Maintenance of the systems
The maintenance operations of the seal organs must be carried out reserving the maximum amount of care to avoid damaging the O-Rings. The products used for cleaning must be absolutely compatible with the compound of the O-Rings installed. The disassembly and assembly operations must be carried out with the maximum amount of care to avoid running into difficulties described in the previous paragraphs.
The cleaning operations can bring some impurities to install themselves inside the O-Ring housing and remain there. These impurities can damage the ring once restarting the system. It is a good rule to install a protection to the O-Ring, appropriate filters in all of those circuits in which it is not possible to exclude the presence of solid impurities in the fluid.
