CDX1000
Edwards CDX1000 represents the next generation of dry pump technology. The CDX1000 is a double ended mechanism for the chemical process, pharmaceutical and petrochemical industries.
 
This innovative technology leverages Edwards latest manufacturing and design philosophies. The CDX1000 is suited to larger processes where repeatability and reliability are key. Technologies and manufacturing techniques have been carefully selected to produce a robust, high performance machine that is simple to operate and maintain.
Performance with Reliability
- Outstanding temperature control with Edwards standard indirect cooling
        Process repeatability
        Protects pump from thermal shock and corrosion
- Excellent liquid handling
        No compression plate = no hydraulic lock
        Self draining mechanism
- Dust and particulate tolerant
        No expansion volumes
        No cold seizures
- Extended maintenance period
Cooled and filtered oil system
- No complex controls
Direct on-line start
Simple, Rugged Design
A robust mechanism for reliable, repeatable performance
- Double-ended, variable pitch screw
- Patented stator machining removes the need for a head plate
- No compression plate
- Minimal parts count
- Standard motors
- No coatings
- Low rotational speed
Maintainability
The CDX1000 is designed to minimize scheduled down-time from line maintenance to overhaul. 
- Minimized process line disturbance
        Integral flame arrestors can be cleaned and inspected without breaking process lines
        Silencers are drainable and cleanable
- Standard automotive style oil filters
- Bearing and seal change is possible on-site
- Recovery philosophy minimizes pump removal
Clearances open up on cooling; no cold seizures
- Rotors do not require costly re-coating
- Rotors are not assembled as matched pair
Cool & Clean
The  bearings and rotor stub shafts are fed cooled, filtered oil. Limiting  the oil temperature prevents carburization and degradation. 
- Extended bearing and seal life
