3 Product Description 3 Product Description 3.1 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.
3.2 Nameplate information Bearings The standard material for radial bearings and thrust bearings is carbon. Pure Sintered Alpha Grade Sili- con 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 arrange- ment eliminates the need to perform pump-to-motor alignment.

4.1 Pre-installation 4.1.2 Foundation requirements Precautions WARNING: Risk of serious injury or death in Ex-classified environments. If the pump is a Model NM3171, NM3196, 3198, 3298, V3298, SP3298, 4150, 4550, or 3107, ignition due to static electric discharge is possible from plastic parts that are not properly grounded. If the pumped fluid is non-conductive, drain and flush the pump with a conductive fluid under conditions that will not allow for a spark to be released to the atmosphere.

4.5 Piping checklists CAUTION: Do not move the pump to the pipe. This could make final alignment impossible. CAUTION: Never draw piping into place at the flanged connections of the pump. This can impose danger- ous strains on the unit and cause misalignment between the pump and driver. Pipe strain ad- versely affects the operation of the pump, which results in physical injury and damage to the equipment.

Exceeding any of the pump operating limits (e.g. - pressure, temperature, power, etc.) could result in equipment failure, such as explosion, seizure, or breach of containment.
5.2 Remove the coupling guard Precautions CAUTION: When a cartridge mechanical seal is used, ensure that the set screws in the seal locking ring are tightened and that the centering clips have been removed prior to startup. This prevents seal or shaft sleeve damage by ensuring that the seal is properly installed and centered on the sleeve.

5.10 Shut down the pump • Risk of explosion and serious physical injury. Do not operate pump with blocked system piping or with suction or discharge valves closed. This can result in rapid heating and vaporization of pumpage. • Risk of equipment damage and serious physical injury. Heat build-up can cause rotating parts to score or seize.
Page 61
5.11 Make the final alignment of the pump and driver • Misalignment can cause decreased performance, equipment damage, and even cata- strophic failure of frame-mounted units leading to serious injury. Proper alignment is the responsibility of the installer and the user of the unit. Check the alignment of all drive components prior to operating the unit.
6 Maintenance 6 Maintenance 6.1 Maintenance schedule Maintenance inspections A maintenance schedule includes these types of inspections: • Routine maintenance • Routine inspections • Three-month inspections • Annual inspections Shorten the inspection intervals appropriately if the pumped fluid is abrasive or corrosive or if the envi- ronment is classified as potentially explosive.
For ATEX applications bearing replacement (all) is recommended after 17,500 hours of operation. These bearing lubrication sections list different temperatures of the pumped fluid. If the pump is ATEX-certified and the temperature of the pumped fluid exceeds the permitted temperature values, then consult your ITT representative. 6.3 Required tools WARNING: This pump contains extremely strong magnets.
6.4 Disassembly NOTICE: Use a bench with a non-magnetic work surface such as wood or brass when you work on the pump. 6.4.2 Prepare the pump for disassembly Lock out power to the driver. WARNING: Failure to disconnect and lock out driver power may result in serious physical injury or death. Always disconnect and lock out power to the driver before performing any installation or main- tenance tasks.
