Distillation with Vacuum

Where is vacuum used in distillation processes?
Vacuum distillation is an important process in the pharmaceutical and chemical industry and has applications in many other sectors including beverage and food production. Another example is crude oil refining: crude oil contains heavier and lighter hydrocarbons with different boiling points, requiring two distillation processes. After atmospheric distillation, a second distillation is carried out under vacuum to separate heavy hydrocarbons at lower temperatures, minimizing thermal cracking and the creation of unwanted by-products.

Our wide range of vapour-compatible, corrosion-free vacuum equipment is ideal for use in distillation processes. We offer ATEX (explosion-proof) models for use with flammable vapours, gases and liquids.

Which Busch product series are particularly suited to distillation processes with vacuum?
COBRA screw vacuum pumps are ideal for distillation applications as they generate high vacuum in a single stage. As these pumps operate without working fluids, they are able to extract media as a vapour without contamination. As a result, the media can be reused after condensation. An extensive range of sizes and models is available, including explosion-proof versions (ATEX).

Dolphin liquid ring vacuum pumps are extremely robust vacuum generators that are used in a number of distillation processes. They can be supplied in a wide range of series, sizes and material options to suit specific applications.


Huckepack rotary vane vacuum pumps have been used in distillation processes for more than 50 years. These two-stage vacuum pumps have a simple but proven design and are fresh-oil lubricated. The operating fluid is supplied to the compression chambers in minimal quantities. Process-compatible fluids can be used.

Oil-lubricated R5 rotary vane vacuum pumps are also suitable for use in distillation processes.
