The multi-axis magnetic bearing system is used to suspend the rotor during operation, ensuring there is no risk of contamination while minimising vibration, noise and maintenance requirements.

The STP pumps can be fully interfaced with advanced controllers to operate on a wide range of applications and processes. They offer class leading pumping performance demonstrating exceptional levels of reliability, and are widely accepted in the market with the installed base of over 140,000 units worldwide.They are the preferred choice for many of the most challenging semiconductor applications. For laboratory applications this makes STP maglev turbomolecular pumps extremely reliable.

Product Features

CORROSION RESISTANCE

most models of Edwards STP maglev turbomolecular pumps are also available in a special corrosion resistant version with nickel coated rotors and a nitrogen purge facility, making them ideal for chemical laboratory applications.

OIL FREE

ensures clean vacuum, low power and low vibration. the use of magnetic bearings eliminates all hydrocarbon lubricants.

VIBRATION FREE

magnetic levitation means no friction and thus extremely low vibration, in addition this remains constant and does not change as parts wear.

AUTOMATIC BALANCING SYSTEM

Edwards 5-axis pumps are able adjust the magnetic field dynamically to take out rotor imbalances.

MAINTENANCE FREE

zero friction means no wear and thus no routine maintenance is required in normal operation.
