NASH NEV series liquid ring vacuum pump is a new upgrade on the 2BV series, more suitable for extracting gas, water vapor and media containing impurities down to inlet pressures of 33 mbarA (97% vacuum). All these vacuum pumps are supplied with built-in cavitation protection. For long-term operation below 80 mbarA the cavitation protection should be connected for protecting the pump. An inlet pressure of 10 mbarA can be achieved by connecting a gas ejector (see accessories).  The gas ejector can be mounted directly onto the vacuum pump.

NEV series are space saving units in monoblock design (Protecting class IP55) of patented technologies for a simpler structure and more compact appearance with better performance, easier installation and use, more stable operation, longer service life, and lower maintenance costs.
