The Edwards vapour booster pumps offer higher pumping speeds, of up to 15000 l/s at pressures intermediate between mechanical boosters and diffusion pumps. Vapour boosters from Edwards have been proven in the field for over 30 years. With a constant program of updates and modernisation, with input from OEM’s and end users, combined with inherent reliability, ease of use and tolerance to various inlet and exhaust pressures they have been used extensively in metallurgy and coating industries as well as other specialist applications.

Product Features

LARGE PUMPING SPEED

very large pumping speed at high operating pressures.

HIGH CRITICAL BACKING PRESSURES

allow the use of relatively small mechanical backing pumps.

Edwards vapour Booster

HIGH THROUGHPUT

very high throughput at operating pressures.

BEST USE

the pumps are used in the 10⁻¹ to 10⁻⁴ mbar range where rotary pumps are at their limit and ordinary diffusion pumps exhibit instability.

FOR CONTAMINATED SYSTEMS

most useful in pumping contaminated systems and high loads of hydrogen, hence their use in metallurgical and chemical processes.
