3.1 Function
The operating principle of the
HiLobe
roots pump is based on 2 synchronous pistons that rotate in a
housing without touching. The pumping effect is produced as a result of the opposing rotation of 2 fig-
ure-of-eight shaped roots pistons. While suction chambers are formed between the rolling pistons and
the housing, the rolling pistons continuously form a mutual seal without touching each other or the hous-
ing. A pair of gears positioned on the extended shaft ends, causes the opposing, synchronous running
of the roots pistons. Lubrication is limited to the two bearing and gear chambers which are arranged
separately from the suction chambers.
