CDX1000 Dry Vacuum Pump, 40 HP, 60 Hz, Flame Proof (without Integral Flame Arrestors)

A70812985

Overview

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.

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
