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.
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.
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.
A range of Edwards’ pre-engineered modules can help you to meet your specific application needs. One single design includes options for multiple applications available as stand-alone pumps or complete systems, including mechanical boosters for your higher pumping capacities.
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.
CXS pumps are kinder on the wider-environment and your immediate working area, with no contaminated oil to dispose of and quiet running operations with low vibration.
