Design Features

High Efficiency

  • Lower power requirements
  • X-Ducer design can permit upgrades with minimal investment

Simplicity of Design

  • Proven reliability
  • Familiar to operating and maintenance personnel due to design – components and methods similar to conventional centrifugal pumps
  • When required, maintenance is easy to perform

Superior Reliability and Flexibility of External Vacuum Pump Degas System

  • X-Ducer design further simplifies the degas system for consistency ranges up to 10-11% by not requiring a vacuum pump
  • Easy to maintain external vacuum pump
  • Avoids assembly techniques needed to achieve close clearances for proper internal degas operation
  • Same back pull-out assembly regardless of type of degas system

Control Scheme

  • Simple level or flow control scheme when required
  • Readily adapted to variable speed operation
  • Effective response to  process changes and upsets

Continued New Technology and Development

  • X-Ducer design allows for operation up to 10-11% consistency without a vacuum pump
  • Higher TDH generation with X-Ducer design
  • New size now available for higher production rates and high head requirements such as O2Delignification Reactor Feed service
