Liquid Ring Vacuum Pumps

Liquid Ring Vacuum Pump

VacuStar WR Series

The Fruitland WR series pump is a versatile liquid ring pump which boasts very high CFM and safe operation when pumping flammable, corrosive, or toxic liquids and vapors. Liquid ring technology means that the rotor and vanes are surrounded and sealed by water or glycol and don’t contact the housing chamber – which makes the compression performance nearly isothermal.

All of this comes in a plasma nitrate coated aluminum construction, which means that this is a lightweight workhorse of a pump with low power requirements that can be used in any dirty or dangerous setting.

Features

  • Designed for low noise and low vibration
  • Capable of nearly isothermal compression of gasses (ATEX – temp. class 5)
  • Plasma nitrate coated aluminum construction with very high corrosion resistance
  • Low power requirements with high performance levels
