PUMP DESCRIPTION

The Model 3298 is a sealless close coupled or frame mounted centrifugal pump with an enclosed impeller that is driven by a synchronous magnetic coupling and meets

dimensional standards of ANSI B73.1. (The 1x1

-5 is not

ANSI dimensional.)

The SP 3298 is a self-priming sealless close coupled or frame mounted centrifugal pump with an enclosed impeller that is driven by a synchronous magnetic coupling. The pump and frame / adapter feet locations meet ANSI B73.1 dimensional standards.

The V 3298 is a vertical in-line sealless close coupled centrifugal pump with an enclosed impeller that is driven by a synchronous magnetic coupling and meets the dimensional standards of ANSI B73.2.

Casing - The casings are one piece cast ductile iron lined with 1/8" TEFZEL a TEFZEL

®1

and have ANSI class 150 flanges with

raised face. The 3298 and SP 3298 are end suction, top centerline discharge and are self-venting. The V 3298 is side suction, side discharge and is also self-venting.

Impeller Magnet Assembly - The 3298 family utilizes a one or two piece impeller magnet assembly. The magnet ring is balanced to ISO 1940 G6.3 levels and is sealed within the solid enclosed TEFZEL

impeller magnet

assembly.

Stationary Shaft - The impeller magnet assembly rotates about a solid stationary silicon carbide shaft. The shaft is supported at one end by the containment shell and the other end by the TEFZEL

bearing spider.

Rear Impeller Wear Ring - is standard on M and L group size pumps and is not required on S group sizes. The wear ring is pressed into the rear of the impeller assembly. The wear ring reduces axial thrust in the M and L group size pumps.

Magnetic Coupling - is a coaxial synchronous type using rare earth magnets. This concept results in a compact design and allows the impeller to turn at the same speed as the motor, (i.e. there is no slip between the drive and driven magnets.)

Magnets - Neodymium Iron (NdFe).

Containment Shell - isolates the pumped liquid from the

atmosphere. The containment shell construction is backed with vinylester FRP.

Radial Bearings and Thrust Bearings - Goulds standard bearing material is carbon with optional Pure Sintered Alpha Grade Silicon Carbide or DryGuard™ Pure Sintered Alpha Grade Silicon Carbide.

Standard Close Coupled Mounting - The drive magnet assembly is keyed, set screwed and mounted directly to the motor shaft. This arrangement eliminates the need to perform pump/motor alignment.

Optional Power End

- The standard configuration is cast iron with flood oil lubricated ball bearings. Pure oil mist systems are available as an option. For protection and reliability of the bearings and the lubricant, a labyrinth seal is provided. On the inboard side a lip seal is used to prevent leakage of oil into the magnetic drive assembly.

Bearing Spider - The bearing spider constructed from solid TEFZEL

houses one of the key silicon carbide thrust bearings in the pump and supports the stationary shaft at one end.

Equipment that is to be installed in a potentially explosive environment must be done so in accordance with the

following installation instructions.

BASEPLATE INSPECTION

1. Remove all equipment.

2. Completely clean the underside of baseplate. It is

sometimes necessary to coat the underside of the baseplate with an epoxy. This may have been purchased as an option.

3. Remove the rust preventative solution from the machined pads with an appropriate solution.

SITE / FOUNDATION

A pump should be located near the supply of liquid and have adequate space for operation, maintenance, and inspection.

Baseplate mounted pumps are normally grouted to a concrete foundation, which has been poured on a solid footing. The foundation must be able to

absorb any vibration and to form a permanent, rigid support for the pumping unit.

The location and size of the foundation bolts are shown on the outline assembly drawing, provided with the pump data package.

3298 Family Rev. 4/07 15

All equipment being installed must be properly

grounded to prevent unexpected static electric discharge. This includes ensuring that the PFA lined pumps are pumping fluids that are conductive. If not, a static electric discharge may occur when the pump is drained and disassembled for maintenance purposes.

Foundation bolts commonly used are sleeve type (Fig. 10) and J type (Fig. 11). Both designs permit movement for final bolt adjustment.

