Timing gear
The rotors are driven synchronously and exactly through the car-
rier shafts by two gear wheels.
The shafts of the rotary lobe pump are seated on one side inside
the carrier gear unit.
As the gear unit is completely separate from the pump chamber,
disassembly is not necessary for any maintenance work.
Depending on the ordered version, the drive shaft is installed in
position 0 or position 1.
The rotary lobe pump can also be delivered with two drive shafts,
e.g. a rotary lobe pump driven mechanically by means of the PTO
shaft, where the direction of rotation can be changed by switching
the PTO shaft.
The timing gear is equipped with a breather system to compensate
for increased pressure due to rising temperatures. The breather
system must always be installed on the highest point of the rotary
lobe pump, compare the illustrations of the versions for the dif-
ferent mounting positions in
Chapter 3.1.7 “Designs, mounting
.
3.1.5
Shaft seal
Börger rotary lobe pumps are equipped as standard with mechan-
ical seals designed specifically for this pump type. These are used
to completely seal off the pump chamber from the gear unit, or
from the intermediate chamber (see
). These seals can be quickly
accessed through the working chamber without removing the
machine, and can be replaced easily.
