CDX Chemical Pumps


CDX Chemical Pumps

Featuring an innovative double-ended screw mechanism, Edwards‘ CDX Chemical Pumps have a pumping capacity of 900 m3h-1 (per hour) – perfect for your larger processes where repeatability and reliability are key.


CDX Chemical Pumps overview

  • High throughput processes: 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.
  • Designed for harsh environments and processes: 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.
  • 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.
  • Easy to maintain: 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.
  • Saving you operating costs: 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.
