HS452, HS652 Rotary Vane Pumps User Manual / 87-900-978-01 (H) 69/102
NOTE
If gases without vapors are sucked in, you are advised to open the gas ballast
device from time to time in order to eliminate the traces of humidity they
contain.
NOTE
For repetitive work cycles, with brief time intervals in between, it is better not to
stop the pump.
Stopping the Pump
There are no special procedures for switching the pump off; it needs
only to be disconnected from the electric power by means of the
bipolar switch.
When the pump is stopped, the anti-suckback device makes it
possible to maintain vacuum in the vessel connected on the inlet
flange of the pump.
If the pump is expected to be stopped for a lengthy period, or in any
case if it has pumped in large amounts of vapors, it is good practice
to run it with the gas ballast open and the inlet line closed for a few
minutes before switching off in order to limit the risk of corrosion or
scaling due to pollution of the oil by condensed vapors.
