160 to 250 m³/h

Plus larger capacities if combined with Roots Boosters

Atm. to <0.02 mbar

Increased productivity and product quality

Robust

Reliable operation even in harsh industrial applications

<64 dB(A)

Quiet running with low power and utilities consumption

Intelligent

On-board controller with extensive communication and automated control capabilities

Advanced tapered-screw technology for exceptional performance and energy efficiency

From Acetates to Xylene (and everything in between), the Edwards CXS Chemical Dry Pump can help you to enhance performance with cutting edge intelligence and compression technology developed across thousands of chemical vacuum systems installed worldwide.

Innovative screw technology for optimized pumping

The CXS tapered-screw technology brings you improved thermal stability and optimised pumping at all inlet pressures. An added benefit is a corrosion-free operation and robust liquid and solids handling for your harsher chemical processes.

ATEX Certification/Explosion Proof Certified

The CXS is ATEX certified, with constructional safety and containment for pumping gases from groups IIB/IIB3. Explosion tested and certified by independent authorities, this is a pump you can rely on in even the most challenging environments.

Unprecedented control of your pump

You can monitor your pump’s data via its on-board communication controller for instant process improvements. The pump includes special start-up and shutdown modes to free the rotors or avoid cold seizures, if required.
