SFT-SeriesIII

SFT – Series III Digital Pump

The SFT-Series III pump consists of a series of modular subassemblies packaged to meet any isocratic application requirements. The extensive use of digital logic and a micro-stepped motor allow for precise and flexible control. The user interface consists of an LED display and keypad. The self-flush head and a three-year warranty ensure years of trouble-free service. Method development is easy with Autoprime™ purging. Upper and lower pressure limits can be easily set, and the pressure can be monitored on the LED display. External control gives flexible performance at an affordable price.

When combined with a SFT-Series II or III pump, keypad controller, detector, and injector, you have an economical, flexible binary gradient system.

Meets the most demanding applications
The patented low dead volume pulse damper and rapid refill in the SFT-Series III make this single piston pump virtually pulse-free. It meets the requirements of the most demanding detectors.

Analytical and semi-prep separations
Flow rates from .001-5 ml/min, 0.01-10 ml/min, and 0.1-40 ml/min are available.

Material compatibility for all applications
The SFT-Series III is available in either traditional 316 stainless steel or biocompatible PEEK™ (polyetherether ketone) for metal-sensitive applications.

Reduced maintenance
Seal life is dramatically extended by actively flushing the back of the primary seal with a flushing solution. The result is less down-time and reduced operating expenses. The self-flush is automatic; just change the flushing fluid weekly. Seals can be changed in five minutes without tools.

Easy solvent changes
Autoprime™ one-button purging makes it easy to prime or purge the pump.

Works in your existing system
The SFT-Series III is a direct replacement for many pumps, including Waters, Shimadzu, and other leading brands.

Performance beyond its price and the security of a 1-year warranty
The use of digital stepper motor technology and the proven single-piston design gives the performance of the most expensive pumps at a fraction of their cost. The operating cost is lower too, due to the simplicity of the design and fewernumber of parts required. It’s so reliable it carries a 1-year warranty.

Intended Applications

  • Isocratic applications and metering
  • Biocompatible applications
  • Semi-preparative to 40 ml/min.
  • Quality assurance
  • Education
