EDP CHEMICAL DRY VACUUM PUMP Giving you a clear edge PRODUCT DATASHEET Edwards, a world leader in dry vacuum pump technology, successfully pioneered the use of environmentally friendly dry vacuum pumps in the early 1980s. With hundreds of thousands of systems installed worldwide, Edwards dry pumps create significant benefits for customers in many applications and industries. This 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 m3h-1 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. Features and benefits Industry proven, tried and tested Specifically designed for chemical applications Designed and tested for safety and reliability Stable operation, even during process upsets Low cost of ownership Easy maintenance, low utilities consumption and no cooling gas injection required
