Efficient, reliable, and compact vacuum technology for demanding processes
NASH small capacity liquid ring vacuum pumps combine proven operating principles with modern engineering to deliver high performance, long service life, and minimal maintenance. The series includes models 2BV5, 2BV6, 2BV7, 2BM1, and 2BM5, covering a capacity range from 25 to 1,400 m³/h. These pumps are ideal for general industrial applications where reliable, quiet operation and flexible installation are essential.
Compact design and flexible installation
The series includes both monoblock and frame-mounted designs, providing space-saving installation and reducing the need for external couplings, bases, and guards. Units are supplied with motors that meet international standards and are suitable for 50/60 Hz operation.
Durable construction and corrosion resistance
All models are engineered for reliability and long service life. Materials include cast iron, bronze, or stainless steel (316) for excellent resistance to corrosive and erosive media. The magnetically driven 2BM series is hermetically sealed with no shaft seal, completely eliminating leakage risk, making it ideal for handling toxic, hazardous, or explosive gases and high-purity applications.
Low noise and vibration
NASH small capacity pumps are designed for quiet and smooth operation, with sound levels typically below 75 dBA, making them suitable for environments where noise control is important.
Reliable performance and long operating life
With simple internal construction, optional mechanical or magnetic sealing, and self-flushing internal design, these pumps can operate for up to 20,000 hours without maintenance. The liquid ring principle ensures stable vacuum performance, even when handling wet or contaminated gases.
Typical applications
The series is suitable for a wide range of industries, including chemical processing, food and beverage production, plastics manufacturing, pharmaceutical processes, and general industrial applications where reliable pump performance is required.
