Flowserve Pump 18-MFC-24

Recommended Grease Fill Quantities

Verify re-lubrication interval and quantities for frames

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, then stop greasing

Record the operating temperature of the bearing housing

Is the temperature rise above ambient within 55 °C (131 °F) or a combined maximum of 95 °C (204 °F)?

Is there a continuously rising temperature or an abrupt temperature rise?

Stop the pump immediately if there is a continuously rising temperature or an abrupt temperature rise

Ensure gland nuts are finger-tight only

Check for leakage from the gland after stuffing box is pressurized

Ensure visible leakage and concentric alignment of the gland ring

Check for overheating of the packing

If overheating occurs, stop the pump and allow it to cool

Upon restart, check for leakage at the packed gland

6.1.7 Maintenance of shaft and shaft sleeve

Examine the shaft condition at the following locations

Is there any rusting or pitting on the shaft?

Are the shaft keyways distorted?

Is the shaft bent or distorted?

Is the impeller loose on the shaft?

Is the sleeve grooved more than 3.0 mm (0.12 in.) deep?

Measure the shaft runout after repair

Is the shaft runout within 0.051 mm (0.002 in.) T.I.R.?

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

Measure the current impeller clearance

Is the impeller clearance within the nominal design range of 0.25 to 0.50 mm?

Check for excessive wearing ring clearance

Determine if the rings need renewal or overhaul due to decreased pump performance

Record any observations or issues found during the check
