The SFT-10 is a robust, high precision carbon dioxide pump designed to deliver liquid carbon dioxide at pressures up to 10,000 psi (68.9 MPa). It may be used to deliver both liquid and supercritical CO2 to new and existing SFE equipment, including SFT’s model 100 SFE. It provides the capability to perform supercritical fluid reaction chemistry (SFR) when used to deliver carbon dioxide to one of SFT’s HPR Series™ high pressure chemical reactors. 
 
The SFT-10 incorporates a high performance, dual piston pump which rapidly produces the pressures required for supercritical fluid and other high pressure applications. Software safeguards protect from accidental over pressurization. The pressure set point is controlled from a push button display located on the control module’s front panel. 
 
The SFT-10 utilizes dual aluminum pump heads, Furon seals and sapphire pistons. The cam-driven pump mechanism employs a single stepper motor drive, dual ball and seat check valves (ruby ball, sapphire seat). The SFT-10 has a stainless steel fluid path, prime-purge valve, and a pressure transducer in a “T” fitting. The pump’s constant pressure mode features a selectable pressure set point. The flow rate automatically adjusts to maintain a set pressure. An optional “constant flow” mode is available. 
 
Pump head temperature is controlled by an integrated thermoelectric cooling module with finned heat sinks, pre-cooler and a fan. Cooling jackets and baths are not required. A quick-release mechanism allows easy access to pump heads for routine maintenance.
