Parallel Pumping Controller with Load Sharing and Systems Including the Same

A method for controlling operation of multiple pumps in a parallel pumping application, the method comprising:

• controlling operation of a first pump via a first controller communicating with a first engine operable for driving the first pump;
• and
• controlling operation of a second pump via the first controller communicating with a second controller, which responsively controls operation of a second engine operable for driving the second pump according to controller-to-controller communications from the first controller to the second controller without a centralized programmable logic controller (PLC).

A non-transitory computer-readable storage media including executable instructions, that when executed by at least one processor, cause a first controller to:

• control operation of a first pump via a first engine operable for driving the first pump;
• and
• control operation of a second pump via communications with a second controller, which responsively controls operation of a second engine operable for driving the second pump according to controller-to-controller communications from the first controller to the second controller without a centralized programmable logic controller (PLC).
