NOTE
If the discharge line is equipped with a non-return or check valve, the shut-off
element may remain open provided that the system conditions and system
regulations are considered and observed.
For prolonged shutdown periods:
1. Close the shut-off element in the suction line.
2. Drain all fluids which tend to polymerise, crystallise, solidify, etc. from the pump
and the magnetic coupling.
3. Flush the pump set with a suitable liquid if necessary.
If the pump was used for handling fluids posing a health hazard, observe the
information for draining the pump set. (
ð Section 7.3, Page 50)
4. Close the auxiliary feed lines.
Do not turn off the cooling liquid supply, if any, until the pump has cooled
down.
CAUTION
Risk of freezing during prolonged pump shutdown periods
Damage to the pump!
▷ Drain the pump and the cooling/heating chambers (if any) or otherwise protect
them against freezing.
6.2 Operating limits
DANGER
Non-compliance with operating limits for pressure, temperature, fluid handled and
speed
Explosion hazard!
Hot or toxic fluid could escape!
▷ Comply with the operating data indicated in the data sheet.
▷
Never use the pump for handling fluids it is not designed for.
▷ Avoid prolonged operation against a closed shut-off element.
▷ Never operate the pump at temperatures, pressures or rotational speeds
exceeding those specified in the data sheet or on the name plate unless the
written consent of the manufacturer has been obtained.
DANGER
Formation of a potentially explosive atmosphere inside the pump
Explosion hazard!
▷
When draining tanks take suitable measures to prevent dry running of the
pump (e.g. fill level monitoring).
6.2.1 Ambient temperature
CAUTION
Operation outside the permissible ambient temperature
Damage to the pump (set)!
▷ Observe the specified limits for permissible ambient temperatures.
Observe the following parameters and values during operation:
