Before repairs can begin, the mechanical seal needs to be inspected to determine the magnitude of the damage that it has suffered. In this way, a visual inspection must be done on the external and internal parts of the seal, including its faces, set screws, springs and various related components.

Even after water blasting, certain contaminants may be too hard to remove, in these cases glass bead blasting removes hard contaminants from the metal surface of the seal, leaving it pristine.

With extensive use, seal faces will eventually become textured from being ground which undermines their effectiveness. Because of this, a face lapping process is necessary to keep their surfaces smooth. This can either be done with course, ground or fine face lapping.

Even though the seal is so much closer to being ready for repurposing, there may still be some associated component which have suffered too much damage to be restored properly. At this point in the repair process, any associated spares and replacements are sourced or manufactured and fitted to the seal.

After spare parts have been replaced, the seal needs to be completely assembled and thoroughly tested to ensure the effectiveness of the repair process. From this point it is ready to be passed on to the customer or fitted to their machinery to ensure economic operations.
