MAINTENANCE
Before dismantling or doing any operation on the regulator, it is essential to decompress the
material, to avoid any serious injury that may be caused by product splashing into the eyes or
being injected under the skin and causing blood poisoning.
Maintenance consists in checking the seals and diaphragms as well as the all parts of the
regulator consequently to some leaks or just for preventive maintenance.
It is advisable to replace the parts showing an unusual wear.
BRINGING THE EQUIPMENT INTO SERVICE
The regulators are tested in our workshops with a neutral lubricant.
Before putting the equipment into service you have to rinse the lubricant with a solvent (naphta
or chlorinated solvent for example), if it is not compatible with the product to be pumped.
