Table 15: Key to the symbols and codes
Symbol Description
FD
Always apply a liquid sealant (e.g. Hylomar SQ32M) to sealing surfaces
marked with this symbol.
ü
A suitable container for the leakage is on hand.
ü The pump is positioned horizontally on a level surface and is protected against
rolling off.
1. Place the container underneath screw plug 903.02.
2. Remove screw plug 903.02 and joint ring 411.02.
3. Screw in a sufficiently long G 1/2 tube (1).
4. Carefully rotate the pump set until the opening of the leakage chamber points
downwards.
ð If there is no leakage or only a small amount (less than 1.5 litres) after several
years of operation, the mechanical seals are working properly. If the leakage
exceeds 1.5 litres, the mechanical seals are defective and must be replaced.
5. Unscrew the tube (1).
6. Fit screw plug 903.02 together with a new joint ring 411.02.
7.4 Lubrication and lubricant change
7.4.1 Lubricating the mechanical seal
DANGER
Excessive temperatures at the shaft seal
Explosion hazard!
Damage to the pump set!
▷ Regularly check the condition of the lubricant in the lubricant reservoir of the
mechanical seal. Top it up if required.
The mechanical seal is supplied with lubricant from the lubricant reservoir.
7.4.1.1 Intervals
Replace the lubricant every 8000 operating hours but at least every 3 years.
7.4.1.2 Lubricant quality
The lubricant reservoir is filled at the factory with an environmentally friendly, non-
toxic lubricant of medical quality (unless otherwise specified by the customer). The
following lubricants can be used to lubricate the mechanical seals:
