Chemical and Pharmaceutical

Robuschi offers rotary lobe blowers, screw compressors, vacuum and centrifugal pumps for several chemical and pharmeceutical processes, such as cooling, distillation, degassing, drying, gas compression, pneumatic conveying, solvent recovery, thin layer evaporation and liquid handling.

Chemical pharmaceutical

Applications


Coating

When industrial surfaces are coated, metal vapours are handled under vacuum. In typical processes the metal condenses as a thin layer on the surface of the substrate. Vacuum is necessary to keep the metal vapours under pressure.

Rotary Lobe Blowers

Cooling

Surfaces are cooled through the controlled evaporation of water or other solvents. The latent heat of the substrate and the vacuum remove the localised heat, causing a cooling effect.

Vacuum Pumps

Distillation

Wastewater that is contaminated with solvents must be treated for environmental reasons. The simplest method is vacuum distilling, where the low-boiling-point fraction is evaporated and then condensed. The wastewater is then transported elsewhere for further use.

Vacuum Pumps Centrifugal Pumps

Degassing

Extruders are typically used for product degassing. In extruders highly viscous substances are compressed and simultaneously freed of solvents. The vacuum pump used serves exclusively to evacuate low boiling point solvents as well as any air that has entered the material through leaks.

Vacuum Pumps

Drying

All medical products are dried before entering the marketplace. Solvents are removed from the product in heatable static or dynamic dryers. The advantage of vacuum drying is that the product can be processed at low temperatures. The temperature always corresponds to the vapour pressure of the solvent being used.

Vacuum Pumps

Gas compression

Gases must be compressed before they can be pumped through pipelines for further use. In many cases this compression is also necessary in order to reduce the volume of storage space required.

Rotary Lobe Blowers

Impregnation

Impregnation involves the following process: the final product is evacuated in a receiving vessel. A suitable impregnating agent, such as a resin, penetrates the surface of the material under vacuum.

Vacuum Pumps

Pneumatic conveying

Chemicals can be conveyed safely and economically with stand-alone compressors or blowers. Dust free and therefore loss-free conveying, simple design of the piping and no deformation of the conveyed material are assured.


Solvent recovery

Wastewater that is contaminated with solvents must be treated for environmental reasons. The simplest method is vacuum distilling, where the low-boiling-point fraction is evaporated and then condensed. The wastewater is then transported elsewhere for further use.


Thin layer evaporation

This process, which is also called molecular evaporation, is used to separate substances that have narrow boiling point ranges. Such equipment has a special design that only operates properly at specific vacuum levels.

Rotary Lobe Blowers

Clean liquid handling

A very wide range of clean fluids can be handled in chemical and pharmaceutical sectors by means of centrifugal pumps.

Centrifugal Pumps

Process liquid handling

Centrifugal pumps are used to transfer different types of process liquids in chemical plants.
