Graco SoloTech Hose Design

With only the hose in contact with the fluid being pump and no check valves in line, Graco’s SoloTech peristaltic pumps are ideal for materials that other pumps cannot handle. Abrasive, corrosive, shear sensitive, and gas entrapped fluids can easily be pumped or dosed into your application.
