Edwards Seiko Seiki STP-H451C Turbomolecular Vacuum Pump - REBUILT
An STP pump can be installed in any orientation and operate by remote control. If any rotor imbalance occurs (by deposition of process by-products, for example) sensors detect changes in its motion and compensate the magnetic fields accordingly. There are backup precision mechanical bearings to protect the pump in the event of a total disruption of magnetic suspension or a sudden massive air inrush that overcomes the magnetic bearing stiffness.
