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.

More About EDP Chemical Dry Vacuum Pumps
EDP Chemical Dry Vacuum Pumps
EDP pumps are based on Edwards’ oil-free, non-contacting, award-winning, reverse claw mechanism. They provide consistent vacuum at high efficiencies and low costs of ownership. Dry pumps completely eliminate all problems of process contamination and creation of polluted effluent, which are experienced with traditional wet vacuum pump technologies.
EDP Chemical Dry Vacuum Pumps Overview
- Designed for safety and reliability: Specifically designed for your harsh chemical operations, the EDP is dynamically explosion-tested and certified by independent authorities. Further checks include leak checks up to 10-3 mbar l/s and type pressure tested from 22 – 75 barg – this is a pump you can rely on in even the harshest environments.
- Ideal pump for chemical application industries: The EDP vacuum pump is temperature controlled for optimised operating conditions – hot for corrosive applications and cool for other gases. Edwards’ design for a short gas path eliminates particulate build-up and corrosion within the pump, giving you reliable performance, year after year.
- Designed for long life performance and stability: The EDP chemical dry vacuum pump is designed for a minimum of 25 years of operation. With one year of unattended operation and three years between strip-downs, the EDP significantly reduces your overall cost of ownership.
- Unique award-winning construction: When you select the EDP chemical dry pump, you also select Edwards’ oil-free, non-contacting, award-winning, reverse claw mechanism. The stator and rotors are constructed from non-brittle ductile iron materials to ensure long-life.
- Custom systemization design and build service: Using pre-engineered modules together with an extensive CAD capability, we can custom design and build your system installation. This allows you to future-proof your installation for subsequent expansion or reconfiguration.
- Wide range of maintenance and service packages: To ensure that the vacuum pump maintains its performance over time, we offer a wide range of tailored service solutions for all applications.
