The Nash 2BE5 has been launched to build on the 2BE4 series. The development goal was to optimize and extend the performance the vacuum range below 300 mbar abs. The result: The new 2BE5 series pumps are able to achieve vacuum levels down to 100 mbar abs. This is made possible primarily by optimization of the gas flow. The patented gas scavenger provides increased vacuum capacity and, consequently, a significant improvement in terms of efficiency. Compared to the basic 2BE4 model, water consumption in the once-through mode has been reduced by up to 25%. Improved fluid self-recirculation eliminates the need for booster pumps.

Gardner Denver has restructured the activities within its Engineered Products Group: The CF (Multistage Centrifugal Blowers) organization of Gardner Denver, encompassing the Hoffman and Lamson brands, become part of the Gardner Denver Nash division.
The liquid ring vacuum pump is one of the workhorses in the chemical and petrochemical industry. The construction provides a nearly isothermal compression at comparatively low temperatures. Polymerisation and other undesirable reactions (thermal cracking, cakings) are largely avoided under these conditions. The ring consisting of liquid is used as tightening element desensitising the system against liquid hammers and drops in the gas flow handled, as they often are produced during extraction of inerts from condensers. The construction without touching and wearing parts makes our customers feel confident of reliable availability. A hermetically sealed design with magnetic coupling or canned motor does not only increase availability – since regular change of mechanical shaft seal is no more necessary – but also meets customers requirements in case of toxic gases and pumping liquids demanding “TA-Luft”.
The UK-based pump manufacturers and distributors, Tomlinson Hall, is embarking on a major export campaign for their unique range of Liquivac liquid ring vacuum pumps. With almost 1,000 Liquivac pumps already in use, the company have prioritised the establishment of a global distribution network as the first step in developing overseas sales. Colin Simpson, Business Development Director, said, “To be honest, we’ve never really pushed the pumps before as they have tended to sell themselves into various niche applications.”
