The GRACO 19C645 SoloTech ST6 Pump is a peristaltic hose pump designed for metering or transferring caustic, abrasive, or sensitive materials. It features a single roller that compresses an engineered hose through a full 360 degrees of rotation, ensuring only the hose contacts the fluid. The pump is constructed for reliability and ease of maintenance, with no valves, seals, or glands required. It is intended for use in demanding industrial applications where chemical compatibility and minimal maintenance are critical.
