Overview

• 　　Why does the agricultural knapsack sprayer use a piston pump instead of a diaphragm pump?

  　　With the agricultural knapsack sprayer, the tank is never under any pressure, which is why it is safe to wear and use without the threat of a tank explosion. With this system, the pump generates pressure on demand in a separate chamber.

  　　The pump generates pressure and relies on a piston or diaphragm. The piston pushes air into the pressurized chamber in the same way that a bicycle pump pushes air into a tire. Diaphragm pumps, however, push air into the pressurized chamber in a similar way to a blacksmith's bellows.

  　　As the piston moves through the cylinder, it starts to create friction. If the spray fluid contains any particles, the friction causes the system to wear out quickly. Diaphragm pumps do not have any moving parts. Therefore, they do not generate any friction.

  　　This absence of friction reduces the wear and tear of the machine and extends its service life.
