3.3 Operating
conditions
Temperatures
max. permissible temperature:
+40 °C
[+104 °F]
Nominal value:
+15 °C
[+59 °F]
Temperature of
Pump-motor units for higher
fluid temperatures on request.
max. permissible temperature:
+40 °C
[+104 °F]
min. permissible temperature:
-30 °C
[-22 °F]
Nominal value:
+25 °C
[+77 °F]
Ambient
temperature
(standard
design)
Ambient temperatures between
25 °C [+77 °F] and 40 °C
[+104 °F] affect the permissible
total pressure difference (see
Section "Permissible total
pressure difference").
At higher temperatures the
winding may be damaged and
the grease change interval may
be shortened.
Pressures
Min. inlet
pressure:
See rating plate.
Max. discharge
pressure during
compressor
operation:
See rating plate.
Max.
permissible
pressure in
pump-motor
unit:
2.5 bar abs. [36.2 psia]
At this pressure the operation of
the pump-motor unit may be
considerably impaired.
Provide a corresponding
protective device (e.g. pressure
relief valve) if necessary.
