Patent abstract
A fast fill pump system for a self-propelled field sprayer includes high capacity centrifugal pump for tank filling. The centrifugal pump is connected in parallel with the fill connection and primed by a lower capacity diaphragm spraying pump. Two check valves and a pressure sensor allow the sprayer control to automatically control the pump priming and tank filling with the activation of one switch. The two-pump system preserves tank filling speed, even during operation of eductor or tank agitation functions. The centrifugal pump can be removed and the spraying pump operated to fill the tank without substantial base machine modification.
