Product Description

Product Description

General description

Model 3298
Model 3298 is a sealless, close-coupled or frame-mounted, centrifugal pump with an enclosed impeller that is driven by a synchronous magnetic coupling. All sizes of the 3298 meet the dimensional standards of ANSI B73.1 except for 1x1.5-5 and the 1.5x2-6.
Model SP3298
SP3298 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 the frame or adapter feet locations meet ANSI B73.1 dimensional standards.
Model V 3298
V3298 is a vertical in-line, sealless, close-coupled centrifugal pump with an enclosed impeller that is driven by a synchronous magnetic coupling. Model V3298 meets the dimensional standards of ANSI B73.2.
Casing
The casings are one-piece cast ductile iron lined with 1/8-inch Tefzel®1 and have ANSI class 150 flanges with a Tefzel® raised face. The 3298 and SP3298 are end-suction, top centerline discharge, and are self-venting. The V3298 is side-suction, side-discharge, and is also self­venting.
Impeller magnet assembly
The 3298 family uses 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 at the other end by the Tefzel® bearing spider.
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.
Rear impeller wear ring
A rear impeller wear ring is standard on M and L group pumps. A wear ring is not required on theS group. The wear ring is pressed into the rear of the impeller assembly. The wear ring reduces axial thrust in the M and L group pumps.
Magnetic coupling
The magnetic coupling is a coaxial synchronous type using rare earth magnets of neodymium iron (NdFe). This concept results in a compact design and allows the impeller to turn at the same speed as the motor, which means that there is no slip between the drive and the driven magnets.
Containment shell
The containment shell isolates the pumped liquid from the atmosphere. The containment shell construction is backed with vinylester FRP.
14 3298 Family Installation, Operation, and Maintenance Manual
Bearings
The standard material for radial bearings and thrust bearings is carbon. Pure Sintered Alpha Grade Silicon Carbide or DryGuard™ Pure Sintered Alpha Grade Silicon Carbide are optional.
Standard close-coupled mounting
The drive magnet assembly is keyed, setscrewed, and mounted directly to the motor shaft. This arrangement eliminates the need to perform pump-to-motor alignment.
Optional frame-mounted power end
The standard configuration for the optional power end is cast iron with flood-oil-lubricated ball bearings. Pure oil mist systems are available as an option. For the 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. The frame-mounted power end is not available on the V3298.

Baseplate-mounting procedures

Prepare the baseplate for mounting

1. Remove all the attached equipment from the baseplate.
2. Clean the underside of the baseplate completely.
3. If applicable, coat the underside of the baseplate with an epoxy primer. Use an epoxy primer only if you used an epoxy-based grout.
4. Remove the rust-proofing coat from the machined mounting pads using an appropriate solvent.
5. Remove water and debris from the foundation-bolt holes.

Install the baseplate using shims or wedges

Required tools:
• Two sets of shims or wedges for each foundation bolt
• Two machinist's levels
• Baseplate-leveling worksheet
This procedure is applicable to cast iron and fabricated steel baseplates.
1. Remove water and debris from the anchor bolt holes and sleeves.
2. If you use sleeve-type bolts, fill the bolt sleeves with packing material or rags to prevent grout from entering the bolt holes.
3. Put the sets of wedges or shims on each side of each foundation bolt. Make sure that the wedges extend 0.75 in. (19 mm) to 1.5 in. (38 mm) above the foundation to provide adequate space for grouting. The wedges will provide adequate support for the baseplate after it is grouted.

5. Put the machinist's levels across the mounting pads of the driver and the mounting pads of the pump.
20 3298 Family Installation, Operation, and Maintenance Manual
NOTICE:
Remove all dirt from the mounting pads in order to make sure that you achieve the correct leveling. Failure to do so can result in equipment damage or decreased performance.
6. Level the baseplate both lengthwise and across by adding or removing shims or moving the wedges. These are the leveling tolerances:
• A maximum difference of 0.125 in. (3.2 mm) lengthwise
• A maximum difference of 0.059 in. (1.5 mm) across
You can use the baseplate-leveling worksheet when you take the readings.
7. Hand-tighten the nuts for the foundation.

