Stopping the Pump<br />
Stopping the Pump<br />
There are no special procedures for switching the pump off; it needs<br />
only to be disconnected from the electric power by means of the<br />
bipolar switch.<br />
When the pump is stopped, the anti-suckback device makes it<br />
possible to maintain vacuum in the vessel connected on the inlet<br />
flange of the pump.<br />
If the pump is expected to be stopped for a lengthy period, or in any<br />
case if it has pumped in large amounts of vapors, it is good practice<br />
to run it with the gas ballast open and the inlet line closed for a few<br />
minutes before switching off in order to limit the risk of corrosion or<br />
scaling due to pollution of the oil by condensed vapors.<br />
