One of the methods to reduce the operating costs of pumps, mixers and compressors is the regeneration of mechanical seals. We offer comprehensive regeneration of seals, both produced by KRAJ and other manufacturers.
The process of regeneration of a complete component seal is as follows:
1. External inspection of the seal,
2. Seal disassembly,
3. Thorough cleaning of all its components,
4. Technical verification, assessment of the condition of sliding surfaces, springs and metal elements,
5. Replacement of elastomeric elements of secondary seals and others not suitable for regeneration,
6. Polishing of slip rings,
7. Assembly and balancing of the seal,
8. Testing of the regenerated seal – tightness and operation test in real operating conditions. During the test, the final protocol of the regenerated seal is drawn up.
