a70544000 - EDP160 50Hz, Bareshaft Pump

EDP160 50Hz, Bareshaft Pump

A70544000

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.