Install the baseplate using jackscrews

Tools required:
• Anti-seize compound
• Jackscrews
• Bar stock
• Two machinist's levels
• Baseplate-leveling worksheet
This procedure applies to the feature-fabricated steel baseplate and the advantage base baseplate.
1. Apply an anti-seize compound on the jackscrews. The compound makes it easier to remove the screws after you grout.
2. Lower the baseplate carefully onto the foundation bolts and perform these steps: a) Cut the plates from the bar stock and chamfer the edges of the plates in order to reduce
stress concentrations. b) Put the plates between the jackscrews and the foundation surface. c) Use the four jackscrews in the corners in order to raise the baseplate above the
foundation.
Make sure that the distance between the baseplate and the foundation surface is
between 0.75 in. (19 mm) and 1.50 in. (38 mm). d) Make sure that the center jackscrews do not touch the foundation surface yet.

Pump-to-driver alignment

Precautions
WARNING:
• Follow shaft alignment procedures in order to prevent catastrophic failure of drive components or unintended contact of rotating parts. Follow the coupling installation and operation procedures from the coupling manufacturer.
• Always disconnect and lock out power to the driver before you perform any installation or maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical injury.
• Electrical connections must be made by certified electricians in compliance with all international,
national, state, and local rules.
• Refer to driver/coupling/gear manufacturers installation and operation manuals (IOM) for specific
instructions and recommendations.
NOTICE:
Proper alignment is the responsibility of the installer and the user of the unit. Check the alignment of frame-mounted units before you operate the unit. Failure to do so can result in equipment damage or decreased performance.
Alignment methods
Three common alignment methods are used:
• Dial indicator
• Reverse dial indicator
• Laser
Follow the instructions from the equipment manufacturer when you use the reverse dial indicator or laser methods. Detailed instructions for using the dial indicator method are contained in this chapter.

Alignment checks

When to perform alignment checks
You must perform alignment checks under these circumstances:
• The process temperature changes.
• The piping changes.
• The pump has been serviced.
Types of alignment checks
Type of check When it is used
Initial alignment (cold alignment) Prior to operation when the pump and the driver are at ambient check temperature.
Final alignment (hot alignment) After operation when the pump and the driver are at operating check temperature.
Initial alignment (cold alignment) checks
When Why
Before you grout the baseplate This ensures that alignment can be accomplished. After you grout the baseplate This ensures that no changes have occurred during the grouting
After you connect the piping This ensures that pipe strains have not altered the alignment.

are at operating temperature.

Permitted indicator values for alignment checks

NOTICE:
The specified permitted reading values are valid only at operating temperature. For cold settings, other values are permitted. You must use the correct tolerances. Failure to do so can result in misalignment and reduced pump reliability.
When dial indicators are used to check the final alignment, the pump and drive unit are correctly aligned when these conditions are true:
• The total indicator runout is a maximum of 0.002 in. (0.05 mm) at operating temperature.
• The tolerance of the indicator is 0.0005 in./in. (0.0127 mm/mm) of indicator separation at operating temperature.

Attach the dial indicators for alignment

You must have two dial indicators in order to complete this procedure.
1. Attach two dial indicators on the pump coupling half (X): a) Attach one indicator (P) so that the indicator rod comes into contact with the perimeter
of the driver coupling half (Y). This indicator is used to measure parallel misalignment.
b) Attach the other indicator (A) so that the indicator rod comes into contact with the inner
end of the driver coupling half. This indicator is used to measure angular misalignment.
26 3298 Family Installation, Operation, and Maintenance Manual
2. Rotate the pump coupling half (X) in order to check that the indicators are in contact with the driver coupling half (Y) but do not bottom out.
3. Adjust the indicators if necessary.

Pump-to-driver alignment instructions

Perform angular alignment for a vertical correction
1. Set the angular alignment indicator to zero at the top-center position (12 o’clock) of the driver coupling half (Y).
