Flowserve Pump 14-MFV-24

Verify heating requirements for shaft sleeve removal

Was the sleeve successfully removed after heating to 230 °C (450 °F)?

Was the sleeve successfully removed after heating to 260 °C (500 °F) and dousing with cold water?

Was the sleeve cut off successfully?

Clean the shaft and shaft sleeve thoroughly

Remove oil or grease from mating surfaces with a non-toxic solvent

Did the solvent dry completely before applying adhesive?

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.)

Normal Vibration Levels, Alarm and Trip

Measure the vibration velocity of the motor (0.75–7.5 kW)

Measure the vibration velocity of the motor (7.5–75 kW)

Measure the vibration velocity of the motor (75–298 kW)

Measure the vibration velocity of the motor (298–750 kW)

Is the vibration velocity within the normal range?

Is the vibration velocity above the alarm level?

Is the vibration velocity above the trip level?

Pump and Motor Bearings Temperature

6.1.2 Periodic inspection (semi-annual)

Clean and oil the gland studs and nuts

Replace the packing if excessive leakage cannot be reduced by gland adjustment

Enter the pump running hours from records

Should the bearings be inspected and re-lubricated based on hourly usage?

Has it been more than one year since the last cleaning and lubrication change?

Does the bearing lubricant require changing based on hourly usage?

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 temperature issues are detected and investigate the cause
