Abstract

A pump 24 with speed control is utilized. A dispenser 12 may have a trigger 14 which actuates a valve 16. Dispenser control 18 has “up” and “down” buttons, 20 and 22 respectively. The controls 28(comprising elements 18, 20 and 22) for the pump 24 are remote from pump 24. The controls communicate with the pump via wires or radio frequency (RF) 26 to regulate pump speed. Quick button (20 and 22) presses will incrementally change the flow setting while long button (20 and 22) presses will change the settings at a higher rate. This control method can also be tied to the controls located on the pump 24. The potentiometer 30 on the pump 24 will set a max setting, and any adjustments at the valve can go below this setting and back up to it, but never exceed it.
