The EDP chemical dry pump is a market-leading product ideally suited to the complex demands of your chemical, petrochemical and pharmaceutical applications. Innovative technology delivers performance and operational advantages in even the harshest process environments.
Specifically designed for your harsh chemical operations, the EDP is dynamically explosion-tested and certified by independent authorities. Further checks include leak checks up to 10-3 mbar l/s and type pressure tested from 22 - 75 barg – this is a pump you can rely on in even the harshest environments.
The EDP vacuum pump is temperature controlled for optimised operating conditions - hot for corrosive applications and cool for other gases. Edwards’ patented design for a short gas path eliminates particulate build-up and corrosion within the pump, giving you reliable performance, year after year.
Designed for a minimum of 25 years of operation with one year of unattended operation and three years between stripdowns, the EDP significantly reduces your overall cost of ownership.
When you specify an EDP pump, you benefit from Edwards’ oil-free, non-contacting, award-winning, reverse claw mechanism. The stator and rotors are constructed from non-brittle ductile iron materials to ensure long-life.
