DANGER
Insufficient preparation of work on the pump (set)
Risk of injury!
▷ Properly shut down the pump set. (
ð
Section 6.1.7, Page 38)
▷
Close the shut-off elements in suction and discharge line.
▷ Release pump pressure.
▷ Close any auxiliary connections.
▷
Allow the pump set to cool down to ambient temperature.
WARNING
Fluids handled, consumables and supplies which are hot and/or pose a health
hazard
Hazard to persons and the environment!
▷ Collect and properly dispose of flushing fluid and any fluid residues.
▷
Wear safety clothing and a protective mask if required.
▷ Observe all legal regulations on the disposal of fluids posing a health hazard.
If the pump set has handled fluids whose residues could lead to corrosion damage in
the presence of atmospheric humidity or could ignite upon contact with oxygen, the
pump set must be neutralised, and anhydrous inert gas must be blown through the
pump to ensure drying.
Use connection 6B to drain the fluid handled (see drawing of auxiliary connections).
The pump is drained via drain plugs 903.01 (on the casing) and 903.80 (on the casing
cover, if any).
With dead-end configuration, also open connection 5B after removing drain plug
903.80 to drain the heat exchanger and the magnetic coupling. Use connection 5B
for flushing the heat exchanger and the magnetic coupling with dead-end
configuration.
NOTE
Apart from the pump casing itself, the bearing bracket lantern 344, too, could be
pressurised (on models fitted with a leakage barrier).
In the event of a defective
containment shroud
To avoid any risk in the event of damage to the containment shroud, also always
open screw plugs 903.22 and 903.94 on the bearing bracket lantern (or remove
auxiliary pipework, if any), to ensure that the fluid handled is drained completely.
If handling highly toxic
fluids
Utmost care must be taken when highly toxic fluids have been handled. In this case,
the complete pump set must be thoroughly flushed through.
Always watch out for possible liquid residues even when the pump has been flushed
and drained!
