The Heart of the Pump: Shaft and Bearing DesignFlowserve offers the largest shaft and bearing com po nents availableinstandardANSIpumps. The follow ing comparisonofaMark3 Group2powerendwith that of a major competitor demonstrates the benefits of heavy-duty design.

Mark 3Heavy-Duty

Shaft and Bearings

Unique External Micrometer Impeller Adjustment reduces maintenance time and, most impor tantly, is precisely accurate.

Simply loosen the setscrews. Using a wrench rotate the bear ing carrier counter clock-wise until the impeller lightly touches the rear cover plate.

Select the impeller setting. Each notch on the carrier ring represents exactly 0.10 mm (0.004 in) of clearance. For an impeller setting of 0.5 mm(0.020 in) count five notches counterclockwise.

Movethebearingcarrier clock wise the selected number of notches. Tighten the setscrews and check the impeller clearance with the feeler gauge.

Bearings (see Table 1)Greaterloadhandlingratingmeans extended bearing life.

Extended bearing life comparison is the ratio of the load ratings to the 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 recom mend ed over shaft sleeves because they reduce the harmful effects of deflectionandvibration.Whileshaft sleeves may simplify main-tenance, solid shafts reduce it.

Proper selection of wet-end materials of con struc tion and mechan ical seal design offset posi tive features of the shaft sleeve option.

Pump Division

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

Exclusive Reverse Vane Impeller with balance holes offers important performance enhancing, mainte nance-reducing advantages.

Front Vane Open Style Impeller is fully inter-changeable with the reverse vane impeller. Excellent choice for fibrous, stringy materials and certain applications requiring high shear against the casing.

In-shop Impeller Adjustment is practical as well as productive.

Flowserve Durco reverse vane impellers deliver unequalled efficiency and perfor mance. This exclu sive impeller design ex tends bearing and seal life.•Low, Predictable Seal

Chamber Pressure and Thrust Loads resulting from back vane pump ing action and balance holes

•Lowest Required NPSH of any standard pump

•Rear Cover Plate Wear Surface as the flow path exits the rear of the impeller. Abra sive wear is on the rear cover rather than the more expensive casing

Recessed Impeller pumps offer excellent solids-handling capa bilities. See page 28.

• In-shop Impeller Adjust ment with the only impeller design that takes full advan tage of the back pull-out feature. Since the criti cal running clear ance is set between the rear of the impel ler and the rear cover plate, both impeller and mechan ical seal set tings canbedoneintheshop,“onthebench,”insteadofunderadverse field conditions

•Repeatable Perfor mance Assurance with the only impeller design that offers repeatable seal chamber

pres sures and bearing thrust loads

Low Predictable Seal Chamber pressure means longer seal life

Rear Cover wear surfaceversus casing means lower replacement parts costs

Clearance is set to the rear cover in the shop – not to the casing which is left in the piping

Since an impeller can only be set in one direction, the reverse vane impeller has inherent advantages.

•Theimpellerpumpoutvanes clearance to the rear cover establishes:– seal chamber

– thrust loads and bearing life

An impeller cannot be adjusted to two locations.

Seal and bearing life are reduced due to increased loads after wear and maintenance adjustment.

Shaft Material Choices investment cast or high alloy bar stock available in a wide range of materi als.

Flowserve recommends the use of solid shafts rather than shaft sleeves to reduce the harmful effects of deflec tion and vibra tion. Shaft sleeves may simplify main te nance but solid shafts reduce it.

Shaft Choices

Friction-Welded: a steel power end fric tion-welded to a solid alloy wet end

Composite: a steel shaft end-to-end with an inte gral (i.e., not replaceable) sleeve of DC8, SD77 high silicon iron, ceramic (alumina or zirconia)

➄ Accurate machining under bear-ings ensures perfect bearing fits without vibration or hot running.

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

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

Extend Pump and Seal Life at Reduced Cost Flowserve offers five pre-engineered baseplate designs to improve pump performance and reduce costs (see page 17). Flowserve pre-engineered baseplates extend pump and seal life by reducing internal pump stress and vibrations. That is why Flowserve recommends reinforced rigid baseplates.

Plus, customers who know the value of pre-engineered and rein forced base plates help avoid potential con fusion in specifi ca tion inter pre tation, delays in ship ments and added costs.

Flowserve offers a broad range of metal and non-metallic, grout and stilt mounted designs and standard options. This provides broad flexi bility in choos ing the baseplate that best meets appli ca tion needs and operating budget.

Baseplates are Fundamental to Extending Pump LifeThe test stand provided three corner support of the ungrouted base plates. The addition of weights on the unsupported fourth corner caused baseplate distor tion. This distortion resulted in measurable shaft move ment that can cause problems with field instal-lations and nega tively affect pump reliability and life.

The twist test is a means of comparing rigid base plate designs. Correct ly installed rigid baseplates should not experience these twist effects. For more infor ma tion about the results of base plate test ing contact your local Flowserve sales representative.

ClearGuard and DurcoShield Non-metallic Safety GuardsClearGuardandDurcoShieldpump guards permit visual inspection of coupling and seal areas, respectively, while protecting personnel from potential safety hazards of rotating parts. Constructed of tough, durable, and transparent polycarbonatewithUVlightinhibitors, they are designed to withstand tough chemical processing environments.

ClearGuard Non-metallic Coupling Guard meets machinery guard safety guideline.Nothinglargerthan 6 mm (0.24 in) in diameter can enter the shell. Furthermore, the ability to inspect the couplingthroughClearGuardcan provide early warning of deteriorating or malfunctioning components.

DurcoShield* Splash and Shaft Guard is a one-piece shield that envelops the open areas between the bearing housing and casing. Suitable for applications to 150°C(300°F),DurcoShield protects users from:•Processfluidspray•Rotatingshaftandseal

Dynamic SealingWiththeFlowserveMark3Sealmatic pump, no mechanical seal is needed during operation. A dynamically sealing repeller (expeller) expels fluid from the seal chamber, making it ideal for hard to seal applications. Furthermore, the need for external flushing and process contamina-tion control are eliminated.

The Sealmatic pump conforms toANSIB73.1.

The Priming CycleTheMark3UnitizedSelf-Priming pump uses liquid recirculation to prime the pump. The pressure differential between the aerated liquid at the impeller and the non- aerated liquid in the priming chamber creates a vacuum that pulls liquid up the pipe. As a result,theMark3Unitized Self-Priming pump is ideal for suction lift applications or pumping liquids with entrained air or gases.
