Meets the Most Demanding Applications

The patented low dead volume pulse dampener and rapid refill in the 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 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 Series III is a direct replacement for many pumps, including Waters, Shimadzu, and other leading brands.

Performance and Reliability Beyond its Price

The use of digital stepper motor technology and the proven singlepiston 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 fewer number of parts required. It's so reliable it carries a three-year warranty. ​
