ReaXus PR ClassReaXus PR Class

High-Flow Dual Head Pumps

The rugged PR Class consists of dual-headed positive displacement piston pumps that provide high accurate flows and excellent pressure capability for a variety of uses. Standard fluid path materials are Stainless Steel and in addition to optional Hastelloy.

The pumps are designed for a wide range of Preparative and Semi-Prep Chromatography as well as SMBC (simulated moving bed chromatography) and many process and industrial applications. With 100 mL/min and 300 mL/min versions reaching pressures up to 4,000 psi the pumps will meet the most demanding LC and process needs.
