4.2 Storage
Pumps/aggregates treated by the factory have been provided
with an anticorrosive coating. When properly stored indoors, the
pump/aggregate is protected for a maximum of 3 months. In
case of longer storage periods, the pump/aggregate has to be
treated with a preserving agent again (
4.3 Preservation).
For storing pumps/aggregates which have already been in use,
the preparations specified in Paragraph 4.3 Preservation must
be made.
Applied preserving agents (
page 45)
CAUTION
Risk of material damage caused by improper storage!
►
Store the pump/aggregate accordingly.
1.
Close all openings with blank flanges, 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 pump shaft once per month.
4.
Make sure the pump shaft and bearing change their rota-
tional position in this process.
4.3 Preservation
Not necessary for rust-proof material
CAUTION
Risk of material damage caused by improper preservation!
►
Properly apply preserving agent to the inside and outside of
the pump.
1.
Select a preserving agent in accordance with the type and
duration of storage (
page 45)
2.
Use preserving agents in accordance with the manufac-
turer's specifications.
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
CAUTION
Risk of material damage caused by improper preservation!
►
Shut down the aggregate (
Shut down, page 20)
Use appropriate collecting trays, position of drainage bores
(U
e
, U
e1
) (
Dimension drawings, page 46 et seq.)
•
Unscrew the screw plugs of all drainage bores (U
e
, U
e1
).
•
Drain the operating liquid (water).
•
Occasionally rotate the pump shaft/motor shaft towards the
direction of rotation of the pump.
•
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 flanges/screw plugs.
•
Fill in preserving agent into the open inlet nozzle. Observe
the filling volumes.
(
Filling volumes for preservation, page 45).
•
Plug the inlet nozzle with a blank flange.
•
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 (U
e
) and the
operating liquid connection (U
B
).
•
Drain the preserving agent into collecting trays.
•
Occasionally rotate the pump shaft/motor shaft towards the
direction of rotation of the pump.
•
Continue with this process until no more preserving agent
escapes.
•
Close the suction, pressure and operating liquid connection
(U
B
) using transport or sealing covers.
•
Plug all drainage bores (U
e
, U
e1
) with screw plugs.
4.3.2
Preservation outside the system
CAUTION
Risk of material damage caused by improper preservation!
►
Shut down the aggregate (
Shut-down, page 20; Return to
manufacturer, page 22)
Use appropriate collecting trays, position of drainage bores
(U
e
, U
e1
) (
Dimension drawing, page 46)
•
Plug all drainage bores (U
e
, U
e1
) with screw plugs.
•
Close the operating liquid connection (U
B
) using blank
flanges/screw plugs.
•
Fill in preserving agent into the open inlet or outlet nozzle
until the agent becomes visible. Observe the filling volumes
(
Filling volumes for preservation, page 45).
•
Occasionally rotate the pump shaft/motor shaft towards the
direction of rotation of the pump.
•
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 (U
e
) and the
operating liquid connection (U
B
).
•
Drain the preserving agent into collecting trays.
•
Occasionally rotate the pump shaft/motor shaft towards the
direction of rotation of the pump.
•
Continue with this process until no more preserving agent
escapes.
•
Close the suction, pressure and operating liquid connection
(U
B
) using transport or sealing covers.
•
Plug all drainage bores (U
e
, U
e1
) with screw plugs.
