Abstract
A plural component pump system is provided for delivering plural liquid components at a selected ratio. The pump system includes a first brushless DC motor configured to drive a first pump that pumps a first liquid component to an output and a second brushless DC motor configured to drive a second pump that pumps a second liquid component to the output. The pump system includes a first controller configured to control the first motor and a second controller configured to control the second motor. The pump system also includes a communication interface between the first controller and the second controller. The first controller is configured to send a signal to the second controller using the communication interface and the second controller is configured to control the second motor based on the signal to deliver the first and second liquid components to the output at the selected ratio.
