NEV series new liquid ring vacuum pump

The NASH ECO new liquid ring vacuum pump NEV series is a brand new upgrade on the 2BV series products. More suitable for extracting gases, water vapor, and media containing impurities. The suction pressure can reach 33mbar. A (97% vacuum degree). When the vacuum pump operates for a long time with a suction pressure below 80mbarA, a cavitation protection tube should be connected to protect the pump. If equipped with an atmospheric injector (see attached table), the suction pressure can reach 10mbarA. The injector can be directly installed on the vacuum pump.

The NEV series adopts a space saving coaxial design (with a protection level of IP55) and applies multiple technologies. The structure is simpler and the appearance is more exquisite. Better performance, easier installation and use, more stable operation, longer service life, and lower maintenance costs

NEV series new liquid ring vacuum pumpWidely used in industries such as medical, electronics, chemical, pharmaceutical, food, beverage, environmental protection, as well as various scenarios such as hydrocarbon cleaning, plastic extrusion, packaging machinery, etc.

performance curve

The performance curve is obtained under the following conditions: saturated air at 20 ℃, exhaust pressure of 1013mbaA, working fluid temperature of 15 ℃, and allowable performance error of ± 10%. After being equipped with an atmospheric injector, the suction pressure can be less than 33mbar.

Performance characteristics:

Compact design with fewer components and smaller size.

100% oil-free design.

• Special Lobe purge interface design

External open maintenance window.

Multiple materials are available for selection.

Multiple vacuum pump accessories are available, including cavitation protection valves, working fluid constant flow valves, and quick couplings for suction and exhaust ports.

User benefits

• Simpler structure and smaller footprint.

• More environmentally friendly, ensuring clean and oil-free process media

• Meet the self-cleaning requirements of the pump under operating conditions, making cleaning easier and extending the service life of the pump

The valve plate can be replaced without disassembling the pump, making maintenance more convenient.

Suitable for various harsh working conditions.

Make the installation and use of the pump simpler, and improve operational stability and reliability.
