Start-up
Each time before starting up check the oil level.
Open all valves blocking the exhaust lines. The pump must never
be operated with a blocked or constricted exhaust line.
For pumps with 3-phase motors, check the direction of rotation before star-
ting the pump for the first time and after each change in the electrical
connection (see Chapter 3.4).
On initial start-up, after prolonged idle periods or after an oil change, the
specified ultimate pressure cannot be attained until the oil is degassed.
This can be done by running the pump for approx. 30 min. with the intake
line closed and the gas ballast valve (7/5) open.
If the chemical filter (CFS) has been installed on the pump the separating
valve may be set to the position marked “Wechsel” during the first part of
the run-up phase. When doing so, the relatively cold and thick lubricant will
not have to be pumped through the interchangeable filter, thus removing
some load from the pump’s motor. Thereafter, the separating valve is set to
the position “Betrieb”.
Before starting the pump ensure that the pump and the fitted
accessories meet the requirements of your application and that
safe operation can be guaranteed.
Avoid exposure of any part of the body to the vacuum. There is
the danger of injury. Never operate the pump with an open intake
port. Vacuum connections as well as oil-fill and oil-drain openings
must never be opened during operation.
The safety regulations which apply to the application in each case
must be observed. This applies to installation, operation and
during maintenance (service) as well as waste disposal and trans-
portation.
The standard pump is not suited for pumping of hazardous gases
or vapours.
Our technical sales department is available for further advice in these mat-
ters.
