Edwards’ easy-to-use CXS pumps feature cutting edge tapered screw technology, have excellent reliability, are simple to install, environmentally friendly and give improved liquid and solids handling. As a result, they are economic to run and users can optimize their vacuum processes and minimize overall cost of ownership. CXS pumps enable users to minimize their environmental impact, according to the manufacturer. They provide all the advantages of dry pumps, with low energy usage and utility costs, deep and flexible vacuum down to 10-3 mbar, no contamination of the process stream or cooling water and no effluent generation. They are robust and reliable even in harsh pumping environments and have excellent liquid and solids handling capability, with the ability to pump up to one liter of liquid per minute continuously and up to 25 liter slugs without stopping. The pumps are independently certified for use in hazardous environments to ensure safe pumping of flammable gases. They also pump corrosive gases without corroding.
