4.4 Description
The TWISTER S-VSI is a twin-screw vacuum pump in which two parallel screw rotors roll off against each
other contactless and dry. The gas to be fed in is hereby enclosed in the pump's suction chamber and com-
pressed by the rotary movement of the screw rotors in the direction of the outlet. The gas sucked in is grad-
ually compressed to atmospheric pressure. The counter-rotating screw rotors are synchronised by a gear
pair in the gearbox. The gears of the synchronized gearbox and the bearings are lubricated with oil. These
components are in a gearbox that also contains the oil supply. Oil conveying devices always ensure that the
bearings and the gears are sufficiently supplied with oil at all permissible speeds.
The gearbox and the compression chamber are separated from each other by special seals. The gearbox is
sealed from the outside with piston sealing rings and O-rings, the compressor chamber with piston rings.
The TWISTER S-VSI is driven by standard flanged three phase motors via a clutch (with an elastomer
component).
To be able to distinguish them from the standard variants, the VSI OXY pumps are blue painted.
