Abstract
A liquid pumping system adaptable for connection to either an electrical drive motor or an internal combustion engine, wherein a generator and clutch is coupled to the driving source, and a pressure sensing switch is connected to the generator rotor to selectively provide voltage to a rectifier circuit and field winding for the clutch. The energization of the field winding causes the clutch to actuate and thereby causes a mechanical coupling to a reciprocable pump for developing liquid pressure.
