Overview:
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
  • No internal valves to block or corrode and no interstage condensers to create potential for corrosion
  • Simple robust construction with ample power ensures reliable operation even during process upsets
  • Non-contacting mechanisms gives long life and high reliability
  • Pump flammable gases safely
  • Pump corrosive gases without corroding
  • Designed for long life and easy maintenance - Minimum of 25 years life expectancy
  • Lower cost of ownership
