Featuring an innovative double-ended screw mechanism, our CDX pumps have a pumping capacity of 900 m3h-1 (per hour) – perfect for your larger processes where repeatability and reliability are key.
When you work in critical applications, you need a reliable pump. The CDX pump is a robust high-performance machine that is highly tolerant to process malfunctions, delivering continuous performance you can rely on, from atmosphere to ultimate vacuum.
Edwards’ standard indirect cooling ensures exceptional temperature control, including protection from thermal shock and corrosion. The pump has excellent liquid handling capabilities and is dust and particulate tolerant, making it a first choice for numerous chemical, pharmaceutical and petrochemical applications.
A range of Edwards’ low-cost pre-engineered modules can help you to meet your specific application needs. Our customised systems include tailored applications support to help you maximise performance in a wide range of process conditions.
The CDX is designed to minimise your scheduled downtimes, from line maintenance to overhaul. On-site maintenance and cleaning options include bearing and seal change and cleaning of flame arrestors, with minimal process line disturbance.
Cooled, filtered oil for the bearings and rotor stub shafts avoids carburization and degradation, allowing you to save on costs by increasing mean times between maintenance and extending the overall life of the pump.
