Flowserve Pump 8-MFC-24

Measure the current impeller clearance

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

Check for excessive wearing ring clearance

Renew or overhaul the rings if necessary

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

5.2.4.2 Recommended grease fill quantities

Verify grease fill quantities for Frame 8H

Connect grease gun to the nipple

Press grease into the bearing housing until it appears 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)?

Is the combined maximum temperature within 95 °C (204 °F)?

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

6.7.3 Bearing installation and removal

Ensure proper fit is maintained during bearing installation

Use pulling device to remove bearings from the shaft

Support bearing cone with a split ring and press out the shaft using an arbor press

Pull bearing cups out of the housing

Select method for mounting a bearing on the pump shaft

Heat the bearing to a uniform temperature

Quickly mount heated bearing on the shaft

Apply force using an arbor press if alternate method is used

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 anti-friction bearings properly fitted to the pump shaft?

Is there any distortion in the shaft keyways?

Is the impeller loose on the shaft?

Is the shaft bent or distorted?

Is the wear on the shaft slight enough for repair by metal spraying or plating?

Measure the shaft runout after repair (maximum 0.051 mm T.I.R.)
