NASH introduces new liquid ring pump for improved gas efficiency

The new product optimises and achieves vacuum levels down to 100 mbar abs. According to the company, this is made possible primarily by optimisation 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 per cent.

Improved fluid self-recirculation eliminates the need for booster pumps, which in turn creates greater energy savings.
The NASH 2BE5 series can be used both as a vacuum pump and a compressor. For vacuum generation, suction capacities are between 2500 and 32000 cu/m per hour, reaching down to 100 mbar abs of vacuum.

NASH said that service aspects were also taken into consideration during the 2BE5 development. It now has removable bearing brackets simplify on-site maintenance that help to reduce repair times. Rigidity is improved by bolt connections of the body and side shield, producing an optimum seal in compressoroperation. Certification to ATEX is already in the pipeline, making this pump also suitable for use in potentially explosive atmospheres.

When used as a compressor, they achieve between 3000 and 9500 cu/m per hour with compression of up to 2.5 bar abs.

In terms of their outer dimensions, footprint and port sizes, the NASH 2BE5 series is identical to the basic NASH 2BE4 model, making it simple to upgrade to a new, more efficient machine at any time.

The NASH 2BE5 is available in ductile iron and stainless steel, or a combination of both.
