Edwards - Model CDX1000, 30kW, 50 Hz, -Flame Proof with Integral Flame Arrestors

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.

Technology

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 pairs

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
