Knapsack is a sprayer that sprays liquid through a hand-held nozzle connected to a pressure reservoir on the operator’s back. The knapsack sprayer can be used to dispense liquids such as fertilizers, herbicides, insecticides and fungicides.

LEVER OPERATED KNAPSACK SPRAYER
It is commonly known as knapsack sprayer. The sprayer is mounded on the back of operator with help of a pair of mounting straps. The pump of the sprayer is actuated by working a hand lever up and down by one hand of the operator and the other hand holds the cut off device for spraying purpose. This sprayer consists of liquid tank, hydraulic pump, operating lever, pressure chamber, agitator, delivery hose, spray lance and nozzle. A bean shaped plastic tank of 14-16 liters capacity is commonly used. It is necessary to operate the hand lever continuously at the rate of 15-20 strokes per minute. The normal working pressure is 40 psi.
