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, E3198, CV3198, 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.
4.2 Baseplate-mounting procedures J-type bolts Item Description Baseplate Shims or wedges Foundation Bolt Figure 19: J-type bolts 4.2 Baseplate-mounting procedures 4.2.1 Prepare the baseplate for mounting Remove all the attached equipment from the baseplate. Clean the underside of the baseplate completely. If applicable, coat the underside of the baseplate with an epoxy primer.
4.2 Baseplate-mounting procedures Shims or wedges Figure 20: Top view Shims or wedges Figure 21: Side view Lower the baseplate carefully onto the foundation bolts. Put the machinist's levels across the mounting pads of the driver and the mounting pads of the pump.
Page 35
4.2 Baseplate-mounting procedures Cut the plates from the bar stock and chamfer the edges of the plates in order to reduce stress concentrations. Put the plates between the jackscrews and the foundation surface. 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 19 mm | 0.75 in.

Level the pump mounting pads: NOTICE: Remove all dirt from the mounting pads in order to ensure that the correct leveling is achieved.
4.2 Baseplate-mounting procedures Check that the driver's mounting pads are level and adjust the jackscrews and the foundation bolts if necessary. The correct level measurement is a maximum of 0.167 mm/m | 0.002 in./ft . 4.2.4 Install the baseplate using spring mounting NOTICE: The spring-mounted baseplate is designed only to support piping loads from thermal expan- sion.

4.2 Baseplate-mounting procedures Lower the baseplate so that the stilts fit into the foundation cups. Level the baseplate and make the final height adjustments: Loosen the upper jam nuts and adjusting nuts. Adjust the height and level the baseplate by moving the lower adjusting nuts. When the baseplate is level, tighten the top adjusting nuts.
4.3 Install the pump, driver, and coupling 4.3 Install the pump, driver, and coupling Mount and fasten the pump on the baseplate. Use applicable bolts. Mount the driver on the baseplate. Use applicable bolts and hand tighten. Install the coupling. See the installation instructions from the coupling manufacturer.

4.4 Pump-to-driver alignment Guideline Explanation Check the alignment again after any mechanical adjustments. This corrects any misalignments that an adjust- ment may have caused. 4.4.4 Attach the dial indicators for alignment You must have two dial indicators in order to complete this procedure. Attach two dial indicators on the pump coupling half (X): Attach one indicator (P) so that the indicator rod comes into contact with the perimeter of the driver coupling half (Y).

If discharge pressure is not quickly attained, stop the driver immediately, reprime, and attempt to restart the pump. • To avoid risk of equipment damage, observe the pump for vibration levels, bearing tem- perature, and excessive noise.
5.12 Pump operation precautions 5.12 Pump operation precautions General considerations WARNING: • Risk of serious personal injury or property damage. Dry running may cause rotating parts within the pump to seize to non-moving parts. Do not run dry. • Risk of explosion and serious physical injury. Do not operate pump with blocked system piping or with suction or discharge valves closed.
5.13 Shut down the pump the pump. Note that different liquids freeze at different temperatures. Some pump designs do not drain completely and may require flushing with a liquid that doesn't freeze. 5.13 Shut down the pump WARNING: Precautions must be taken to prevent physical injury. The pump may handle hazardous and/or toxic fluids.
5.16 Make the final alignment of the pump and driver 5.16 Make the final alignment of the pump and 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 maintenance tasks.
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.
These bearing lubrication sections list different temperatures of the pumped fluid. If the pump is Ex-certified and the temperature of the pumped fluid exceeds the permitted temperature values, then consult your ITT representative. For Ex applications bearing replacement (all) is recommended after 17,500 hours of opera- tion.
6.2 Bearing maintenance 6.2.1 Lubricating-oil requirements Oil requirements based on temperature For the majority of operating conditions, bearing temperatures run between 49°C | 120°F and 82°C | 180°F, and you can use an oil of ISO viscosity grade 68 at 38°C | 100°F. If temperatures exceed 82°C | 180°F, refer to the table for temperature requirements.
Page 81
6.2 Bearing maintenance Figure 52: Bearing lubrication Wipe dirt from the grease fittings. Remove the two grease-relief plugs from the bottom of the frame. Fill both of the grease cavities through the fittings with a recommended grease until the fresh grease comes out of the relief holes.
Cartridge seals installed by the user require disengagement of the hold- ing clips prior to operation, allowing the seal to slide into place. If the seal has been installed in the pump by ITT, these clips have already been disengaged. Other mechanical seal types For other types of mechanical seals, refer to the instructions provided by the seal manufacturer for instal- lation and setting.
6.4 Disassembly Before you start the pump Check the seal and all flush piping. Mechanical seal life The life of a mechanical seal depends on the cleanliness of the pumped fluid. Due to the diversity of op- erating conditions, it is not possible to give definite indications as to the life of a mechanical seal. 6.4 Disassembly 6.4.1 Disassembly precautions WARNING:...

6.6 Reassembly 333A Figure 102: Position labyrinth oil-seal drain slots 6.6.4 INPRO labyrinth oil seal description Description The INPRO VBXX-D Labyrinth Oil Seal consists of the rotor (1), the stator (2), and the VBX Ring (3). The rotor (1) fits over the shaft and is held in place by an elastomeric drive ring (4). The drive ring causes the rotor to turn with the shaft and provides a positive, static seal against the shaft.
6.6 Reassembly NOTICE: The edges of the keyway can be sharp. Cover the keyway with tape. Failure to do so may re- sult in damaging the o-ring and/or labyrinth seal. Lightly lube the shaft and the drive ring (4) with lubricant. Lubricant helps in the installation process.