1. Inspect foundation for dust, dirt, oil, chips, water, etc. and remove any contaminants. Do not use oil-based cleaners as grout will not bond to it.

2. Prepare the foundation in accordance with the grout manufacturer’s recommendations.

Fig. 10

Fig. 11

LEVEL BASEPLATE

CAST IRON / FABRICATED STEEL

1. Place two sets of wedges or shims on the foundation, one set on each side of every foundation bolt

(Fig. 12, 13). The wedges should extend .75 in. (20 mm) to 1.5 in. (40 mm) above the foundation, to allow for adequate grouting. This will provide even support for the baseplate once it is grouted.

2. Remove water and/or debris from anchor bolt holes/sleeves. If the sleeve type bolts are being used, fill the sleeves with rags to prevent grout from entering.

3. Carefully lower baseplate onto foundation bolts.

4. Level baseplate to within .125 in.(3mm) over the length of the base and .062 in. (1.5 mm) over the width of the base by adjusting shims or wedges.

5. Hand tighten bolts.

Fig. 13

Fig. 12

16 3298 Family Rev. 4/07

FEATURE FABRICATED STEEL/ API STYLE

(BASEPLATES PROVIDED WITH VERTICAL

LEVELING ADJUSTORS)

1. Coat the jack screws with an anti-seizing compound to allow for easy removal after the grout has been cured.

2. Cut round circular plates from bar stock to set the jack screws on. The edges of the plates should be chamfered to reduce stress concentrations.

3. Set the baseplate on the foundation and use the four corner jack screws to raise the baseplate off the foundation 0.75" to 1.5" (Fig. 14). The two center jack screws should not be touching the foundation.

Fig. 14

4. Place two machinist levels on the motor pads, one lengthwise on a single motor pad, and another across the ends of both motor pads (Fig 15).

NOTE: When using a machinist level, it is important that the surface being leveled is free of all contaminants, such as dust, to ensure an accurate reading.

7. Place the two levels on the pump pads, one lengthwise on a single pump pad, and another across the middle of both pump pads. (Fig. 16)

Fig. 16

8. Level the pump pads as close to zero as possible, in both directions, by adjusting the jack screws.

9. Install the anchor bolts until they are hand tight.

10. Return the levels to the motor pads and check the level measurements.

11. Adjust the jack screws and anchor bolts, if necessary, until all level measurements are within the design requirements of 0.002 in./ft.

12. When taking readings, center the level over the pad being measured.

NOTE: The Baseplate Leveling Worksheet provided may be used when taking readings.

5. Level the motor pads as close to zero as possible, in both directions, by adjusting the four jack screws.

6. Next, turn down the center jack screws so that they are resting on their metal discs on the foundation.

ALIGNMENT AND ALIGNMENT PROCEDURE

! WARNING

Before beginning any alignment procedure, make sure driver power is locked out. Failure to lock out driver power can result in serious personal injury.

Alignment procedures must be followed to prevent

unintended contact of rotating parts. Follow coupling manufacturer's coupling installation and operation procedures.

To remove guard, refer to coupling guard assembly/ disassembly instructions.

The points at which alignment is checked and adjusted are:

Initial Alignment is done prior to operation when

the pump and the driver are at ambient temperature.

Final Alignment is done after operation when the

pump and driver are at operating temperature.

Alignment is achieved by adding or removing shims from under the feet of the driver and shifting equipment horizontally as needed.

NOTE: Proper alignment is the responsibility of the installer of the unit.

Accurate alignment of the equipment must be attained. Trouble-free operation can be accomplished by following these procedures:

ALIGNMENT CHECKS

Initial Alignment (Cold Alignment)

Before Grouting Baseplate - To ensure alignment can be

obtained.

Final Alignment (Hot Alignment)

After First Run - To obtain correct alignment when both

pump and driver are at operating temperature. Thereafter, alignment should be checked periodically in accordance with plant operating and maintenance procedures.

NOTE: Alignment check must be made if process temperature changes, piping changes, and/or pump service is performed.

ALIGNMENT CRITERIA

Good alignment is achieved when the dial indicator readings as specified in the alignment procedure are .002 in. (.05 mm) Total Indicated Reading (T.I.R.) or less when the pump and driver are at operating temperature (Final Alignment).

