EDP80

EDP pumps are based on Edwards’ oil-free, non-contacting, award-winning, reverse claw mechanism. They provide consistent vacuum at high efficiencies and low costs of ownership. Dry pumps completely eliminate all problems of process contamination and creation of polluted effluent, which are experienced with traditional wet vacuum pump technologies.

Features & Benefits

  • Staged compression for optimum temperature profile within the pump and no requirement for cooling gas injection
  • Inherently free draining
  • Able to handle liquid or particulate carryover
  • Short gas path eliminates particulate build-up and corrosion - Edwards’ patented design
  • Can flush with solvents, water or steam


Applications

  • Drying
  • Distillation
  • Reactor service
  • Solvent recovery
  • House/Central vacuum
