Possible Faults And Removal
| Faults | Reason | Removal |
| Pump fails to discharge any liquid | Air leaking into suction or gland Incorrect direction of pump rotation & impeller worn Suction pipe blocked |
Sealed leakage Check direction of rotation and replacing impeller Removal blockage |
| Shaft power consumption is excessive | Gland excessively tightened against packing rings Rotating component rubbing on a stationary part CZPT worn Drive belt tension too tight Flow rate too large Pump speed and ratio too high Misalignment or unparallel of drive shaft and pump shaft |
Loosen gland bolts Removal the rubbed part Replace the bearing Adjusting belt Modifying the pump duty and speed Adjusting drive and pump shaft |
| CZPT is over heating | Lubricants to much or less Containing impurity in the lubricant CZPT worn |
Lubricant as requirement Replace new lubricant Replace new bearing |
| CZPT has short time | Misalignment or unparallel of drive and pump shaft Shaft bent Impeller unbalanced due to wear CZPT object entered into the bearing or insufficient lubrication Incorrect procedure followed in fitting bearing |
Adjusting drive and pump shaft Replacing shaft Removal rubbing and replacing new impeller Clean the bearing Replacing or refitting the bearing |
| Excessive leakage from stuffing box | Packing rings excessive worn Shaft sleeve worn Dirty sealing water |
Replace new packing rings Replace shaft sleeve. Change clean sealing water |
| Pump vibrates Or is noisy | CZPT worn Impeller unbalanced Air entered into suction pipe or blocked Flow rate no-uniform and pump not primed |
Replace by new bearing Replace by new impeller Discharge air and remove block Improve on the pump feeding. |
