A NASH liquid ring system does not require many of the complicated instrumentation safety and ancillary accessories that add complexity to hot-running pumps and compressors.

* more economical over its life cycle 
* last longer; highest reliability
 * requires significantly less maintenance than other vacuum pumps and compressors
 * provides more uptime for your plant
 * does not require many of the complicated instrumentation safety and ancillary accessories that add complexity to hot-running pumps and compressors
 * cool running, minimal temperature rise between inlet and discharge; pumps acts as condenser, allowing smaller, less costly equipment selection
 * only one moving part; simple and reliable operation
 * no metal-to-metal contact; constant wear-free performance
 * no internal lubrication required; less maintenance required; less downtime
