BBES: CO2 pump starving for CO2 - WKB10588

Article number: 10588

SYMPTOMS

  • High pump RPMs
  • Low CO2 density
  • Low pump pressure

ENVIRONMENT

  • SFE Bio-Botanical Extraction System
  • BBES
  • Chromscope
  • P-200

CAUSE

Blockage in the system upstream of the pump.

FIX or WORKAROUND

  1. Clean the filter.
  2. Find the blockage by breaking fittings.
  3. Flush with ethanol or replace, as appropriate.
  4. Increasing the system chiller temperature might help soften material in blockage, if it is in the chiller.

ADDITIONAL INFORMATION

Performing the cleaning as per Bio-Botanical Extraction Systems Guide (715004757) will flush out the lines prior to the CO2 pump.  Chapter 9.7 shows the details of a system using an automated recycler.  Chapter 9.8 shows the procedure with a manual recycler.
