The suction and pressure joints must be considered
separately.
If not all loads in effect reach the value limits, one of
these loads may exceed the usual value limit by 1.4
times. The following requirement must be observed

3.5 Permitted Pressures and Temperatures
In principle, the pressure and temperature values
given in the datasheet and/or order confirmation as
well as the performance label apply. Values (for
pressure and temperature) exceeding these values or
falling below them (for temperature) are not permitted.
If no pressures and/or temperatures are specified in
the data sheet and/or the order confirmation, the
following limits apply for supply pressure and room
temperature:
Supply pressure (system pressure) = Pressure at
the pump intake:
max. 10 bar
Room temperature: max. 40°C
Also obey the applicable laws and regulations when
using the pump (e.g. DIN 4747 or DIN 4752).
Limit Curve as per EN 1092
Max. permissible operating pressure (casing and
flange) applies for the material codes:
F, FB, FN
Limit Curve as per EN 1092
Max. permissible operating pressure (casing and
flange) applies for the material codes:
