A robust, ergonomic and lightweight automatic Cooper Pegler knapsack sprayer. With a pressure limiter to help adjust to the pressure you need. Thanks to the CP15 Classic’s unique diaphragm pump system combined with the pressure control valve; this Cooper Pegler is the ideal knapsack solution for your crop protection needs. The fantastic diaphragm pump system of this knapsack sprayer creates a high amount of pressure through the deformation of a highly flexible diaphragm, the limited friction action of this flexible piece avoids the premature wear to the pump which can usually be caused by dirty water. The CP 15 CLassic sprayer comes with a yellow hollow cone nozzle and a green anvil nozzle.
