Abstract

A striper can apply a polymer-based marking material comprised of a mixture of a material solution and a catalyst. The material solution and catalyst are mixed according to a desired ratio. A first pump drives the material solution and a second pump is slaved to the first pump and drives the catalyst. The second pump includes dual check valves within its piston, thereby ensuring that the second pump drives fluid during both its upstroke and its downstroke to maintain the desired ratio.
