▷

Only open screw plugs and connections at the mechanical seal at the time of

Avoid opening screw plugs, connections and similar before that time.

We recommend taking the following measures for storing the mechanical seal:

For storing the mechanical seal observe standards ISO 2230 and DIN 7716.

Store the mechanical seal in its original packaging, placed on a level surface in a dry,
protected room with constant conditions that meet the following requirements:

▪

Relative humidity < 65 %

▪

Temperature between 15 °C and 25 °C

▪

Moderately vented atmosphere

▪

Dust-free and vermin-free

If properly stored indoors, the equipment is protected for a maximum of 36 months.
New mechanical seals are supplied by our factory duly prepared for storage.

3.4 Return to supplier

1. Remove the used mechanical seal from the system.

2. Always flush and clean the mechanical seal, particularly if it has been used for

handling noxious, explosive, hot or other hazardous fluids.

3. If the mechanical seal has handled fluids whose residues could lead to corrosion

damage in the presence of atmospheric humidity or could ignite upon contact
with oxygen, the mechanical seal must also be neutralised and dried with
anhydrous inert gas.

4. Always complete and enclose a certificate of decontamination when returning

the mechanical seal. Always indicate any safety measures and decontamination
measures taken.
