EDP200 Drystar®, 460V, 60Hz Standard

A70552908

Overview

Edwards is a market leader in dry pump technology and pioneer of dry vacuum for the chemical process, pharmaceutical and fine chemical industries. The EDP200 utilizes the proven reverse claw mechanism, proven over more than 10 years and 80000 installations worldwide, to provide a clean and robust vacuum solution
The proven and rugged non contacting design includes the ability to control pump body or stator and internal gas temperatures allowing a comprehensive range of solvents, flammables and corrosives to be pumped and systemized variants to address the EU’s explosive atmosphere (ATEX) directive for Category (Zone 0) T4 operation.

Technology

Dry running pumps have no oil, steam or water in the process volume. This eliminates, at source, the pollution traditionally associated with wet sealed vacuum systems and provides cost and materials handling benefits as the sealing medium does not have to be replenished:
 
  • NO contamination of the process stream
  • NO polluted effluent
  • NO messy oil drums
  • Improved processing with reduced down time
  • Low utility and consumable costs

Edwards EDP range are designed specifically for all chemical environments and by customizing the system can be used from the lightest to the harshest duty.
 
  • Vertical orientation
    • allows condensates to drain
    • can handle liquid slugs
  • A torque limiting clutch (can be reset) protects against hydraulic lock
  • Indirect cooling circuit allows variable and controllable case temperatures
  • Shortest gas paths prevent local condensation and particulate build up
  • Suitable for indoor or outdoor installations

 

Applications

  • Distillation
  • Drying
  • Evaporation/Crystallization
  • Solvent Recovery
  • Reactor Service
  • House Vacuum
  • Filter/Dryer
