How to fix seal leakage in a tar pump
Thread Content
The leakage at the mechanical seal of the tar pump has been a problem since the unit was put into operation. I would appreciate it if experts could advise on how to resolve this issue. Pump type: centrifugal pump; Seal type: single-seal bellows; Operating medium: tar; Operating temperature: 210 degrees
1. Choose a high-quality mechanical seal. 2. Select appropriate flushing and cooling methods
The service life of mechanical seals at high temperatures is not very long; it might be advisable to use high-temperature magnetic pumps. We have used them in environments with even higher temperatures, and the results were good!
Choose a high-temperature magnetic pump or shielded pump
Horizontal centrifugal pumps with insulated jackets can be used; dynamic sealing can be employed for sealing, the temperature can reach 300–400°C, and there is no mechanical wear during operation
