The NASH 905 liquid ring vacuum pump series has been optimized to deliver superior reliability and performance over the existing 904 and CL models. With capacities ranging from 4,800 to 22,000 m3/h (2,800 to 13,000 ACFM) the 905 is ideal for applications such as chemical processing, paper, mining, geothermal power generation or anywhere reliable compression of corrosive gases is needed.
• Demanding environments
• 2in1: pump & compressor
• Reliable and efficient
The 905 liquid ring vacuum pump and compressor series is an upgrade to the proven 904 model and has been engineered to deliver improved performance and reliability.
The 905 provides lower life-cycle costs with an improved variable port design, enabling a wider operating range with improved efficiency, water-saving technology, and simpler seal line piping. It also includes a patented gas scavenging feature to provide superior performance and longevity at high vacuum levels.
The 905 series has been engineered for reliable operation and performance in harsh applications such as chemical processing, paper, mining, geothermal power generation, or anywhere reliable compression of corrosive gases is needed. Constructed of 316L stainless steel the 905 offers excellent corrosion resistance and can be outfitted with a variety of mechanical seals.
Some applications require vacuum and compression in one process. Instead of handling the gas with two separate machines, our liquid ring vacuum pump and compressor models can do the job with only one pump - reducing cost and simplifying installation.
Patented in 1932, Nash’s variable conical porting design allows the force of compression to counter the weight of the rotor and shaft to help minimize load on bearings during operation. The variable porting optimizes pump performance across the entire operating range. With constant innovation, Nash’s patented design features:
