Flowserve Vertical Immersion Sump Pump 2E6x4SP-10H

Ensure the pump is stored in a clean, dry location away from vibration

Is the pump stored for less than 6 months?

Consult Flowserve for preservative actions if storage exceeds 6 months

Short term storage and packaging

Verify packaging and protection measures

Is the pump stored in a covered, dry location?

5.8.7 Normal vibration levels, alarm and trip

Measure the vibration velocity (unfiltered)

Is the vibration velocity within normal range (5.6 mm/s r.m.s. / 8.0 mm/s peak)?

Is the vibration velocity at alarm level (7.0 mm/s r.m.s. / 9.9 mm/s peak)?

Is the vibration velocity at shutdown level (11.3 mm/s r.m.s. / 16.0 mm/s peak)?

Record any changes in vibration velocity outside the preferred flow region

Observe pump for any abnormal noise or vibration

Check for any change in pump noise or vibration

Check the rotation of the motor before installing the coupling drive element

Verify the direction arrow on the support head [3160]

Turn off the driver power and lock it out to prevent starting during coupling assembly

Mount coupling hubs/sheaves on pump and motor shafts before attaching motor to the support head

Remove the sleeve if it has been installed before checking rotation

Remove all protective material from the coupling and shaft before installing the coupling

Check for any leaks from gaskets and seals

Verify the correct functioning of the shaft seal

Inspect impeller [2200] for excessive wear and etching due to corrosion.

Ensure the O-ring [4590.2] sealing surface and impeller threads are clean.

Check pump shaft [2100] for straightness.

Inspect the surface of the shaft in the bearing [3020.1-.2] areas for smoothness.

Ensure shaft surface is free of grooves, scratches, corrosion or wear.

Check ends of shaft for burrs and ensure shaft threads are clean.

Inspect the casing [1100] thoroughly, removing all burrs and foreign matter.

Check hydraulic passages for cleanliness.
