Edwards Vacuum Liquid Rings

When your process involves high levels of contamination, liquid slugs, or condensable vapors, you need a vacuum solution that won't quit. Edwards Liquid Ring Vacuum Pumps are the industrial standard for "wet" applications, offering a robust, positive-displacement design that thrives where other technologies fail.

By using a rotating ring of liquid to create a hermetic seal, these pumps handle moisture and particulates with ease, making them the primary choice for Chemical Processing, Pulp & Paper, Power Generation, and Wastewater Treatment.

The Edwards range is tailored for the most demanding process industries, featuring both single and two-stage machines to ensure optimum efficiency across your entire vacuum range.

  • LR1A & LR1D Single-Stage Power: Massive capacities reaching up to 40,000 m3/h.
  • LR2D & SHR Two-Stage Precision: High-vacuum stability with capacities up to 7,500 m3/h (LR2D up to 50 HP. SHR greater than 50 HP)
