Description The CP3 diaphragm pump sprayer is a tough and accurate sprayer. Due to its simple design, it also had an ecomomic advantage for the buyer. The CP3 diaphragm pump tolerates abrasive particles, like wettable powders and dirty water and there are no direct friction surfaces so it is also easy to pump. A relief valve limits the pressure to approx. 1 bar, recommended for herbicides, and approx 3 bar, recommended for fungicides and insecticides. The excess liquid simply returns to the tank. No service maintenance or lubrication is required other than routine cleaning. The valves are corrosion resistant and the diaphragm is mineral resistant. The CP3 is simple to use. The tank is not pressurised and spraying is controlled from the trigger valve. A lightweight yet very strong lance minimizes fatigue on the user wrist.