During the installation phase, however, it is necessary to set the parallel alignment in the vertical direction to a different criteria due to differences in expansion rates of the pump and driver. Table 2 below shows recommended cold settings for electric motor driven pumps based on different pumpage temperatures. Driver manufacturers should be consulted for recommended cold settings for other types of drivers (steam turbines, engines, etc.).

Table 2

Cold Settings of Parallel

Vertical Alignment

Pumpage

Temperature Set Driver Shaft

50°F (10°C) .002in. (.05mm) LOW

150°F (65°C) .001in. (.03mm) HIGH

250°F (120°C) .005in. (.12mm) HIGH

After Grouting Baseplate - To ensure no changes to

alignment have occurred during grouting process.

After Connecting Piping - To ensure that pipe strains

haven’t altered alignment. If changes have occurred, alter piping to remove pipe strains on pump flanges.

3298 Family Rev. 4/07 19

SET UP

1. Mount two dial indicators on one of the coupling halves (X) so they contact the other coupling half (Y) (Fig. 17).

2. Check setting of indicators by rotating coupling half X to ensure indicators stay in contact with coupling half Y but do not bottom out. Adjust indicators accordingly.

Fig. 17

MEASUREMENT

1. To ensure accuracy of indicator readings, always rotate both coupling halves together so indicators contact the same point on coupling half Y. This will eliminate any measurement problems due to runout on coupling half Y.

2. Take indicator measurements with driver feet hold down bolts tightened. Loosen hold down bolts prior to making alignment corrections.

3. Take care not to damage indicators when moving driver during alignment corrections.

Fig. 18

4. Repeat steps 1 through 3 until indicator A reads .002 in (.05 mm) or less.

Horizontal Correction (Side to Side)

1. Zero indicator A on left side of coupling half Y, 90° from top dead center (9 o’clock).

2. Rotate indicators through top dead center to the right side, 180° from the start (3 o’clock). Observe needle and record reading.

3. Negative Reading - The coupling halves are further apart on the right side than the left. Correct by either sliding the shaft end of the driver to the left or the other end to the right.

Positive Reading - The coupling halves are closer together on the right side than the left. Correct by either sliding the shaft end of the driver to the right or the other end to the left (Fig. 19).

4. Repeat steps 1 through 3 until indicator A reads .002 in. (.05 mm) or less.

ANGULAR ALIGNMENT

A unit is in angular alignment when indicator A (Angular indicator) does not vary by more that .002 in. (.05 mm) as measured at four locations 90° apart.

Vertical Correction (Top to Bottom)

1. Zero indicator A at top dead center (12 o’clock) of coupling half Y.

2. Rotate indicators to bottom dead center (6 o’clock). Observe needle and record reading.

3. Negative Reading - The coupling halves are further apart at the bottom than at the top. Correct by either raising the driver feet at the shaft end (add shims) or lowering the driver feet at the other end (remove shims) (Fig. 18).

Positive Reading - The coupling halves are closer at the bottom than at the top. Correct by either lowering the driver feet at the shaft end (remove shims) or raising the driver feet at the other end (add shims).

5. Re-check both horizontal and vertical readings to ensure adjustment of one did not disturb the other. Correct as necessary.

20 3298 Family Rev. 4/07

Fig. 19

PARALLEL ALIGNMENT

A unit is in parallel alignment when indicator P (parallel indicator) does not vary by more than .002 in. (.05 mm) as measured at four points 90° apart at operating temperature. Note the preliminary cold setting criteria, Table 2.

Vertical Correction (Top to Bottom)

1. Zero indicator P at top dead center of coupling (12 o’clock) half Y (Fig. 19).

2. Rotate indicator to bottom dead center (6 o’clock). Observe needle and record reading.

3. Negative Reading - Coupling half X is lower than coupling half Y. Correct by removing shims of thickness equal to half of the indicator reading under each driver foot.

Positive Reading - Coupling half X is higher than coupling half Y. Correct by adding shims of thickness equal to half of the indicator reading from each driver foot (Fig. 20).

