  • Ground striper pump piston having dual checks
    Patent number: 10669679
    Abstract: A pump for a striping machine includes dual check valves within its piston. At least one of the dual check valves is closed during an upstroke of the piston, thereby ensuring that the pump drives fluid during both its upstroke and its downstroke to maintain a desired ratio between a fluid output by the pump and a material solution output by another pump of the striping machine.

  • GROUND STRIPER PUMP PISTON HAVING DUAL CHECKS
    Publication number: 20190264401
    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.
