Edwards pioneering expertise is incorporated in our chemical dry pumps to satisfy the demanding requirements of the chemical, petrochemical and pharmaceutical industries. We offer a range of four pumps with 80 - 400 m³/h capacity, and ultimate vacuums of less than 1 mbar. Our chemical dry pumps meet the highest safety and performance standards.
EDP pumps are based on Edwards’ oil-free, noncontacting, 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 the creation of polluted effluent, which are experienced with traditional wet vacuum pump technologies.
STAGED COMPRESSION
Staged compression for an optimal temperature profile inside the pump, without the need to inject cooling gas.
SIMPLE AND ROBUST
Simple and robust construction with sufficient power to ensure reliable operation. Minimum design life of 25 years.
SAFETY
Pumps flammable gases safely. Pumps corrosive gases without corroding.
RELIABILE
Short gas path that eliminates the build-up of particles and corrosion - design patented by Edwards. Non-contact mechanism that provides long life and high reliability.
CLEANABLE
Can be cleaned with solvents, liquids or vapour.
ECONOMIC
Easy maintenance and low utilities consumption.
