Which Vacuum Pump Fits Which Chemical Process?

The efficiency champion takes the price! Dry compressing screw vacuum pumps with a particularly high degree of efficiency in the chemical production are challenging liquid ring pumps. At first sight, it seems clear which principle leads the way. However, this may be delusional.

In many cases, vacuum per se is an energy-saving measure. Many chemical reactions are accelerated by vacuum which allows the reduction of distillation temperatures required for the thermal separation of substances. Vacuum, however, costs energy and depending on the technology employed, this can come quite costly. Furthermore, it provides safety, e.g. if process vessels are evacuated, preventing dangerous reactions with oxygen, which can lead to an explosion.

However, vacuum pumps can also become a safety problem, if they are not designed properly or suitable for the application. In order to be always on the safe and efficient side, high competence is required, and this is in the most diverse fields of application.