Positive Reading - Coupling half Y is to the right of coupling half X. Correct by sliding driver evenly in the appropriate direction.

Fig. 21

NOTE: Failure to slide motor evenly will affect horizontal angular correction.

4. Repeat steps 1 through 3 until indicator P reads .002 in. (.05 mm) or less.

5. Re-check both horizontal and vertical readings to ensure adjustment of one did not disturb the other. Correct as necessary.

Fig. 20

NOTE: Equal amounts of shims must be added to or removed from each driver foot. Otherwise the vertical angular alignment will be affected.

4. Repeat steps 1 through 3 until indicator P reads within .002 in. (.05 mm) or less when hot, or per Table 1 when cold.

Horizontal Correction (Side to Side)

1. Zero indicator P on the left side of coupling half Y, 90° from top dead center (9 o’clock).

2. Rotate indicators through top dead center to the right side, 180° from the start. Observe needle and record reading (3 o’clock).

3. Negative Reading - Coupling half Y is to the left of coupling half X. Correct by sliding driver evenly in the appropriate direction (Fig. 21).

COMPLETE ALIGNMENT

A unit is in complete alignment when both indicators A (angular) and P (parallel) do not vary by more than .002 in. (.05 mm) as measured at four points 90° apart.

Vertical Correction (Top to Bottom)

1. Zero indicators A and P at top dead center (12 o’clock) of coupling half Y.

2. Rotate indicator to bottom dead center (6 o’clock). Observe the needles and record the readings.

3. Make corrections as outlined previously.

Horizontal Correction (Side to Side)

1. Zero indicators A and P on the left side of coupling half Y, 90° from top dead center (9 o’clock).

7. Tighten foundation bolts.

ALIGNMENT CHECK

Re-check alignment before continuing, using methods previously described.

22 3298 Family Rev. 4/07

PIPING

Guidelines for piping are given in the Centrifugal Pump section of the “Hydraulic Institute Standards” and should be reviewed prior to pump installation.

! WARNING

Never draw piping into place by forcing at the flanged connections of the pump. This will impose dangerous strains on the unit and cause misalignment between pump and driver. Pipe strain can adversely effect the operation of the pump. That could result in serious personal injury and damage to equipment.

Flange loads from the piping system, including

those from thermal expansion of the piping, must not exceed the limits of the pump. Casing deformation can result in contact with rotating parts and result in excess heat generation, sparks and premature failure.

1. All piping must be supported independently and must line up naturally with the pump flanges.

2. Piping runs shall be designed to minimize friction losses.

3. DO NOT make final connection of piping to pump until grout has hardened and pump and driver hold-down bolts have been tightened.

4. It is suggested that expansion loops or joints, if used, be properly installed in suction and/or discharge lines when handling liquids at elevated temperatures, so linear expansion of piping will not draw pump out of alignment (Fig. 24 & 25).

Fig. 25

5. The piping should be arranged to allow pump flushing prior to removal of the unit on services handling corrosive liquids.

6. System should be thoroughly cleaned prior to installation.

SUCTION PIPING

! WARNING

NPSHAmust always exceed NPSHRas shown on Goulds performance curves received with order. Reference Hydraulic Institute for NPSH and pipe friction values needed to evaluate suction piping.

Properly installed suction piping is a necessity for trouble free pump operation. Suction piping should be flushed

BEFORE connection to the pump.

1. Use of elbows close to the pump suction flange should be avoided. There should be a minimum of 2 pipe diameters of straight pipe between the elbow and suction inlet. Where used, elbows should be long radius (Fig. 26)

Fig. 24

3298 Family Rev. 4/07 23

CORRECT

CORRECT PIPING

Fig. 26

Fig. 28

Suction Lift Conditions

1. Suction pipe must be free from air pockets

Fig. 27

2. Use suction pipe one or two sizes larger than the pump suction, with a reducer at the suction flange. Suction

piping should never be of smaller diameter than the pump suction.

3. Reducers should be eccentric at the pump suction flange with sloping side down and horizontal side at the top (Figs. 26, 27, 28).

Pump must never be throttled on suction side.

