Supercritical CO2 Pumps

Please contact Barber-Nichols regarding Supercritical CO₂ Pumps for your electronic component cleaning, textile cleaning, or textile processing system. Helping organizations develop innovative solutions for the future is our specialty.

Barber-Nichols has also helped customers with the use of Supercritical CO₂ in an alternative textile dyeing process. Currently dye is dissolved in water and then applied to textiles. The process renders large quantities of water that must be cleaned before it can be reused or released from a factory. Should dye be dissolved in Supercritical CO₂ rather than in water, the cleanup process is simplified. The Supercritical CO₂ is depressurized at the end of the process, the dye drops out of solution, and the gaseous CO₂ and dye are easily separated.

Barber-Nichols recently designed and manufactured Supercritical CO₂ Pumps for two dry cleaning system manufacturers. The most common dry cleaning fluid in the United States today is a hazardous substance called Perchloroethylene (PERC). These two new environmentally friendly systems use Supercritical CO₂ , rather than PERC, and require BNI's circulation pumps for operation. The pumps are sealless and hermetic to prevent carbon dioxide from escaping the high pressure system, and utilize the system's Supercritical CO₂ to lubricate and cool the pump's bearings. BNI's work with low lubricity toluene lubricated bearings in the 1980s and water lubricated bearings in the 1990s uniquely positioned the company for these projects.

Barber-Nichols, Inc. (BNI) designs and manufactures custom Supercritical Carbon Dioxide (CO₂ ) Pumps. Supercritical CO₂ is an excellent solvent, and therefore extremely effective for the cleaning of electronic components and textiles. Because Supercritical CO₂ systems often operate at 56 bar (800 psi) or higher, BNI's sealless, hermetic pumps are an excellent choice for this application.
