Securing our future.<br />
S-VSI TWISTER and G-BH2 VELOCIS<br />
Technical market leadership is a fundamental<br />
aspect of our corporate philosophy –<br />
and we are once again proving this claim<br />
with the newly developed S-VSI TWISTER<br />
screw vacuum pump. In addition to considerable<br />
efficiency and a final vacuum<br />
of less than 0.1 mbar (abs.), the perfected<br />
screw profile provides maximum volume<br />
flow at high vacuum level.<br />

The non-contact operation screw rotors of the<br />
S-VSI TWISTER require no lubrication in the<br />
working area. This means that there are no<br />
costs for disposing of contaminated oil. The<br />
improved screw rotors have a variable lead<br />
progression and are gear-synchronized.<br />

Advantages of the new S-VSI TWISTER<br />
screw vacuum pump:<br />
• Short evacuation times<br />
• 0.1 mbar final vacuum<br />
• Low compression heat<br />
• High maximum tolerable water<br />
vapor inlet pressure<br />
• Low noise level<br />
• High suction capacity<br />
• Easy on maintenance<br />
• Highly effective<br />
• Variable number of revolutions possible<br />
• Less waste heat<br />
Robust, durable construction<br />
A long useful life and standard maintenance<br />
as well as compatibility with steam and fluid<br />
are important features of this construction<br />
concept. Noise and vibration levels are<br />
remarkably low.<br />
