Gardner Denver Nash extends its expertise in the market for liquid ring pumps with high volume flow rates with the new NASH 2BE4 model. The NASH 2BE4 was adapted logically to suit the process industry’s diverse requirements. Ten sizes, as well as two material types, make it into an adaptable pump for high gas volume flow rates.

The NASH 2BE4 was developed from the proven NASH 2BE3, whose reliable performance was further improved. The development focused on optimizing the performance data, especially in vacuum below 500 mbar abs, and on increasing the pump’s service life.
This was achieved by modifying the shaft bearings and optimizing the port plates and the impeller. Improvements to internal flow channeling have reduced the energy requirements by 6 to 8% while the scavenge performance remains constant.
