Stop wasting energy using hand-pump spraying equipment! Designed for professionals who demand the greatest possible control during applications of insecticides, herbicides and fungicides, this battery-powered unit allows you to spray for up to seven hours or roughly 200 gallons on a single charge. The diaphragm pump with viton seals delivers constant pressure and homogeneous drop size for reliable, consistent performance. Electronic pump pressure regulation allows for three application speeds: low pressure (suitable for herbicide treatments), intermediate pulsation (suitable for herbicide and insecticide treatments) and high-pressure spray (recommended for insecticide treatments and medium-high crops).
