Technical data
2.3 General data/operating conditions
Conformity
CE Low−Voltage Directive
Vibration resistance
Acceleration resistant up to 2g (Germanischer Lloyd, general conditions)
Vibration velocity
max.
v
eff
4 mm/s [0,013 ft/s] Depending on the application case and the
system type it may be necessary to use vibration
dampers.
Site altitude
min. 0 m üNN [0 ft amsl]
max. 1000 m üNN [3280 ft amsl] For installations above 1000 m amslA [3280 ft
amsl] consultation of the manufacturer is
required.
Climatic conditions
Class 3K3 to EN 50178 (without condensation, relative humidity 30 ... 95 %)
Ambient temperatures
Transport min. -25°C [-13°F]
max. +70°C [+158°F]
Storage min. -25°C [-13°F]
max. +60°C [+140°F]
Operation min. -20°C [-4°F]
max. +40°C [+104°F]
rated value +25°C [+77°F]
Between +25 °C [+77 °F] and +40 °C [+104 °F]
reduce the total pressure difference indicated on
the rating plate by 0.7 %/°C [0.4 %/°F].
Operation at higher temperatures may damage
the winding and shorten the grease change
interval.
Temperature of pumped gases
max. +40°C [+104°F]
rated value +15°C [+59°F]
Pump−motor units for higher media
temperatures Pump on request.

Permissible total
pressure difference
max. See rating plate The total pressure difference specified on the
rating plate only applies under the following
conditions:
 Ambient temperature: 25 °C [77 °F]
 Temperature of the pumped gas at the inlet
connection: 15 °C [59 °F]
 Pressure:
– for vacuum−pump operation: 1013 mbar
[14.7 psia] at the discharge connection
– for compressor operation:
1013 mbar [14.7 psia] at the inlet
connection

Aggregat
max. 2 bar abs. [29 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.
