Infinity Supercritical announces a method to clean your Supercritical CO2 Fluid Extraction pump internal moving parts and seals using ethanol, without pump head removal.
Infinity Supercritical has developed a device which connects to your liquid CO2 pump, that will clean both your pump internal moving parts, and the seals, at the same time. Ethanol is pumped (using your liquid pump) closed-loop through the pump which dissolves any botanical oil build up.
The reclaimed oil from the pump can then be recovered using a rotovap. This pump cleaning device can be used with any Cat CO2 pump. Depending on the configuration of your liquid pump, the device may also be able to be used with other industrial CO2 pumps.
The main advantage of this type of closed-loop cleaning system is that you can clean the seals in place, without removing the pump head.
