HF 300 Pump

The HF Series Pumps are designed for Preparative Chromatography and LC Column Packing.

High Performance at a Low Cost

The HF Series Pumps are specifically designed to meet the requirements of Preparative Liquid Chromatography (HPLC) and high pressure process/metering applications. Standard features include LCD keypad and RS-232 interface.

Easy Maintenance

All SSI pumps are known for fast, easy maintenance. Check valves, pistons and seals are readily accessible, and Automatic Piston Wash is available.

Wide, Accurate Flow & Pressure Range

The HF Series Pumps are dual-head, positive displacement (piston) pumps with servo motors, belt drives and reliable eccentric cams. The unit delivers very precise flow rates up to 300 mL/min., with pressures up to 10,000 psi constant pressure and 8,500 psi for constant flow.

The Best Performance for the Investment

Available in all Stainless Steel or Titanium fluid paths, the HF Series Pumps provide high performance at a very competitive price. Prime-Purge Valve, Outlet Filter and Pressure Transducer are standard.
