ATEX certification
The Huckepack oil-lubricated rotary vacuum pumps are designed to comply with European directive 2014/34/EU (ATEX) and have been configured for safe use in hazardous areas to provide extra protection in explosive environment (Ex II 2(i)/2(o) G IIB(i)/IIB (o) T3(i) T4(o)).
 

Huckepack ATEX series

The Huckepack once-through oil lubricated rotary vacuum pump has proven its reliability and adaptability for years in the food processing, chemical, pharmaceutical and plastic industries, in metallurgy, waste water treatment, solvent recovery and many more aggressive applications:

Vacuum distillation
A mixture of fluids can be separated based on their boiling point differences through evaporation and condensation. Vacuum is used to speed up this process by reducing the required temperature to achieve the boiling point and increase the product selectivity. In distillation applications where acidic media or monomers are involved, the Huckepack is the ultimate solution which can handle such fluids without any damage to the vacuum pump unlike other technologies which will corrode quickly.

Monomer production
Styrene, an important industrial unsaturated aromatic monomer, forms the basis of synthetic rubber and highly heat-resistant plastics for phone housings, pipe fittings or automotive parts. It is usually produced at high temperatures under low pressure. Because this process generates a considerable amount of particles and solvent vapors, the Huckepack technology is the perfect solution for this application. It can of course also be used for the production of all other monomers.

Olive oil extraction
During the extraction of olive oil, the olives undergo a series of oxidative reactions which lead to a lower content of the main flavours and anti-oxidant properties of the plant. Working under pressure guarantees a better preservation of the olive fragrance and nutriment by reducing the presence of air and thus reducing the oxidation of the olives. The Huckepack is the most appropriate solution as the processes involves a lot of vapor. Moreover, the process oil can be used as the vacuum pump’s lubricant.

Fatty acids production
Fatty acids, basic substances for food, nutrition and cosmetics applications, are produced using water for the hydrolysis of fats and oils into a mixture of glycerin and fatty acids. This mixture undergoes vacuum distillation and fractionation in order to obtain purified fatty acids. Because the process involves a prolonged exposure of the fatty acids under high and unstable temperature, polymerization or syrup formation may occur, making the Huckepack the solution of choice in such applications.
