    Abstract: A method for a system having a plurality of primary fluid sources and a fluid output with a common pump includes halting pumping of a first fluid, isolating the common pump from the fluid output and the primary fluid sources, connecting an inlet of the common pump to a solvent source and a compressed air source, and an outlet of the common pump to a waste fluid dump, filling the common pump with a first purge volume of solvent, cycling the common pump in a flush mode, operating the common pump in a timed flow mode, and connecting an inlet of the common pump to a second primary fluid source, and an outlet of the common pump to the output line, and starting pumping of a second fluid from the second primary fluid source through the output line.

    Abstract: A two-component pumping system includes a first pump for pumping a first component, a second pump for pumping a second component, a motor, and a yoke assembly for connecting the motor to the first pump and the second pump and driving them simultaneously. The first pump includes a first displacement rod that reciprocates in a first pump axis. The second pump includes a second displacement rod that reciprocates in a second pump axis parallel to the first pump axis. The motor includes a drive shaft configured to reciprocate in a drive axis that is parallel to and in a common plane with the first and second pump axes. The motor is also configured to drive the first and second displacement rods in unison. The yoke assembly includes a top connector and a shoe. The top connector connects to the drive shaft.

    Abstract: A mix manifold (16) includes a plurality of valves to control the flow of material therethrough. First and second valves (36a, 36b) are linked for simultaneous actuation. The first and second valves each include valve members (56a, 56b) disposed within and rotatable relative to seal bodies (58a, 58b). The valve members seal against the seal bodies and the seal bodies seal against the manifold. A solvent valve (36c) also includes a valve member (56c) in a seal body (58c). The first and second valves are configured to open only when the solvent valve is closed. The solvent valve is configured to open only when the first and second valves are closed. The solvent valve can rotate between a plurality of positions to control the flow of solvent to flowpaths downstream of the first and second valves.
