DESCRIPTION
3.1 Design
3.2 Area of Application
The ROTILABO
®
CR-DS 40 vacuum pumps are oil-sealed, two-stage Rotary vane pumps.
The drive motor is directly flange-mounted onto the motor cover of the pump holder and
the pump shaft and the motor shaft are connected to each other by an elastic coupling.
The bearings of the interior pump body are force-fed lubricated sliding bearings.
The range of application of our oil-sealed Rotary vane pumps encompasses the entire field of
vacuum technology, both for use in the laboratory and in industry.
The task is to create an ultimate pressure of 10
-3
mbar (ultimate pressure partial 10
-4
mbar):
•
As a single vacuum pump
•
As a fore-vacuum pump for oil diffusion pumps or as turbomolecular pumps
The rotary vane pump can evacuate containers or vacuum installations up into the high vacuum range.
