How to deal with gland leakage in a horizontal slurry pump?

How to deal with gland leakage in a horizontal slurry pump? During the use of a slurry pump, we may frequently encounter the problem of gland leakage. What causes this and how should it be addressed? Let Panshi Pump Industry provide you with detailed explanations.

1. Firstly, we need to observe the amount of leakage. If the leakage is significant, we need to determine whether the pump is newly installed or has been in use for some time. If it is a new pump with significant leakage, it may be due to loose packing. In this case, we need to tighten the packing. If the pump has been in operation for some time and experiences excessive leakage, it is likely that the gland has worn out significantly, and timely replacement of the gland is required. It is important to note that a small amount of dripping from the gland seal of a slurry pump is considered normal.
2. Another possible cause is inadequate water supply to the shaft seal. If the pump uses a gland packing seal, high-pressure sealing water is required. If the water pressure is too low or the water flow is insufficient, it will not form an effective water seal, resulting in seal failure and significant leakage.
