4.2 Description
The S-VSI model range has threaded connections on the suction and discharge ports.
The VSI is an oil-free double shaft screw vacuum pump in which two parallel screws mesh with each other
without contact. The gas flows into the pump’s suction chamber and compressed by the rotary movement
of the screw rotors in the direction of the outlet. Due to our continuously variable pitch screw design, the
gas is drawn in and is gradually compressed to atmospheric pressure. The counter-rotating screw rotors are
synchronised by a set of gears. The synchronous gears and bearings are splash-lubricated with oil.
The gearbox and the compression chamber are separated from each other by special seals. The gearbox is
sealed from the outside with shaft seals and O rings, as well as the compression chamber with piston rings.
There is also an atmospherically vented area that can be pressurized with a sealing gas (special version).
The VSI is driven by a standard NEMA three-phase motor.
