Pfeiffer Vacuum+Fab Solutions Launches New Generation of Chemically Resistant Rotary Vane Vacuum Pumps

Date: April 16, 2026

Pfeiffer Vacuum+Fab Solutions, a member of the global Busch Group, has announced the launch of its new DuoVane C series — a next-generation line of chemically resistant rotary vane vacuum pumps engineered for demanding and corrosive industrial applications.

The introduction of the DuoVane 12 C and 22 C marks the company's latest advancement in delivering high-performance, durable vacuum solutions tailored for challenging process environments. The C version has been specifically developed for use in corrosion-intensive applications. Highly resistant PEEK vanes increase durability against the process media used in customer applications. In addition, the pumps are designed for operation with high-purity, inert PFPE oil. This combination reduces chemically induced aging processes and ensures particularly stable and reliable long-term operation.

A stainless steel gas ballast system enables reliable handling of condensable and aggressive process media. The innovative design reduces the risk of leakage, preventing both air ingress into the pump and the uncontrolled escape of process media. Furthermore, the DuoVane C features two different 1/8" threaded connections, allowing flexible installation of automatic valves in two mounting orientations and their seamless integration into the process.

The vacuum pump design ensures a stable pressure baseline — a key requirement, particularly in leak detection. An optimized high vacuum safety valve reliably prevents contamination due to short closing times during shutdown and in the event of a fault.

“The DuoVane C is a successor to the C versions of our former Pascal and DuoLine series. We consistently continue their proven strengths, now based on the new DuoVane platform. The vacuum pumps can be used globally, are reliable, and deliver high performance," explains Fabian Böcher, Product Manager for rotary vane vacuum pumps at Pfeiffer Vacuum+Fab Solutions.

The Busch Group is one of the world's largest manufacturers of vacuum pumps, vacuum systems, blowers, compressors, chambers and gas abatement systems, with more than 8,000 employees in 47 countries and annual consolidated revenue of €2 billion.
