The NASH Certified Field Service team is available to supplement your in-house maintenance operations and keep your liquid ring vacuum and compressed gas systems running efficiently and reliably. Factory trained and located worldwide NASH Certified Field Service will help you identify needed repairs, prevent costly downtime, and increase mean time between failures. 

Field Services Include:

Fiberscope Inspections

One of the easiest ways to keep an eye on your liquid ring pumps & compressors is through a Fiberscope Inspection (also called borescope or videoscope). . Fiberscope inspections allow us to track the wear and condition of your pump’s internals without having to dismantle the unit. Our trained technician or field service engineer uses a small camera to visually inspect pump internals without disassembly. Inspections can be performed on-site, during a scheduled shutdown, and identify potential issues early before pump performance drops or failure occurs. The information gathered during a fiberscope inspection allow to:

  • Accurately plan the maintenance of your pump maintenance
  • Schedule and anticipate any repairs before the breakdown occurs
  • Save time & money by reducing the risk of unplanned downtime
