Types of Pumps
There are two types of pumps: piston and diaphragm
A piston pump typically provides greater pressure (roughly 90 psi). A piston pump works in an up and down motion and is contained in a chamber inside the tank. When you “pump” the lever, it creates pressure which forces the liquid down into the wand so that you can spray.
Piston sprayers cannot be used for abrasive chemicals as the chemicals will destroy the piston.
A diaphragm pump does not have the internal cylinder. The pumping of the handle moves the diaphragm to create the pressure. Diaphragm pumps are designed to use herbicides like Round-Up. This style of pump with invented to be able to handle abrasive chemicals and chemical residue.
