All in One – Eliminates connection cable between pump and control unit – No rack mount controller, controller built in – super small foot print High Performance – Highest pumping speed in turbo-molecular class – 40% lmproved throughput – 32% Reduced power consumption in high gas flow
The STP iXA2206C Maglev turbo-molecular pump utilizes a magnetic bearing and motor drive system and has an ultimate pressure of 10-9 Torr. This integrated controller series can be fully interfaced with advanced controllers to operate on a wide range of applications and processes. It eliminates the need for a conventional, rack-mounted controller and interconnecting cables. The fully integrated product offers easy installation and small footprint as an all-in-one solution for all application tools. The rotor is entirely suspended by magnetic bearings so all contact between the rotor and the remainder of the pump is eliminated. As well as giving very low vibration, the elimination of contact means no bearing wear and no requirement for consequent pump maintenance. The STP iXA2206C can be connected directly to a terminal using a serial port and the STP-link Monitoring Software.

CORROSION RESISTANT: This pump has nickel coated rotors and stators and pump internals are suitable for corrosive gas applications. This ensures a high level of resistance to corrosion.
MAGNETIC BEARING TECHNOLOGY: The rotor is suspended by multi-axis magnetic bearings, so all contact between the rotor and the remainder of the pump is eliminated. As well as giving very low vibration, the elimination of contact means no bearing wear and no requirement for maintenance.
VIBRATION FREE: Magnetic levitation of the rotor results in an extremely low level of noise and vibration. Peakto- peak vibration level is less than 0.02 μm. This amplitude remains constant throughout the life of the pump and is free from troublesome subharmonics.
OIL FREE: All STP turbomolecular pumps are oil free. The use of magnetic bearings eliminates all hydrocarbon lubricants ensuring no contamination of the vacuum process from the turbomolecular pump. This feature is vital in industry and in surface science or high energy physics applications (where even minute degrees of contamination disrupt measurements).
MAINTENANCE FREE: Unlike conventional mechanical bearings, magnetic levitation means there is no frictional contact, eliminating sources of wear and vibration. This feature enables STP turbomolecular pumps to run for years with virtually no maintenance, reducing annual operating costs to a minimum and ensuring maximum up-time is achieved. This maintenance free feature can be particularly beneficial on processes producing chemical or radioactive contamination.
AUTOMATIC BALANCING SYSTEM (ABS): ABS is a unique patented development of 5-axis technology. If any rotor imbalance is introduced (by deposition of process by-products, for example), sensors in the pump detect changes in the rotor motion and compensate the magnetic bearing fields to allow the rotor to spin on its natural inertial axis. This minimises the vibration transmitted to the inlet flange. ABS works at all pump rotational speeds.
SAFETY BACKUP BEARINGS: STP pumps have dry lubricated axial and radial mechanical bearings as safety backup bearings. These support the rotor and protect the pump in the event of a total disruption of magnetic suspension or a massive air inrush which overcomes the magnetic bearing stiffness. These high precision ball bearings are dry lubricated and are not in contact with the rotor during normal operation..
