The Importance Of Vacuum Degassing

Degassing is an important application in the pharmaceutical industry that requires vacuum technology for the removal of dissolved or trapped gases from liquids or solutions, such as water, or products. The process of degassing improves the product’s physical characteristics to allow further processing and avoid cross-contamination and corrosion.

During this process, gases, liquids, and other products are extracted under vacuum from the processed material; therefore, improving the quality of the products and shortening processing cycles.

NASH vacuum systems provide a variety of energy-efficient and reliable solutions that optimize production in degassing applications.

Solutions For Vacuum Degassing

Liquid Ring Vacuum Pumps & Compressors

Dry Screw Vacuum Pumps & Systems

Ejectors & Hybrid Vacuum Systems

Proven Performance For Vacuum Degassing

NASH vacuum systems are the premier choice for degassing applications in the pharmaceutical industry because they are safe and reliable. Liquid ring vacuum pumps & compressors are installed in harsh industries, such as pharmaceuticals to eliminate the formation of gas bubbles.

Gas bubbles can interfere with heat transfer during the process and cause corrosion, which is why it is necessary for them to be removed.


Moreover, NASH liquid ring technology can handle moisture-laden inlet streams and cool running liquid ring technology that is ideally suited to handle explosive gases. Additional liquid ring benefits include:

  • Process compatible seal liquid 
  • Low maintenance, high reliability 
  • Wear-free performance - no metal to metal contact 
  • Handles carryover and moisture-laden gas streams 
  • ATEX versions available 

Clean, Oil-Free Vacuum

NASH dry vacuum pumps & systems deliver dry, clean, flexible, and safe vacuum solutions that are engineered for rigorous, non-stop demands of tough industrial environments; such as pharmaceutical and fine chemicals. These dry vacuum pumps & systems are one of the most reliable and highly efficient solutions on the market.

The dry and contact-free operation requires no lubrication in the pumping chamber. This translates into major advantages like no process contamination and no pollution caused by the pump operation. Since these are oil-free, non-contacting screw designs, NASH dry pumps can safely and reliably handle corrosives, organics, inorganics, and solvent.
