HS-2 Diffusion Pump

The Agilent HS-2 oil diffusion pump is a pump with high throughput and high pumping speed of 160 L/s air, 200 L/s He, H2. With its fully optimized vapor jet and the robust boiler design, the pump will run without any maintenance for many years. It is available with an ASA inlet flange and with 120 V or 240 V.

This pump is a perfect fit for instrumentation applications such as Gas Chromatography Mass Spectrometry (GCMS) and centrifuges.

  • High pumping performance in a compact package
  • Fractionating jet purifies pumping fluid
  • High tolerable forepressure
  • Stainless steel jet and pump body
  • Standard quick-cool fluid
  • Finned boiler increases surface area, prolonging pumping fluid life
  • Foreline baffle prevents pumping fluid loss into backing system
  • Pumping speed: 160 L/s, maximum throughput: 0.60 Torr L/s
  • Operating range: 3.7 x 10-3 to 5 x 10-8 Torr
  • 15 minute warmup time and 10 minute cooldown time
