Oil Vapour Diffusion Pumps

The Edwards Diffstak vapour diffusion pumps are compact, water-cooled pumps with integral cooled baffles which provide exceptionally clean pumping. The proven design ensures very low backstreaming, reduced outgassing and minimized sealing requirements. These pumps are offered with integral manual or pneumatic high vacuum valves.

Edwards nHT series diffusion pumps provide stable high throughput vacuum performance. Designed for optimum energy efficiency, flexibility and low maintenance, the nHT series is the ideal solution for a variety of demanding industrial applications.

Edwards vapour booster pumps are designed to provide high pumping speeds at pressures intermediate between mechanical boosters and diffusion pumps. Continually improved and updated, the vapour booster pumps offer inherent reliability, ease of use, ease of maintenance and tolerance to a wide range of inlet and exhaust pressures making them ideally suited to industrial applications.
