6.2 Operating limits
DANGER
Non-compliance with operating limits for pressure, temperature, fluid handled and
speed
Hot fluids escaping!
▷ Comply with the operating data indicated in the data sheet.
▷ Avoid prolonged operation against a closed shut-off element.
▷
Never operate the pump at product temperatures exceeding those specified in
the data sheet or on the name plate.
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 7: Permissible ambient temperatures specified for the fluid temperature
Fluid temperature Permissible ambient temperature
[°C] [°C]
≤ +110 +40
≥ +2 0
6.2.2 Minimum inlet pressure
The minimum inlet pressure p
min
at the pump suction nozzle serves to avoid cavitation
noises at an ambient temperature of +40 °C and the indicated fluid temperature T
max
.
The indicated values are applicable up to 300 m above sea level. For installation at
altitudes > 300 m, an allowance of 0.01 bar / 100 m must be added.

6.2.3 Maximum operating pressure
CAUTION
Permissible operating pressure exceeded
Damage to connections and seals!
▷ Never exceed the operating pressure specified in the data sheet.
