3. Characterization of vacuum pumps
All vacuum pumps can be characterized by measurable quantities, the main ones being :
Volume flow rate or pumping speed ;
suction limit pressure ;
maximum compression ratio ;
maximum critical discharge pressure ;
maximum discharge pressure.
These characteristics are not totally independent of one another (see § 3.3 ).
