A classic side channel vacuum pump with innovative technology
With two hundred years of combined experience, two brands became one. In 2002, nash_elmo was established when Nash Engineering merged with Elmo Vacuum Technology. Both of these liquid ring vacuum pump technologies joined together became the world's largest manufacturer of liquid ring pumps and compressors. Gardner Denver acquired nash_elmo in 2004 and created the Gardner Denver Nash Division.
Our reliable G-BH1 side channel vacuum pump is reliable and delivers 20,000 operating hours between services and is virtually maintenance free. Frequency converters are used to control machine output and speed, which is advantageous in applications with variable operating loads. Machines that work with variable speed drive features improve suction and high differential pressures.
Decades of Proven Reliability
Some technologies are so good that it is hard to improve them. Regenerative blowers from Elmo Rietschle are such an example. They have proven their reliability in service for many decades, performing flawlessly day in and day out with virtually no down time. Noise levels are lower than that of most other vacuum pumps and compressors.
Our regenerative blowers are available in a wide selection for performance ranges up to 1,766 cfm at 60 Hz and differential pressures of up to 420 in. H₂O. With flexibility and power, these blowers cover a variety of demanding applications.
Our side Channel Vacuum Pumps reduce energy consumption, improve reliability and uptime, eliminate pollution and provide cost savings solutions for a wide variety of applications.
