Our systems provide a variety of eco-friendly and reliable solutions that optimize production in degassing vacuum applications. Do you want to find the vacuum technology that will help you optimize your process? Then click the cards below to explore our product offering.
Degassing is an important chemical and pharmaceutical application. A vacuum is required for removing dissolved or trapped gasses from liquids and solutions in preparation for further processing such as distillation, deodorization and extrusion. Degassing helps to prevent cross contamination, improves product physical characteristics, reduce or prevent corrosion, shortens processing cycles and reduce capital cost for low pressure processes.
It is a process carried out on liquids to:
NASH systems are the premier choice for degassing vacuum applications in drug production. Our safe and reliable pumps help eliminate gas bubbles that can interfere with heat transfer and cause corrosion. Equipped with cool running liquid ring technology, they can handle moist and explosive gas streams.

NASH dry systems deliver dry, clean, flexible, and safe vacuum solutions. They are engineered for rigorous, non-stop demands of the harsh industrial environments of the pharmaceutical and fine chemicals industries. Our dry vacuum pumps & systems are some of the most reliable and efficient solutions on the market.
The dry and contact-free operation requires no lubrication in the pumping chamber. This allows dry pumps to operate at high temperatures. Without condensation inside a dry pump, there is no corrosion, polymerization or contamination.
Dry operation eliminates the risk of the process gas reacting with any liquids or lubricants. It also ensures that corrosion does not occur inside the process chamber.
• No contamination of process streams
• Deep vacuum, (to 10-3 mbarA with mechanical boosters), and flexible operation
• Capacities not limited by cooling water temperatures
• No effluent or pollution generation
• Pump explosive gases safely with ATEX-certified systems
• Immediate solvent recovery at the pump exhaust
• Easy service
• Lower total cost of ownership from lower utility, service & maintenance costs
