Two Stage Liquid Ring Vacuum Pump (TS Series)

The pump operates by forming a liquid ring using sealing liquid inside an eccentrically mounted impeller. Gas is drawn in, compressed across two stages, and discharged smoothly. The second stage enables deeper vacuum and improved efficiency while safely handling wet and vapor-rich process gases.

Two stage pumps provide lower achievable vacuum levels, better stability at higher vacuum ranges, and improved energy efficiency under demanding conditions. They are better suited for critical processes where single-stage pumps struggle to maintain performance or experience efficiency drop-offs.

Yes. JOYAM’s two stage liquid ring vacuum pumps are specifically designed to handle high moisture content, saturated vapors, and condensable gases without performance degradation. The liquid ring acts as a natural sealant and coolant, ensuring stable operation in challenging process environments.

These pumps are widely used in chemical processing, pharmaceuticals, food and sugar industries, distillation plants, extrusion lines, and sterilization systems. Any application requiring deep vacuum, vapor handling, and continuous operation benefits from a two stage liquid ring design.

At deeper vacuum levels, two stage pumps operate more efficiently than single-stage systems. Their optimized compression reduces energy losses, allowing stable vacuum generation with controlled power consumption, especially in continuous-duty industrial processes.

Selection depends on required vacuum level, gas composition, vapor load, operating pressure, and duty cycle. JOYAM works closely with customers to evaluate process conditions and recommend or engineer a solution that ensures performance, reliability, and long-term operational efficiency.

The pump operates by rotating an impeller inside a cylindrical casing partially filled with liquid. Centrifugal force forms a liquid ring, creating compression chambers that draw in gas, compress it, and discharge it smoothly, ensuring stable vacuum performance even in humid or vapor-rich conditions.

The LR Series is ideal for dehydration, filtration, evaporation, concentration, distillation, degassing, venting, process exhaust, and industrial drying applications where consistent vacuum and reliable handling of moisture and vapors are essential.

Single stage pumps are designed for moderate vacuum levels with simpler construction, making them well-suited for general industrial applications. Two stage pumps achieve deeper vacuum levels and are typically used where lower absolute pressures and higher efficiency are required.
