With only the hose in contact with the fluid being pumped and no check valves in line, Graco's SoloTech peristaltic pumps are ideal for materials other pumps can't handle. Single Roller Design The single roller compresses an engineered hose through a full 360 degrees of rotation. This reduces compressions, temperature, and friction; improving hose life.
