HSR Diffusion pumps

Oil diffusions pumps have many applications in high-vacuum technology, for example in metallising systems, metallurgical facilities, vacuum ovens, laboratory pumping stations and many more.


The tried and tested diffusion pump technology of the former Balzers AG has been developed further after this business area was taken over by HSR AG.


In keeping with our standards, our customers can also expect the highest stability from these products.
