  • Patent number: 10197047
    Abstract: A hydraulic proportioning system has a flow divider providing hydraulic fluid to drive two hydraulic pumps. The flow divider provides set amounts of hydraulic oil to each of two pumps, and the pumps each provide one material of the plural component material downstream to a mixing manifold. The two materials are mixed at the mixing manifold before application. The flow divider drives each pump at a set speed depending on the volume of hydraulic oil provided to each pump. The flow divider thus determines the ratio of the first material to the second material provided to the mixing manifold by the pumps.
