6.1 Maintenance schedule — Routine inspections

Perform routine inspection tasks

Is the pumped fluid abrasive or corrosive, or is the environment potentially explosive?

Shorten the inspection intervals if necessary

Are temperature and vibration levels retrieved using i-ALERT® monitoring sensor and app?

Flush and clean the system thoroughly to remove dirt or debris in the pipe system.

Will the temperatures of the pumped fluid exceed 93°C | 200°F?

Warm up the pump prior to operation if fluid temperatures exceed 93°C | 200°F.

Circulate a small amount of fluid through the pump until the casing temperature is within 38°C | 100°F of the fluid temperature.

Flow fluid from pump inlet to discharge drain for warm-up.

Soak for 2 hours at process fluid temperature.

Bring variable-speed drivers to the rated speed as quickly as possible.

Ensure set screws in the seal locking ring are tightened and centering clips removed if a cartridge mechanical seal is used.

Perform alignment checks under these circumstances

Enter the Total Indicated Reading (T.I.R.) at operating temperature

Enter the tolerance of the indicator

4.3.3 Alignment measurement guidelines

Rotate the pump coupling half and the driver coupling half together so that the indicator rods have contact with the same points on the driver coupling half.

Move or shim only the driver to make adjustments.

Ensure the hold-down bolts for the driver are tight when taking indicator measurements.

Ensure the hold-down bolts for the driver are loose before making alignment corrections.

6.2.5 Lubricate the bearings after a shutdown period

Flush out the bearings and bearing frame with a light oil to remove contaminants

Flush the bearing housing with the proper lubricating oil to ensure oil quality after cleaning

Make the final alignment of the pump and driver

Run the unit under actual operating conditions to reach operating temperature

Shut down the pump and the driver

Check the alignment while the unit is still hot

Check the Total Indicated Reading (T.I.R.)
