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.
Installation 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.
Installation 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.
Installation 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. a) Put one machinist's level lengthwise on one of the two pads. b) Put the other machinist's level across the ends of the two pads. c) Level the pads by adjusting the four jackscrews in the corners. Make sure that the machinist's level readings are as close to zero as possible, both lengthwise and across.
Installation 7. 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 0.002 in./ft (0.0167 mm/m). The maximum variation from one side of the baseplate to the other is 0.015 in. (0.38 mm).

Maintenance • Tighten the screw only enough to turn the impeller without it slipping. • The allowed front shroud TIR is 0.060 in. (0.152 cm) • For the XS impeller, trim both the front and back shrouds and the vanes to a minimum diameter of 3.75 in. (9.53 cm). • When you trim between 3.00 in. (7.62 cm) and 3.75 in. (9.53 cm), trim only the front shroud and the vanes. Trimming examples 1. 2. 3. 4. Impeller Steel washer with rubber bond Paper gasket Arbor Figure 73: XS group 1. 2. 3. 4. 5.

Troubleshooting Troubleshooting Operation troubleshooting Symptom The pump is not delivering liquid. Cause The pump is not primed. The suction line is clogged. The impeller is clogged. The magnet is de-coupling. The suction line is clogged. The impeller is clogged. The magnet is de-coupling. The pump is not producing rated flow or head. Pump starts and then stops pumping. The bearings run hot. Pump is noisy or vibrates.
Troubleshooting Symptom The motor requires excessive power. The condition monitoring device shuts down the pump. Cause The head is lower than the rating and the pump has too much liquid. The liquid is heavier than expected. The head is higher than the rating, which is at capacity. The rotating parts are binding or are severely worn. The motor rotation is incorrect. The sleeve and thrust bearings are damaged. There is a plugged recirculation circuit. There is recirculation liquid vaporization.
Troubleshooting 1. Check to see if the plastic that surrounds the outboard thrust bearing is melted. 2. Check to see if the plastic that surrounds the carbon or silicon carbide impeller radial bearings is melted. 3. Check to see if the plastic that surrounds the inboard thrust bearings is melted. 4. If the impeller seizes on the shaft due to excessive heat, the shaft can spin in the shaft spider, which wears the inside diameter of the shaft spider.
