Agilent large diffusion pumps provide high throughput with pumping speeds of 8,000–50,000 L/s with low backstreaming.

VHS-400 Diffusion Pump

The VHS-400 Diffusion Pump has a pumping speed of up to 4500 L/s. All VHS series pumps have sight glass/fill and drain assemblies for continuous monitoring and easy maintenance of pump fluid. The patented Bulge Contour increases gas capture and maintains lower pressure. Finned boilers increase surface area, prolonging pumping fluid life.

This Vapor Jet Pump is great for high vacuum applications. This pump is a perfect fit for industrial applications such as vacuum furnace, heat treatment, metallizing, and coating processes for architectural glass and the automotive industry.

HS-16 Diffusion Pump

The Agilent HS-16 Oil Diffusion Pump is a pump with high throughput and high pumping speed of 6000 L/s. With its fully optimized vapor jet, the robust boiler design and the thermal protection switches the pump will run without any maintenance for many years. It is available with 16 in. ASA or ISO 500K 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.

HS-20 Diffusion Pump

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.

HS-32 Diffusion Pump

The Agilent HS-32 Oil Diffusion Pump is a pump with high throughput and high pumping speed of 32,000 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 32 in. ASA or ISO 800F (bolted) 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.

NHS-35 Diffusion Pump

The Agilent NHS-35 Oil Diffusion Pump is a pump with high throughput and high pumping speed of 50,000 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 35 in. ASA or ISO 1000F (bolted) 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.
