Flowserve Pump 10-MFC-18

4.8 Final shaft alignment check

Rotate the shaft several times by hand to ensure there is no binding and all parts are free.

Recheck the coupling alignment to ensure no pipe strain exists.

6.1.2 Periodic inspection (semi-annual)

Check the coupling for correct alignment.

Inspect for worn driving elements.

4.5.4 Alignment criteria for MFC pumps

Verify maximum Total Indicator Reading (TIR) for Woods type coupling

Verify maximum Total Indicator Reading (TIR) for all metal flexible type coupling

5.8.3 Pumps fitted with mechanical seal

Ensure no adjustment is made to the mechanical seal

Is there any initial leakage from the seal?

Was the pump mechanical seal run in using clean liquid before pumping dirty liquids?

Was external flush or quench started before the pump was run?

Was external flush or quench allowed to flow after the pump stopped?

Ensure the mechanical seal was not run dry at any time

Is the leakage level of the mechanical seal acceptable?

Recommended Grease Fill Quantities

Select the frame for lubrication

Enter re-lubrication quantity for Line Bearing (g)

Enter re-lubrication quantity for Thrust Bearing (g)

Connect grease gun to the nipple

Press grease into the bearing housing until the first signs of it appear in the gap between the housing and shaft

Record the operating temperature of the bearing

Is the temperature rise above ambient within 55 °C (131 °F)?

Ensure the correct materials are used

Remove old packing and seal cage halves, then clean the stuffing box

Verify the packing is of correct type and size

Measure the stuffing box to determine the proper length of packing

Cut packing slightly shorter than measured length

Insert each ring of packing separately and seat it firmly

Stagger the rings so that successive joints are 90° to 180° angles apart

Remove rotor and reset seal if necessary for pumps with mechanical seals.

Is the desired ring gap achievable with current shim pack?

Restore or replace wearing surfaces if necessary.

Loosen the 4 screws (or nuts) between the bearing frame and the stuffing box head.

Break the shim joint by tightening the two adjusting bolts and remove the shims.

Adjust shim pack thickness to achieve desired wearing gap.

Select shim stock colour code for adjustment.
