High-flow Dual Head Pumps
What is the ReaXus® PR Class?
The ReaXus® PR Class consists of rugged, dual-headed positive displacement piston pumps designed to deliver high, accurate flow rates together with strong pressure capability for a wide range of applications.
The pumps are intended for preparative and semi-preparative chromatography, as well as SMBC (simulated moving bed chromatography), and are also suitable for many process and industrial applications.
Performance and operating rangeÂ
The PR Class is available in two flow rate versions:
- 100 mL/min
- 300 mL/min
Both versions reach pressures up to 4,000 psi, supporting demanding LC and process requirements.
Fluid path materialsÂ
Standard fluid path materials include stainless steel and PEEK, with optional Hastelloy available. Jacketed pump heads are also available for temperature-controlled applications.
Control and connectivityÂ
The PR Class includes integrated control and monitoring features:
- Integrated Prime-Purge Valve
- Interactive keypad control
- RS-232 and Micro USB connectivity
- Ethernet communication
- Run/Stop and analog control (0–10 V, 4–20 mA)
- Full PC control and status monitoring
