Method and apparatus for controlling a pump

DETAILED DESCRIPTION In carrying out principles of the present invention in accordance with a preferred embodiment thereof, the pump is started only when the valve is in a first position and is run in a steady state operation only when the valve is in another position.
The valve is operated only when pressure of fluid provided to the valve from the pump is above a selected level.
A timed start circuit is provided to allow such pressure to build up during pump start.
More specifically, according to a feature of the invention, a valve actuated limit switch controls a pump initiating circuit and a timer establishes a start interval for a timed start circuit.
Sensed pressure, at an acceptable level, operates to maintain the valve in a steady state run condition so that a limit switch on the valve will hold the pump in a steady state run condition.
