Degassing With Vacuum Pumps & Systems

The Importance Of Vacuum Degassing

Degassing is a vital application in the pharmaceutical industry that requires vacuum technology for removing dissolved or trapped gases from liquids or solutions, such as water or products. The degassing process 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. Discover more by selecting our product cards below.

Vacuum Degassing Pump Solutions

Proven Performance

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. Therefore, the reason for their removal.

Moreover, NASH liquid ring technology can handle moisture-laden inlet streams and cool running liquid ring technology; 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 engineered for rigorous, non-stop demands of harsh industrial environments, including pharmaceutical and fine chemicals. Our 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 solvents.
