The Scientific Systems, Inc. (SSI) 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. The pumps are designed for a wide range of preparative and semi-preparative chromatography, SMBC (simulated moving bed chromatography), and many process and industrial applications.
Features include an integrated prime-purge valve, outlet filter, drip tray, leak sensor, pulse dampener, pressure monitoring, interactive keypad control and complete PC control and status monitoring through RS-232 and Micro USB 2.0 ports. Easy maintenance is built-in, with automatic piston wash and easy access to check valves, pistons, and seals, leading to greatly reduced down-time and operating expenses. Standard fluid path materials are stainless steel and PEEK, with optional titanium.
Jacketed heads are also available for temperature-controlled processes. With 100 mL/min and 300 mL/min versions, reaching pressures up to 4,000 psi, the PR Class pumps will meet the most demanding liquid chromatography and process requirements. All SSI pumps include a 3-year warranty. Internal components, including mechanisms and fluid path components, are also available in Kit Form for OEM Applications.
