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.

Zellstoff Pöls, in Austria, is one of the largest manufacturer of high quality, chlorine-free bleached long-fibre sulphate pulp in Central and South Eastern Europe. For the new PM2 paper machine, Nash is supplying the vacuum system for dewatering in the wire section and the press section. The Zellstoff Pöls PM2 focuses on “machine glazed” papers (a paper with very high strength), and incorporates the production of paper basis weights between 28 and 120 g/m². This wide product spectrum places high demands on the flexibility of the vacuum system, as the method of drying has to adapt to each paper grade. The major challenge was adapting the vacuum at the various suction points for each specified paper weight and the required drying needs. This was accomplished through the use of frequency converters that allowed for “fine adjustment” of the speed and the vacuum level to meet the specific requirements of the paper grade produced.
