Gardner Denver, founded in 1859, is a global provider of industrial equipment, technologies and related parts and services to a broad and diverse customer base through a family of brands. The company’s Nash brand is a leading supplier of liquid ring vacuum products and recently introduced its new NASH 2BE5 series of liquid ring pumps.

The new pump series is able to achieve vacuum levels down to 100 mbar abs and improved efficiency of up to 10%. Developed as an extension of the proven NASH 2BE4 series, the NASH 2BE5’s patented gas scavenger provides increased vacuum capacity and efficiency. The new model reduces water consumption by up to 25% when compared to the previous 2BE4 series. The pump’s improved fluid self-recirculation eliminates the need for booster pumps, translating to 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 m³/h, reaching down to 100 mbar abs of vacuum.

When used as a compressor, the NASH 2BE5 series achieves between 3000 and 9500 m³/h with compression of up to 2.5 bar abs.

The outer dimensions, footprint and port sizes of the NASH 2BE5 series are identical to the basic NASH 2BE4 model, facilitating a painless upgrade process for end users with an older model.

The NASH 2BE5 is available in ductile iron and stainless steel, or in a combination of the two materials. In ductile iron, the body is always supplied with a polyisoprene lining. The pump series is ideal for a wide range of applications in the chemical process, filtration, pulp and paper, power plant and refinery industries.
