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:
