DANGER
Risk of ignition by frictional sparks
Explosion hazard!
▷ Choose a coupling guard material that is non-sparking in the event of
mechanical contact (see DIN EN 13463-1).
6. Fit the coupling guard and its footboard, if any.
7. Check the distance between coupling and coupling guard.
The coupling guard must not touch the coupling.
5.10 Checking the lubricants
Grease-lubricated bearings
Grease-lubricated bearings have been packed with grease at the factory.
Lubricant supply for mechanical seals
The lubricant reservoirs have been filled at the factory.
Check the lubricant level before commissioning the pump set.
Fig.16: Checking the lubricant level
ü The pump set has been installed as specified.
1. Unscrew and remove screw plug (1) with joint ring (2).
2. If the lubricant level is within the 10 mm tolerance range below the opening, re-
insert and fasten screw plug (1) with joint ring (2).
3. If the lubricant level is below the tolerance range, fill in more lubricant.

5.11 Barrier fluid connection
Suitable barrier or flushing liquids are the fluid handled, which has been cleaned or
cooled if required, or a cleaned external liquid of which small quantities may mix
with the fluid handled. If no barrier fluid is available, grease can be pressed in as a
substitute.
Install the correct connection for the type of barrier fluid used.
