It reduces maintenancetime 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 0.004 in (0.10 mm) of clearance. For animpeller setting of 0.020 in(0.5 mm) count five notchescounterclockwise.

Move the bearing carrierclockwise the selected numberof notches. Tighten thesetscrews and check theimpeller clearance with thefeeler gage.

The Heart of the Pump: Shaft and Bearing Design

Flowserve offers the largestshaft and bearing componentsavailable in standard ANSIpumps. The following com-parison of a Durco Group IIpower end with that of a majorcompetitor demonstrates thebenefits of heavy-duty design.

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

Extended bearing lifecomparison is the ratio of theload ratings to the third power,or:

I.B.= 13,400 3

=1.59 (+59%)11,900

O.B.= 19,200 3

=1.61(+61%)16,400

Shafts (see Table 2)Solid shafts are recommendedover shaft sleeves because theyreduce the harmful effects ofdeflection and vibration. Whileshaft sleeves may simplifymaintenance, solid shaftsreduce it.

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

The formula I=L3/D4 offers anindex of deflection to comparepump designs where:I = index of deflectionL = length of shaft overhang

from bearingD = rigid shaft diameter

Note: The Deflection Index pro-vides an approximate comparisonof shaft stiffness. A detailedanalysis should be made todetermine actual shaft deflection.

FMSSame as FML but accommodatesseals with small gland bolt andgasket circles:• Single seals with all seat

mounting configurations can beinstalled

• This design is our secondaryrecommendation to the FML

FMICast-in integral gland is wellsuited for:• Single internal, flexibly

mounted seals• “Sanitary-type”

applications• Utilizes sleeve for seal

setting and fast installation

CBLOversize, cylindrical step boredesigned for seals with large glandbolt and gasket circles:• Dual internal component seals

isolate the seal chamber from theprocess with external sourceflush

• Single seal with throttle bushingand flush to boost pressure overflash point

CBSCylindrical bore designed forpacking arrangements andconventional seals with smallgland bolt and gasket circles

FMLPreferred selection in mostapplications. Designed for sealswith large gland bolt and gasketcircles:• Single internal cartridge seals• Dual internal/external cartridge

seals• Single internal component seals

with flexibly mounted seats• Dual internal “true” tandem

design cartridge seals


Advanced FM SealSentryDesign Technology• Self-Flushing• Self-Venting• Self-Draining

Seal life is extended due tosuperior purging of heat, solidsand vapors. Single seals canoften be selected where dualseals or external flush andthroat bushing combinationshad been used, such as onsolids, slurry and liquorservices. Flush plans 11, 32,52, 53, etc. can be eliminated.Costs are reduced. Pumpreliability is increased.

Flow Modifiers ExtendMechanical Seal MTBPM• Flow modifiers redirect flow

from circumferential to axial• Balanced flow with low

pressure drop in the chamberhelps keep solids in suspension,minimizing erosivecharacteristics of the process

• A mechanical seal creates acentrifuging action away fromits parts and into the returningflow path of the process liquid

• Solids and slurry merge in thereturning flow path and areflushed out of the seal chamber

The FM (flow modifiers)series features an enlarged,tapered bore with cast-inflow modifiers.


Jacketed Seal ChamberDesigned for effective heattransfer in the seal chamberarea or across the entire sur-face area of the process fluid.

Jacketed standard bore(CBS) whencooling the sealchamber is theobjective.

Jacketed FMchamber ispreferred whenprotection ofthe processtemperature isimportant.Maximizing seal life involves

proper selection of the sealchamber and seal and glandcombination. Generally, the sealfaces should be located directlyin the flush path.

Durco reverse vane impellersdeliver unequalled efficiencyand performance. This exclusiveimpeller design extends bearingand seal life.

• Low, predictable sealchamber pressure and thrustloads resulting from backvane pumping action andbalance holes

• Low required NPSH, lowestoverall of any standard pump

• Rear cover plate wearsurface as the flow path exitsthe rear of the impeller,placing abrasive wear on therear cover rather than themore expensive casing

Note: Recessed impellerpumps offer excellentsolids handling capabilities. See page 28.

• In-shop impeller adjustmentwith the only impeller designthat takes full advantage of theback pull out feature. Since thecritical running clearance is setbetween the rear of the impellerand the rear cover plate, bothimpeller and mechanical sealsettings can be done in theshop, “on the bench,” instead ofunder adverse field conditions

• Repeatable performanceassurance with the only impellerdesign that offers repeatabilityin seal chamber pressure andbearing thrust loads
