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.

The Series II is a direct replacement for many pumps, including Waters, Shimadzu, and other leading brands.

Performance and Reliability Beyond its Price

The digital stepper motor technology and the proven single-piston design perform like 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.

The Series II pump consists of a series of modular sub-assemblies packaged to meet basic metering and chromatography 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.
