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. This expertise is incorporated in our chemical dry pumps to satisfy the demanding requirements of the chemical, petrochemical and pharmaceutical industries. EDP Chemical Dry Pump can get peak pumping speed from 83 m3h-1 to 427 m3h-1 and ultimate vacuum from 0,5 mbar to 0,2 mbar.
