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.
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:
Table 9: Permissible ambient temperatures

See data sheet.
6.2.2 Frequency of starts
DANGER
Excessive surface temperature of the motor
Explosion hazard!
Damage to the motor!
▷
In case of explosion-proof motors, observe the frequency of starts specified in
the manufacturer's product literature.
The start-up frequency is usually determined by the maximum temperature increase
of the motor. This largely depends on the power reserves of the motor in steady-
state operation and on the starting conditions (DOL, star-delta, moments of inertia,
etc). If the start-ups are evenly spaced over the period indicated, the pump set can be
started up six times per hour (h) with the discharge-side gate valve slightly open.
CAUTION
Re-starting while motor is still running down
Damage to the pump (set)!
▷
Do not re-start the pump set before the pump rotor has come to a standstill.
