Overview
A Liquid Ring Vacuum Pump is a rotary positive displacement device utilizing an impeller rotating eccentrically within a liquid-sealed casing. Constructed primarily from stainless steel or cast iron with elastomeric seals, it operates on ISO standards for vacuum systems to generate stable suction without internal lubrication.
Application
- Chemical Processing: Solvent recovery and distillation under inert atmospheres.
- Petrochemical: Crude oil degassing and pipeline evacuation.
- Food & Beverage: Deaeration of liquids and sterile packaging lines.
- Pharmaceutical: Filtration assistance and freeze-drying cycles.
Precautions
- Maintain strict temperature control to prevent liquid vaporization.
- Inspect mechanical seals quarterly for wear to avoid leakage.
- Replace working fluid filters annually to ensure system efficiency.
