Determining the type of pump

There are two types of pumps available; a piston pump and a diaphragm pump. Firstly, let us look at the piston pumps. When a piston sprayer is switched on, the piston will spin vertically up and down in a cylindrical casing to create pressure. This type of sprayer can usually muster up to 90 PSI of pressure, which is very high. The high pressured spraying means that they can be used for long distances as well. It also produces very fine water droplets/mists that cover the area completely. Another reason why a piston pump will be the best weed sprayer for large areas is that you can use it on high trees and large bushes. A lot of homeowners use these as they are easy to operate, understand and repair.
