Operation; Suction Of Condensable Gases; Work Cycle - Vuototecnica Rvp 21 Betriebs- Und Wartungshandbuch

The oil bath or oil recirculation vacuum pumps can pump both non-
condensable and condensable gases.

Suction of condensable gases

In a pump with oil recirculation lubrication, an increase
of the oil level in the tank can be a sign of the presence
or excess of condensable gases.
The presence of condensables gases inside the pump
can cause its components to corrode as well as a
residual risk to the operators.

Work cycle

It is recommended not to exceed a maximum of 10 start ups/hour.
In case of heavier work cycles, it is recommended that the pump is left
to run continuously and an electrically or pneumatically controlled valve
is installed on the suction line.
At the end of the work cycle, it is recommended that
you leave the pump to run for around five minutes
with the suction hole closed in order to get rid of the
condensables in the pump.
