STANDARD OPERATING PROCEDURE – PUMP MOTOR PPM ACTIVITY

 OBJECTIVE:

To establish a procedure for Pump motor PPM activity.

 

POLICY:

Proactively identify, correct, and report defects and damages to reduce down time and rate of failure.

 

RESPONSIBILITY:

 

Shift Engineer

 

PROCEDURE:

 

·        Before activity all PPE’s should available.

·        Apply LOTO equipment to the supply source.

·        Make sure System is isolated from the main supply.

·        Make sure that the speed of the motor is reduced to zero RPM.

·        Verify the integrity of the pump’s foundation and check the hold-down bolts for tightness.

·        Required to grease the pump bearing after every 2000 hours of run or as required.

·        Grease the motor bearings according to the manufacturer’s instructions.

·        Check the shaft alignment. At any job motto should be safety first.

·        In case of any major problem, inform the Facility Manager immediately.

 

 Bearing And Lubricant Condition

·        Monitor and log bearing temperatures, lubricant level, and vibration. Lubricant should be clear with no signs of bubbling. If bubbling is occurring, this is a good indication to add more lubricant to decrease the temperature of the bearings. If there is an increase in vibration in the bearings, this may be a good indicator of impending bearing failure.

 

Overall Pump Vibration

·        Imminent pump failure can be detected by monitoring overall pump vibration. Excessive vibration can result from a change in pump alignment, bearing failures, cavitation, and obstructions in the suction and discharge lines.

 

Pump Discharge Pressure

·        The difference in pressure read by the suction and discharge gauges will provide the total developed head pressure of the pump. Confirm this reading is within the pump’s designed performance. You can find this on the manufactured website or your operation manuals.

REVISION GUIDE:

Any change in the systems will need a change in the SOP.
