If the specified maximum temperatures are
complied with, the units are suitable for
temperature class T3.
G-BH1 unit operating liquid
 WARNING
The ignition temperature of the operating fluid
must be above 150°C [150.00°F].
The chosen operating liquid must comply with
the requirements / properties stated below.
It must not corrode or destroy the pump
components used.
 WARNING
Monitoring of the operating liquid status before
starting up as well as monitoring of trouble-free
feeding of the operating liquid while in operation
should be built into the system.
The system must shut down if there is a failure
in the operating fluid feed.
Operating without operating fluid must be
avoided under all circumstances.
NOTE
When using operating fluids with a heat capacity
of < 3 kJ/kg K, or a boiling point which does not
lie 20 K above the input temperature, consult
the manufacturer.
Operating liquid type:
Normally use water with a pH-value between 6
and 9, or any other liquid compatible with the
process.
It must be free of:
− Foreign matter and objects:
−
Crystalline precipitate substances
− Substances which tend to stick or jam
No precipitate substances may be produced from
the operating fluid during the sealing process.
Likewise, no substances may be used which tend
to polymerise of their own accord or when in
contact with propellant gas.
Compatibility must be checked with regards to
chemical reactions between the operating liquid
and the slide ring seal, the operating fluid and
other pump parts as well as the operating fluid
and the propellant gas.
Foreseeable misuse
The following are forbidden:
 Use of the unit2BV2 060 2BV2 061 2BV2
070 2BV2 071 2BV5 110 2BV5 111
2BV5 121 2BV5 131 2BV5 161 in non-
industrial plants, unless the necessary
precautions and protective measures have
been taken at the plant, e.g. protection
against contact by children's' fingers.
 Setting up and use of units in zones 0, 20, 21
and 22.
 The extraction, transport and condensing
of aggressive or poisonous media unless the
units are specifically designed for such media.
 to evacuate, convey and compress explosive,
inflammable, or aggressive mediums, which
could damage the slide ring seal.
 To evacuate, convey and compress gases or
gas mixtures which are explosive when air is
not present, or may change the unit’s safety-
relevant material properties.
 Operation with a frequency converter.
 Operation of the unit at any values other than
those specified in chapter 3 “Technical data”
in the 610.44440.40.000 operating manual.
Modifications to the units are forbidden for safety
reasons.
The operator is not allowed to carry out
maintenance, servicing and repair work which
requires the machine to be dismantled.
