A vacuum level down to 100 mbar abs. and improved efficiency of up to 10%: with its new NASH 2BE5 series, Gardner Denver Nash is extending its competence in the market for liquid ring pumps with high gas flow rates.

2014-11-08 082713

The NASH 2BE5 has been launched to build on the proven NASH 2BE4 series, further improving its already impressive performance. The development goal was to optimize and extend the performance the vacuum range below 300 mbar abs. The result: The new NASH 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, which in turn creates greater energy savings.

Service aspects were also taken into consideration during the 2BE5 development: Removable bearing brackets simplify on-site maintenance and help to reduce repair times. Rigidity is improved by bolt connections of the body and side shield, producing an optimum seal in compressor operation. Certification to ATEX is already in the pipeline, making this pump also suitable for use in potentially explosive atmospheres.

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, they achieve between 3000 and 9500 m³/h 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 series has been consistently developed in line with the wide- ranging requirements of the process industry. Two material options and a wide range of material combinations have made this an adaptable pump capable of addressing a wide spectrum of applications. The NASH 2BE5 is available in ductile iron and stainless steel, or a combination of these two materials. In ductile iron, the body is always supplied with a polyisoprene lining. This allows the series to be used in wide-ranging types of applications across many sectors of industry, including chemical process engineering, filtration applications, the pulp and paper industry, in power plants, refineries and many others.

GDNash-pr-2be4-sGardner 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. Optimization of the shaft bearings has increased machine flexibility in the event of operational malfunctions and, in addition, has ensured better lubrication, which is positively reflected in the service life. An optional connection for flushing the housing is also available. This feature improves cleaning possibilities and, in the process, increases the service life.

The performance range of the NASH 2BE4 is unique within the market; it can be used as both vacuum pump and compressor. When used as a vacuum pump, volume flow rates of between 2,500 and 32,000 m³/h produce a vacuum of 160 mbar absolute; when used as compressor, 3,000 – 9,500 m³/h are possible and a compression pressure of up to 2.5 bar absolute can be achieved.

With regard to its external dimensions, the NASH 2BE4 model is identical to its predecessor the NASH 2BE3. As a consequence, exchanging or upgrading to a more efficient machine is possible without any problems.

The NASH 2BE4 model is available in nodular graphite iron and stainless steel. In this way, the model can be used for diverse applications in many industries: in chemical process technology, filter applications, the paper industry, power plant technology, refineries and in many more applications.

Reliability, efficiency and flexibility make the NASH 2BE4 an outstanding liquid ring pump for high volume flow rates.

NASH vacuum pumps for the PM 7 in Dunaujvaros

Gardner Denver Nash Germany supplied the complete vacuum system for dewatering in the forming and press sections of the new PM7 paper machine in Dunaujvaros. This technology has already proven itself in every other paper machine within the Hamburger Group, with robustness, efficiency and flexibility that guarantee the highest operational reliability.

On the new PM7 in Dunaujvaros, nine NASH 2BE3 vacuum pumps are used. Each pump is driven by a motor equipped with a frequency converter, allowing the rotational speed to be set to exactly suit the actual process conditions. This causes the vacuum pressure to adapt to process conditions as well. Additionally, three centrifugal fans for the low-vacuum scavenge points in the forming section have been included. As a result, the vacuum system provides the greatest flexibility at optimum efficiency.

For the plant operator, the advantages of a NASH liquid ring vacuum system were obvious:

  • An extremely robust system: overload safe and resistant to process failures
  • Very high overall efficiency, particularly in conjunction with optimum control
  • Optimum felt dewatering through the volumetric operating principle of the liquid ring vacuum pump - the scavenge pressure adjusts automatically to suit the felt permeability
  • Scavenge-side liquid carry-over with low fiber content is not a problem for the NASH pumps
  • Rotation speed control offers the potential of high energy savings
  • Low specific power requirements
  • Low noise emissions due to low peripheral speeds of the vacuum pump
  • Future system adaptation, without influencing other scavenge points, is easily done by changing the rotation speed of individual vacuum pumps
  • High operational safety, even if individual vacuum pumps are deactivated
  • Very low service and maintenance costs


Confidence in more than 100 years of know-how accumulated by the market leader in the paper industry
With the decision to use NASH vacuum pumps, the plant operator also made a decision for an innovative, environmentally friendly and economical attractive solution.