4. Suction strainers, when used, must have a net “free area” of at least three times the suction pipe area.

5. Separate suction lines are recommended when more than one pump is operating from the same source of supply.

CAUTION

2. Suction piping must slope upwards to pump.

3. All joints must be air tight.

4. A means of priming the pump must be provided, such as a foot valve, except for the self priming pump.

Suction Head/Flooded Suction Conditions

1. An isolation valve should be installed in the suction line at least two pipe diameters from the suction to permit closing of the line for pump inspection and maintenance.

2. Keep suction pipe free from air pockets.

3. Piping should be level or slope gradually downward from the source of supply

4. No portion of the piping should extend below pump suction flnge.

5. The size of entrance from supply should be one or two sizes larger than the suction pipe.

6. The suction pipe must be adequately submerged below the liquid surface to prevent vortices and air entrainment at the supply.

24 3298 Family Rev. 4/07

INCORRECT PIPING

DISCHARGE PIPING

1. Isolation and check valves should be installed in discharge line. Locate the check valve between isolation valve and pump, this will permit inspection of the check valve. The isolation valve is required for priming, regulation of flow, and for inspection and maintenance of pump. The check valve prevents pump or seal damage due to reverse flow through the pump when the driver is turned off.

2. Increasers, if used, should be placed between pump and check valves.

3. Cushioning devices should be used to protect the pump from surges and water hammer, if quick-closing valves are installed in system.

FINAL PIPING CHECK

After Connecting Piping to the Pump

CORRECT PIPING

Fig. 29

Rotate shaft by hand to ensure it rotates smoothly

and there is no rubbing which could lead to excess heat generation and or sparks.

1. Rotate shaft several times by hand to be sure that there is no binding and all parts are free.

2. Check alignment, per the alignment procedure outlined previously to determine absence of pipe strain. If pipe strain exists, correct piping.

A build up of gases within the pump, sealing system

and or process piping system may result in an explosive environment within the pump or process piping system. Ensure process piping system, pump and sealing system are properly vented prior to operation.

PREPARATION FOR START-UP

When installing in a potentially explosive environ-

ment, please ensure that the motor is properly certified.

CHECKING ROTATION FRAME MOUNTED

Serious damage may result if pump is run in the wrong rotation.

1. Lock out power to driver.

! WARNING

Lock out driver power to prevent accidental start-up that could result in serious personal injury.

2. Make sure coupling spacer is removed and coupling hubs are fastened tightly to the shafts and are not loose.

NOTE: Pump is shipped with coupling spacer removed.

3. Unlock driver power.

CAUTION

4. Make sure everyone is clear. Jog driver just long enough to determine direction of rotation. Rotation must correspond to arrow on bearing frame.

5. Lock out power to driver.

COUPLE PUMP AND DRIVER

! WARNING

Lock out driver power to prevent accidental start-up that could result in serious personal injury.

Lubricate coupling per manufacturer’s instructions and install coupling spacer.

INSTALL COUPLING GUARD

Install coupling guard as defined in the appendix.

! WARNING

Never operate a pump without a coupling guard properly installed. Operating pump without a properly installed coupling guard can result in serious personal injury.

3298 Family Rev. 4/07 27

CHECKING ROTATION - CLOSE COUPLED

! CAUTION

Serious damage may result if pump is run in the wrong rotation.

1. Unlock driver power.

2. Make sure everyone is clear. Jog driver just long enough to determine direction of rotation. Rotation of motor fan must correspond to arrow on close coupled frame.

LUBRICATING BEARINGS

Bearings must be lubricated properly in order to

prevent excess heat generation, sparks, and premature failure.

Flood Oil Lubrication - Pumps are shipped without oil. Fill bearing frame with oil through filler connection until oil level reaches center of sight-glass (Fig. 31). A high quality turbine type oil with rust and oxidation inhibitors should be used as specified in Table 6.

Close Coupled Pumps - Pump does not have ball bearings. Consult motor instruction book for required lubrication.

! WARNING

Operation of the unit without proper lubrication will cause bearing failure and pump seizure.

