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.

Product Features
