Abstract

An automatic cleaning system is provided for a mud separator apparatus. Water and mud inputs to a mud pump feeding the separator are respectively controlled by two butterfly valves ganged for cooperation, and operated by a single valve actuator motor. When the mud separator is shut off, a time delay relay is actuated which keeps the mud separator rotor motor on line during a predetermined flush cycle. The valve actuator opens the water valve, and closes the mud valve, permitting the separator to be flushed with water. Activating the start button returns the valve actuator to the position in which the mud valve is open and the water valve is closed, thereby returning the apparatus to the mud separation cycle.
