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.
Application-specific modules
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.
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.
Friendly to the environment
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.
