SFT-10 High Pressure Carbon Dioxide Pump

SFT-10 High Pressure Carbon Dioxide Pump

SFT-10 High Pressure Carbon Dioxide Pump

Supercritical Fluid Technologies, Inc. introduces the completely self-contained SFT-10 Liquid Carbon Dioxide Pump, and advanced Peltier (thermoelectric) technology that can achieve high pressure without the need for an external cooling bath.

The pump can deliver carbon dioxide at pressures up to 10,000 psi (69 MPa) at flow rates from 0.01 to 24.0 ml/min.  These characteristics make the SFT-10 an ideal pump for use in supercritical fluid extraction, and a variety of other high pressure applications, including supercritical fluid reaction chemistry and chromatography.

The SFT-10 utilizes reliable, dual sapphire syringe pump technology to achieve high pressures rapidly. The Peltier chiller has superior cooling capability.  It maintains the temperature at the pump heads low enough to ensure the carbon dioxide remains liquid.

The standard operating mode is “constant pressure” where the pump will maintain a pressure set point.  An optional constant flow mode, from 0.01 to 24.0 ml/min., is available. 

The SFT-10 may be acquired as a stand alone CO2 pump or used as part of Supercritical Fluid Technologies’ SFT-110 / SFT-110XW Supercritical Fluid Extractors.

    TPU Pump Heads

    The TPU Pumps Heads by Aalborg Instruments are mounted on a front panel with an adjustable occlusion wall and safety cover. Installation is quick and easy by simply attaching the pump head to the motor using the existing mounting holes. The heads are designed for low to high viscosities and fluids never touch the pump head.

    Features for the pump heads include 4 rollers (TPU 1) or 10 rollers (TPU 2) to minimize pulsing, stainless steel rollers and shafts, mountable in any directions, and long tubing life. The maximum lift is 340 in. H2O (12.3 psig) and maximum suction is 350 in. H2O (12.6 psig). The pump head, the tubing’s inside diameter, and the motor’s RPM affect the flow rate.

      FlexSwitch FLT93 Pump Protection Flow Switch

      The FlexSwitch FLT93 Pump Protection Flow Switch reduces pump repair and extends pumplife by detecting dry running conditions caused by irregular liquid flows or slurries. It monitors the flow and temperature of liquids, gases, slurries, syrups, lubricants, coolants and more.  It is ideal for pump wet/dry detection, where sudden, unexpected reductions in media flow rates may leave pumps vulnerable to over-heating conditions that can result in bearing or seal damage that require major repairs or shorten their useful life. It also offers a highly robust scheme for pump protection with its dual alarm capability and  features a wide set-point range, which varies according to service media (liquid, gas or foam), beginning from 0.01 to 3 SFPS (0.003 to 0.9 SMPS) in water-based liquids.

        TUFF Air Sampling Pumps

        Casella CEL offers its TUFF line of personal air sampling pumps that feature a sealed case with over-molding that protects it from damaging moisture, extreme temperatures, solvents, and impact. Pumps possess a flow range from 5 ml/min to 4.5 l/min, and incorporate a double-acting diaphragm mechanism with digital control. Pump operation is guided by an intuitive user interface displaying real-time flow, sampled volume with run duration, a simple battery "fuel gauge" and alarm for flow or battery fault conditions. Typical run times of more than 30 hours (depending on media and flow rate) and meet applicable NIOSH and EN requirements.
