8.2 Preparations for long-term shutdown
For longer shutdown periods (from approx.
4 weeks) or in the event of frost hazard proceed
as follows:
Cast iron construction:
 Drain down the unit as described in chap-
ter 8.1, "Draining down", page 23.
 Remove the piping / hoses from the suction
and discharge connections.
 Pour a preserving agent (anti-rust oil, e.g.
Mobilarma 247 supplied by the Mobil Oil Co.)
into the open suction and discharge connec-
tions.
Charge required:
for 2BV2 …:
½ l [0.132 gal (US); 0.110 gal (UK)]
For 2BV5 …:
1 l [0.264 gal (US); 0.220 gal (UK)]
 Seal off the suction and discharge connec-
tions as well as the operating-liquid connec-
tion or alternatively reinstall the piping / hoses.
 Start and stop the unit briefly to distribute the
preserving agent.
 There are two alternatives for storage:
- the unit remains connected up to the sys-
tem,
- or the unit is removed and stored sepa-
rately.
Stainless steel and bronze constructions:
 Drain down the unit as described in chap-
ter 8.1, "Draining down", page 23.
 There are two alternatives for storage:
- the unit remains connected up to the sys-
tem,
OR
- or the unit is removed and stored sepa-
rately.
8.3 Storage conditions
This chapter applies to:
 new units,
 units that have been prepared for long-term
shutdown as described in chapter 8.2,
"Preparations for long-term shutdown",
page 24.
In order to avoid damage during shutdown and
storage periods, the ambient conditions should
be as follows:
 dry,
 free of dust,
 low vibration (effective value for the speed of
oscillation veff ≤ 2.8 mm/s [0.11"/sec]).
 ambient temperature:
max. +40 °C [+104 °F].
CAUTION
Risk of material damage due to high tem-
peratures!
Storage at ambient temperatures in excess of
40 °C [104 °F] can result in damage to the wind-
ings and reduced re-greasing intervals.
8.4 Commissioning after a long shutdown
period
CAUTION
Risk of material damage due to insufficient
lubrication of roller bearings after long term
storage!
 If the unit is stored for a period of more than
2 years then the roller bearings will require
new greasing (see Re-grease or renew roller
bearings, page 27).
 Drain off the preserving agent (chapter 8.1,
"Draining down", page 23).
No further cleaning of the unit is necessary.
 Dispose of the preserving agent in accor-
dance with the manufacturer's recommenda-
tions.
 In the event that the impeller does not rotate
freely:
Decalcifying the unitt or To free it, rotate the
shaft (chapter 9.1, "Maintenance", page 26).
 For new units proceed as described in chap-
ter 5, "Installation", page 14.
 For units having been shut down for long pe-
riods proceed as described in chapter 6
"Commissioning", page 14.
