Probable Cause | Possible Solutions |
1. Ball bearing defect | The ball bearings may be worn or improperly installed. Take pump out of service and inspect. |
2. Excessive lubricant | Check lubrication levels. Allow the pump to operate for 15 to 20 minutes with the lubrication plugs removed. This will permit any excess grease to escape the housing, leaving the correct residual amount for proper operation. |
3. Packing gland too tight | Loosen packing gland. |
4. Misalignment between pump and driver | Check pump and driver alignment. |
5. Mechanical defect | The pump shaft may be bent. Rotating elements may be binding. Take the pump out of service and inspect. |
Any difficulties in operation which are not covered by these general instructions should be taken up with the Chas S. Lewis & Co., Inc.
