Turbo-V 551 Navigator Turbo Pumps Agilent Technologies

The Turbo-V 551 Navigator turbomolecular vacuum pump with MacroTorr drag technology delivers high compression ratios, high throughput, and high discharge pressures for a wide-range of high vacuum applications.  The unique bearing and permanent dry lubrication in the V 551 eliminate oil and maintenance, and permit operation of the pump in any orientation.  Agilent (formerly Varian) offers the V 551 with Navigator on-board controllers with integrated electronics, or with standard rack controllers for simple installation.  The Turbo-V 551 is available for sale in system packages with controller, inlet screen, and power cables included, or as stand-alone pumps.  A version optimized for scanning electron microscopes produces minimal vibration and the lowest magnetic signature available.


  • MacroTorr drag technology allows higher foreline pressure, higher efficiency and smaller backing  pumps, in a compact, economical package
  • Pump ceramic bearings are permanently lubricated due to the extremely low vapor pressure of the solid lubricant
  • Pump can be mounted and operated in any position
  • No maintenance, no oil, no refill, and no contamination
  • Precise thermal design reduces heat dissipation and power consumption
  • Navigator on-board controllers provide plug-and-pump operation, or rack controller option matches your current system architecture
  • T-plus software option runs on your PC to allow remote operation and performance monitoring
  • SEM version use superior vibration isolation system to outperform mag-lev pumps, and has the lowest magnetic signature of any pump in its class
  • Typical Turbo Pump Applications
