Reconditioning of mechanical seals
Mechanical seals are subject to wear caused by their operating principle. The amount of damage essentially depends on the individual operating conditions. In many cases mechanical seals may be reconditioned by professional work into a condition as good as new.
Due to prior damage analysis unfavourable operating conditions will be recognized. On request qualified modifications on the seal may be recommended to extend the operating life time.

General hints
METAX will carry out repair services for any type of seal independent of the manufacturer. For complete cartridge seals an assembly drawing should be included if possible.
To make a complete analysis of damage all operating parameters should be available. Delivery of complete new seal if ofren more economic on small sizes.
Reconditioning is only possible when receiving all parts. Chemical neutralization, if necessary, should be carried out prior to shipment. Packing should be carried out carefully. Especially seal faces should be protected against mechanical shock loads.