STARTING PUMP

1. Make sure suction valve and any recirculation or cooling lines are open.

2. Fully close or partially open discharge valve as dictated by system conditions.

3. Start driver.

Fig. 31

CONNECT CONDITION MONITORING DEVICES

If unit is equipped with power monitoring systems, this must be connected.

PRIMING PUMP

Never start pump until properly primed (pump casing and suction piping are full of liquid). Components such as internal sleeve bearings depend on liquid for lubrication and will quickly fail if run dry.

Your particular system conditions will dictate method used to prime pump.

! CAUTION

Continuous operation against closed discharge valve will cause pump to overheat. Overheating the magnetic drive assembly will weaken or ruin the magnets.

! CAUTION

Immediately observe pressure gauges. If discharge pressure is not quickly attained, stop driver, reprime and attempt to restart.

4. Slowly open discharge valve until the desired flow is obtained.

Continuous operation against closed discharge valve may vaporize liquid creating an explosive hazard due to confined vapor under high pressure and temperature.

! WARNING

28 3298 Family Rev. 4/07

OPERATION

GENERAL CONSIDERATIONS

Always vary capacity with valve in discharge line. NEVER throttle flow from suction side.

Driver may overload or magnets de-couple if pumpage specific gravity (density) is greater than originally assumed, or rated flow rate is exceeded.

Always operate the pump at or near the rated conditions to prevent damage resulting from cavitation or recirculation.

Do not operate above rated temperature range of magnets as this will weaken or ruin the magnets.

Service temperature in an ATEX classified environ-

ment is limited by Table 1 in the Safety section.

CAUTION

Table 4

Temperature Ratings

Group Size Rated Temperature

XS 1x1.5-5 250° F (121° C)

S All 250° F (121° C)

M All 250° F (121° C)

L All 250° F (121° C)

Driver may overload if the pumpage specific gravity (density) is greater than originally assumed, or the rated flow rate is exceeded.

Always operate the pump at or near the rated conditions to prevent damage resulting from cavitation or recirculation.

Damage occurs from:

1. Increased vibration levels - Affects bearings.

2. Increased radial loads - Stresses on shaft and bearings.

3. Heat build up - Vaporization causing rotating parts to score or seize.

4. Cavitation - Damage to internal surfaces of pump.

Goulds recommends the use of a power monitor to prevent pump damage from systems which have the potential for dry run operation. Refer to Appendix for information on power monitors.

CAUTION

DRAINING TANKS / DRY RUN OPERATION

OPERATING AT REDUCED CAPACITY

! WARNING

Do NOT operate pump below minimum rated flows or with discharge valve closed. These conditions may vaporize liquid creating an explosive hazard due to confined vapor under high pressure and temperature.

SUCTION VALVE CLOSED / DRY RUN OPERATION

! WARNING

Do not operate pump with suction valve closed. Operating pump after suction valve closed will cause wear of thrust and radial bearings and pump failure. Operating pump with suction valve closed may vaporize liquid creating an explosvie hazard due to confined vapor under high pressure and temperature.

Always vary capacity with regulating valve in the discharge line. NEVER throttle flow from the suction side.

CAUTION

! WARNING

After pump has drained tank, it should be shut down immediately. Operating pump after the tank has been drained of liquid will cause wear of thrust and radial bearings and pump failure. Operating pump after tank has been drained of liquid may vaporize liquid creating an explosive hazard due to confined vapor under high pressure and temperature.

Goulds recommends the use of a power monitor to prevent pump damage from systems which have the potential for dry run operation.

DISCHARGE VALVE CLOSED

! WARNING

Do not operate pump with discharge valve closed. Operating pump with a closed discharge valve may vaporize liquid creating an explosive hazard due to confined vapor under high pressure and temperature.

Goulds recommends the use of a power monitor and/or a minimum flow by-pass line to prevent pump damage from systems which have the potential for closed discharge operation.

3298 Family Rev. 4/07 29

OPERATING UNDER FREEZING CONDITIONS

Exposure to freezing conditions, while pump is idle, could cause liquid to freeze and damage the pump. Liquid inside pump should be drained. Liquid inside cooling coils, if supplied, should also be drained.
