Edwards Seiko Seiki STP-A803C Turbomolecular Vacuum Pump - REBUILT

Edwards STP-A803C turbomolecular pump is designed for use in semiconductor applications. Edwards advanced rotor technology gives class-leading performance for maximum process flexibility. The STP-A803C has been approved for use by major equipment manufacturers in the semiconductor and magnetic media industries.

Advanced Rotor Technology

  • Maximized process flexibility
  • Oil free
  • Low vibration
  • High reliability
  • Maintenance free
  • Harsh process compatible
  • Increased life

Advanced Controller Design

  • Auto tuning
  • Self diagnostic functions
  • DC motor drive
  • Battery-free operation

Compact Design

  • Small footprint
  • Half rack controller

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.
