    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 pump assembly for serial connection along a primary fluid line includes a pump and a pump bypass. The pump has an inlet side and an outlet side, and is configured to receive a first fluid from the inlet side, and expel the first fluid from the outlet side. The pump bypass is actuatable between first and second valve states. The first valve state fluidly connects the pump in series along the primary fluid line, and connects an input side of the primary fluid line to an output side of the primary fluid line only via the pump. The second valve state fluidly isolates the pump from the primary fluid line, and fluidly connects the input and output sides of the primary fluid line via a continuously piggable path.
