinery guard safetyguideline. Nothing larger than6 mm (0.24 in) in diametercan enter the shell. Furthermore,the ability to inspect thecoupling through ClearGuardcan provide early warning ofdeteriorating or malfunctioningcomponents.

DurcoShield* Splash and ShaftGuard is a one-piece shield thatenvelops the open areas betweenthe bearing housing and casing.Suitable for applications to150°C (300°F), DurcoShieldprotects users from:• Process fluid spray• Rotating shaft and seal

components

Note: DurcoShield is not acontainment system or a sealbackup system. It is a limitedprotection device. It willreduce, but not eliminate,the probability of injury.
