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.
