Edwards has long been a pioneer of vapour pumps and diffusion pump technology with innovations such as the diffusion pump cold cap and the combined diffusion pump, the Diffstak. Edwards’s range of high throughput diffusion pumps have many advantages in industrial applications. The pumps, in back to back testing, are comparable to the best leading competition but also incorporating the above benefits. To offer even higher pumping speeds, of up to 45000 m3h-1 at pressures intermediate between mechanical boosters and diffusion pumps Edwards can supply our industrially proven vapour booster pumps.

A constant program of updates and improvements, with input from OEM’s and end users, ensures that the vapour boosters always meet the requirements of the industry. This combined with inherent reliability, ease of use, ease of maintenance and tolerance to a wide range of inlet and exhaust pressures means they have been used extensively in metallurgy and coating industries as well as many other specialist applications.Our industrial, high throughput diffusion pumps and vapour booster pumps fulfil the requirements of applications like vacuum metallurgy, distillation and coating. Our compact scientific pumps are designed for instrument and general R&D applications.
