Accessories
The range of accessories supplied by Börger GmbH is as multi-
faceted as the areas of application for Börger machines. Only the
most frequently requested equipment can be mentioned below.
If your Börger machine was delivered with accessories, the
corresponding operating manuals can generally be found in
the appendix or in the packaging of the units, if delivered as
originally packed.
8.1
Frequency converter
The machine can be operated with a frequency converter. Only fre-
quency converters that deliver a constant torque are suitable for
the Börger machine.
NOTE!
External drive cooler
An external drive cooler may be necessary if the motor frequency
is set very low.
8.2
Monitoring equipment
8.2.1
Dry run protection
Long dry run periods (i.e. operation without pumped medium)
should be avoided. This especially applies to rotary lobe pumps
with rubber-coated rotors. Components on the rotary lobe pump
are damaged when frictional heat is generated.
In processes in which dry running cannot be fully excluded, e.g.
when containers are emptied using the rotary lobe pump, dry run
protection is recommended through the temperature monitoring
device or a conductivity sensor as a level control indicator, both in
combination with a connected controller.
You can obtain the PT100 temperature sensors and control units
from Börger GmbH.
