Vacuum pumps & compressors

Efficient and reliable vacuum and compression solutions for industrial processes
We offer a complete range of NASH liquid ring vacuum pumps across small, medium, and large capacities. Combining proven liquid ring technology with modern engineering, these pumps deliver high performance, long service life, and minimal maintenance. Models include small capacities (2BV5, 2BV6, 2BV7, 2BM1, 2BM5), medium capacities (SC, 2BE1, Vectra GL, Vectra XL), and large capacities (2BE4, CL, 905, P2620), covering a flow range from 25 to 39,000 m³/h.

Flexible design and installation
NASH pumps are available as monoblock or frame-mounted units, ensuring compact and straightforward installation. Many models offer 2-in-1 operation as both vacuum pump and compressor, reducing the need for separate equipment and simplifying plant layout. Magnetically driven models are hermetically sealed with no shaft seal, eliminating leakage and making them suitable for handling toxic, explosive, or high-purity gases.

Durable, low-maintenance operation
All models are engineered for long service life and reliability. Small and medium pumps feature simple, well-proven components with self-flushing designs, while large pumps have only one moving part (rotor) to minimize wear and maintenance. Variable conical porting and optimized rotor geometry ensure stable and efficient operation under demanding conditions, including wet or contaminated gases.
