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.
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.
