With double-stage rotary vane vacuum pump TRIVAC, resp. single-stage rotary vane vacuum pump SOGEVAC
(Type of backing pump look at max. pumping speed). When using 2-stage backing pumps the ultimate pressures will be
correspondingly lower
4)
Applicable for ratio up to 1 : 4 between backing pump and Roots vacuum pump at 3000 rpm
5)
Upon request also available with a max. speed of 6000 rpm (see table “differential pressures” in Section 1.3.2
and part nos. for 100 Hz versions of the WS(U) 2001

9)
The minimum permissible speed is relevant for the oil lubrication system of bearings and gears and has to be considered if the speed
is constant for more than 1 hour. Running the pump at less than the minimum speed for more than 1 hour can cause damage to the
pump due to a lack of lubrication.
