NASH 904 Classic Liquid Ring Vacuum Pump

The NASH 904 is a two-stage liquid ring vacuum pump designed for applications requiring deeper vacuum levels and stable performance in demanding industrial environments.

Positioned as a mid- to large-capacity solution, it provides reliable operation across processes where consistent vacuum is critical to system efficiency and output quality. Its two-stage configuration enhances vacuum capability compared to single-stage designs, making it well suited for applications operating at lower absolute pressures.

Process Controls Corporation - NASH 904 Liquid Ring Vacuum Pump

Engineered for integration into both new and existing systems, the 904 offers a flexible design that supports a wide range of installation configurations. The liquid ring operating principle enables the pump to handle saturated gases, vapors, and process carryover without internal damage, maintaining performance in wet or contaminated conditions. This non-contact compression process also minimizes wear, supporting longer service intervals and dependable operation over time.

Built for continuous-duty operation, the NASH 904 maintains stable vacuum levels even under variable process conditions. It performs effectively in applications where temperature fluctuations, moisture, or entrained solids are present, helping reduce operational disruptions. Its ability to function in both vacuum and compression roles adds versatility for facilities managing multiple process requirements.
