The sprayer can basically be divided into the following parts:
Gun, tip, Motor & Drive System, Pump Assembly, filter, Pressure Control, auxiliary spray accessories.
Gun
• Acts as the on/off valve for the material Spray Tip
• Controls the amount of fluid sprayed by using different orifice sizes
• Orifice shape determines the spray pattern.
• Many Graco tips can be turned to the reverse position by hand to blow out clogs
Motor & Drive System
• A heavy duty system that drives the pump
Pump
• Also called the Fluid Section
• Delivers a steady stream of high pressure fluid through the hose to the Spray Gun filter,
• Prevent large particles from entering and avoid clogging the Spray gun
Pressure Control
• Used to regulate the fluid pressure delivered from the pump
