Goulds Pumps Pump 3355 2.5 x 4-8B-1500

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.

6.1 Maintenance schedule — Annual inspections

Does the pump performance satisfy process requirements?

If performance is unsatisfactory, disassemble the pump and inspect

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

If yes, describe how you will shorten the inspection intervals

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.

Are the hold-down bolts for the driver tight when taking indicator measurements?

Are the hold-down bolts for the driver loose before making alignment corrections?

6.1 Maintenance schedule — Three-month inspections

Check that the foundation and the hold-down bolts are tight

Is the pumped fluid abrasive or corrosive?

Is the environment classified as potentially explosive?

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 Total Indicated Reading (T.I.R.)
