Product Features

DOUBLE-ENDED SHAFT SUPPORT

Non-cantilever design provides secure rotor support for extremely low vibration and superior starting reliability, especially on harsh processes. Superior liquid and powder handling.

BEARING AND LUBRICATION

Oil lubricated gears eliminate grease and the need for periodic maintenance. Uses advanced quality bearings and special
purpose oil with low vapour pressure for
application compatibility and greatly
improved life.

ADVANCED SHAFT SEAL TECHNOLOGY

Non-contacting long-life seals with integral oil blocking labyrinth seal provides for highly effective sealing. Combined with a six litre per minute seal purge the gearbox is protected from contamination and the vacuum space is kept free of oil.

MOTOR AND DRIVE TECHNOLOGY

Extremely high efficiency motors with
electronic drives deliver maximum torque
performance for difficult Processes. Hermetically sealed motor eliminates oil leaks and improves pump reliability. Water-cooled motors and drives provide for improved reliability and long life to reduce service costs.

ROOTS BOOSTER MECHANISM

High efficiency vacuum booster design.  Optimised for maximum performance with automatic thermal management.

ADVANCED MECHANISM DESIGN

Enhanced screw-type rotor design results in smooth, gradual compression along the length of the rotor for improved thermal control and optimised pumping at all inlet pressures. Advanced machining techniques and design features eliminate the need for rotor coatings while maintaining superb ultimate vacuum
performance.
