G-BH1 units
 are equipped with RL 94/9/EG three-phase
drive motors. For more detailed information
please consult the motor manufacturer’s
accompanying operating instructions.
 exist in the following formats:
− single-impeller
− two-impeller, two-stage (for increased
pressure difference)
− two-impeller, double flow. (for increased
conveyance volumes).
 are designed for industrial plants.
 are designed for continuous operation.
When operating the units, observe the limit
values and following scope of application listed in
chapter 3, “Technical data” of instruction manual
610.44434.40.000.
Scope of Application.
Inside area of explosion prevention design
G-BH1 units are suitable for conveying gases
and dusts where under normal operating
conditions a potentially explosive atmosphere is
not expected to be present. If it does occur
however, then only temporarily.
This specification includes category 3G and 3D
for the internal space of the units.
Inside area biogas use
G-BH1 units are suitable for conveying gases
with a relative humidity of up to 80% and dusts
where under normal operating conditions a
potentially explosive atmosphere is not expected
to be present. If this should however arise, it will,
in all probability, only be temporary.
This specification includes category 3G and 3D
for the internal space of the units.
Surrounding area
When rating the device category, both the place
where it is installed and its internal space must
be taken into consideration.
Installing G-BH1 units for categories 3/2G and
3/2D is allowed for areas where potentially
explosive gases and dusts are expected to occur
occasionally.
The use of G-BH1 units for category 3G and 3D
is allowed in areas where no potentially explosive
atmosphere is present. If it does occur however,
then only temporarily.
Foreseeable misuse
 WARNING
Danger of explosions!
Gases, gas mixtures and dusts which are
explosive when air is not present, or may
change the machine’s safety-relevant material
properties, must not be conveyed.
It is forbidden:
 to use the unit for non-industrial facilities
unless essential precautions and protection
measures are fitted, such as guards to protect
children's fingers;
 to use the unit for category 3/2GD in areas
where explosive gases and dusts occur
constantly, frequently, or for long periods of
time;
 to use the unit for category 3GD in areas
where explosive gases and dusts occur
constantly, frequently, or for long periods of
time;
 to evacuate, convey and compress explosive,
inflammable, or aggressive mediums;
 to operate the unit using limits other then
those stipulated in chapter 3 “Technical data”,
p.8 and following pages in the standard
operating manual;
 in biogas uses:
− to draw in from explosive areas, or
discharge into explosive areas.
Unauthorised modifications to the units are
forbidden due to safety reasons.
The operator is not allowed to carry out
maintenance, servicing and repair work which
require the machine to be dismantled.
