Flowserve Pump 8-MFV-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

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

Measure Total Indicator Reading (TIR) for Woods type coupling - Parallel Misalignment

Measure Total Indicator Reading (TIR) for Woods type coupling - Total Angular Misalignment

5.1 Pre-commissioning procedure

Ensure the following pre-commissioning checks are completed

Fill pump bearings with recommended lubricant

Check all vent connections for complete filling of the pump

Verify the direction of rotation of the pump (Coupling spacer dismantled)

Ensure pump rotor and shaft seal are in correct axial position

Check readiness of all auxiliary systems (seal system, lubrication system) for startup

Verify all pipe work is connected correctly and absolutely tight

Ensure suction valve is open and discharge valve is closed or partially open as required

6.1.2 Periodic inspection (semi-annual)

Clean and oil the gland studs and nuts

Replace the packing if necessary

Enter the pump running hours from records

Should the bearings be inspected and re-lubricated?

Check foundation bolts for security of attachment and corrosion

Does the bearing lubricant require changing?

Check the coupling for correct alignment and worn driving elements

Ensure correct packing materials are used

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

Is the packing of the 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.
