Shaft andBearings
Unique ExternalMicrometer ImpellerAdjustment reducesmaintenance time and,most importantly,
is precisely accurate.
Simply loosen the setscrews.Using a wrench rotate the
bearing 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

= 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 shaftsleeve option.

Baseplates are Fundamentalto Extending Pump Life
The 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 means
of 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 seal
areas, 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 to
150C (300F), 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.

Innovative Radial VaneImpeller has a unique twist toprovide superior performance inlow-flow, high-head conditions.
Circular Concentric Casing ismore hydraulically efficient atlower flow rates. An internalbypass drilled in the dischargewithout breaching the casingwall or creating a potentialleak path. This helps tobalance pressures. Improved Performance
and ReliabilityThe innovative radial vaneimpeller and circular, concentriccasing of the Flowserve DurcoLo-Flo pump improve pump
performance and reliability whencompared to standard pumps.Furthermore, maintenance isreduced. Reduced radial loads up to
90% at low-flow conditions Minimized thrust loads Reduced NPSH requirements Reduced shaft vibration Extended bearing life Extended mechanical seal life Broadened application range

The Priming CycleThe Mark 3 Unitized Self-Priming pump uses liquidrecirculation to prime the pump.The pressure differentialbetween the aerated liquid
at the impeller and the non-aerated liquid in the primingchamber creates a vacuum thatpulls liquid up the pipe. As aresult, the Mark 3 UnitizedSelf-Priming pump is idealfor suction lift applications orpumping liquids with entrainedair or gases.
