Plan 41

Description: Product recirculation from discharge through cyclone separator and heat exchanger to seal chamber


  • Improves vapor point margin
  • Reduces seal operating temperature, can reduce coking or polymerizing and improve lubricity
  • Removes entrained solids from process fluid
  • Particles removed by cyclone separator are returned to pump suction

For use:

  • In hot services containing suspended solids




  • Throat bushing is recommended
  • For fluids with solids having a specific gravity twice or more than that of the fluid Cooler will require regular de-scaling in the water side
