EDP Chemical Dry

Dry Pumps

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.

80 to 400 m³/h

Plus larger capacities if combined with Roots Boosters

Atm. to < 0.5 mbar

Increased productivity and product quality

Industry tested

Specifically designed for chemical applications

Designed 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

Designed for safety and reliability

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.

Ideal pump for chemical application industries

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 long life performance and stability

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.

Unique award-winning construction

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.
