Agilent Varian HS-20 Diffusion High Vacuum Pump - NEW

The Agilent HS-20 Oil Diffusion Pump is a pump with a high throughput and high pumping speed of 10,000 l/s. With its fully optimized vapor jet, robust boiler design and thermal protection switches, the pump will run without any maintenance for many years. It is available with 20 in. ASA or ISO 630K inlet flange.

This pump is a perfect fit for industrial applications such as vacuum furnace, heat treatment, metallizing, and coating processes for optical lenses, electronics, and protective film layers.

  • Five-stage fractionating jet purifies pumping fluid and assures low base pressure
  • High tolerable forepressure
  • Full thermal protection
  • Fluid-level sight glass provides quick indication of pump fluid status at all times
  • Fill and drain assembly for pump oil
  • Standard gauge port (NW-25) below inlet flange included
  • Foreline baffle prevents loss of fluid into backing pump system
  • Optional halo baffle reduces backstreaming without adding height
