| Cause |
| 1. Leaking packing or mechanical seal. Note some leakage is necessary to keep the packing cool.
(Over tightening will harden, become hot & score the pump shaft.) 2. Leakage could be from the body, body gaskets or drain plugs. (Sometime s a result of erosion or corrosion damage.) |
| Effect |
| Loss of service liquid. Potential gas leakage when shut down. In minor cases this may be a house keeping problem. In major cases this may lead to poor pump performance or damage to the pump. |
| Corrective Action |
| 1. Check packing and tighten or check & replace mechanical seal. Service liquid or contaminates from the process can coat or abrade mechanical seal faces.
2. Check the source of the leak. Repair may be necessary. |
