Flowserve Pump 16-MFC-24

6.1.7 Maintenance of shaft and shaft sleeve

Examine the shaft condition at key points

Is there any rusting or pitting on the shaft?

Are the anti-friction bearings properly fitted?

Is there any distortion in the shaft keyways?

Is the impeller loose on the shaft?

Is the shaft bent or distorted?

Is the sleeve worn appreciably?

Measure the depth of grooves on the sleeve (in mm)

Bearing installation and removal

Ensure proper fit is maintained during bearing installation

Was a pulling device used to remove bearings from the shaft?

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

Methods for mounting a bearing on the pump shaft

Heat the bearing to a uniform temperature

Quickly mount the heated bearing on the shaft

Apply force using an arbor press if alternate method is used

Use a tubular sleeve, ring, or small blocks to apply force to the cone

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?

Start external flush or quench before running the pump

Allow external flush or quench to flow after the pump has stopped

Was the mechanical seal ever run dry?

Is the leakage level of the mechanical seal acceptable?

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?

If temperature issues are observed, describe the actions taken

6.1.1 Routine inspection (daily/weekly)

Check for abnormal fluid or lubricant leaks

Check that sealant systems are full and operating normally

Check that shaft seal leaks are within acceptable limits

Check the level of oil lubricant

Is the condition of oil lubricant acceptable?

Enter running hours since last grease recharge or change

Check auxiliary supplies (e.g. heating/cooling) are functioning correctly
