Risk of material damage caused by improper storage!
▶ Store the aggregate accordingly.
1. Close all openings with blank fl anges, plugs or plastic
covers.
2. Make sure the storage room meets the following
conditions:
− dry
− frost-free
− vibration-free
− protected
− constant humidity
3. Turn the motor shaft once per month.
4. Make sure the motor shaft and bearing change their
rotational position in this process.
4.3 Preservation
Not necessary for rust-proof material

Risk of material damage caused by improper storage!
▶ Properly apply preserving agent to the inside and
outside of the aggregate.
1. Select a preserving agent in accordance with the type
and duration of storage (→ page 31).
2. Use preserving agents in accordance with the
manufacturer's specifi cations.
3. Coat all bare metal components positioned inside and
outside the pump with preserving agent.
4. Treat the impeller gap with a preserving agent.
4.3.1 Preservation inside the system
C AU T I O N
Risk of material damage caused by improper
preservation!
▶ Shut down the aggregate (→ Shut-down, page 19).
Use appropriate collecting trays. Position of drainage
bores (Ue) (→ Dimensional drawings, page 32 et seq.).
•
Unscrew the screw plugs of all drainage bores (Ue).
•
Drain the operating liquid (water).
•
Occasionally rotate the motor shaft towards the
direction of rotation of the aggregate.
•
Continue with this process until no more liquid
escapes.
•
Plug all drainage bores with screw plugs.
•
Remove the pipes from the suction, pressure and
process water connections.
•
Plug the outlet nozzle and the process water connection
by means of blank fl anges/screw plugs.
•
Fill in preserving agent into the open inlet nozzle.
Observe the fi lling volumes (→ Filling volumes
preservation, page 31).
•
Plug the inlet nozzle with a blank fl ange/screw plugs.
•
Switch the aggregate shortly on and off to allow for a
proper distribution of the preserving agent.
•
Unscrew the screw plugs of all drainage bores (Ue) and
the operating liquid connection (UB).
•
Drain the preserving agent into collecting trays.
•
Occasionally rotate the motor shaft towards the
direction of rotation of the aggregate.
•
Continue with this process until no more preserving
agent escapes.
•
Close the suction, pressure and operating liquid
connection (UB) using transport or sealing covers.
•
Plug all drainage bores (Ue) with screw plugs.
4.3.2 Preservation outside the system
Risk of material damage caused by improper
preservation!
▶Shut down the aggregate (→ Shut-down, page 19; Return
to manufacturer, page 21).
Use appropriate collecting trays. Position of drainage
bores (Ue) (→ Dimensional drawings, page 32 et seq.).
•
Plug all drainage bores (Ue) with screw plugs.
•
Close the operating liquid connection (UB) using a
blank fl ange/screw plug.
•
Fill in preserving agent into the open inlet or outlet
nozzle until the agent becomes visible. Observe the
fi lling volumes (→Filling volumes preservation, page
31).
•
Occasionally rotate the motor shaft towards the
direction of rotation of the aggregate.
•
Continue this process until the preserving agent
appears approx. 30 mm below the upper edge of the
inlet/outlet nozzle.
•
Unscrew the screw plugs of all drainage bores (Ue) and
the operating liquid connection (UB).
•
Drain the preserving agent into collecting trays.
•
Occasionally rotate the motor shaft towards the
direction of rotation of the aggregate.
