Parts of Graco Electric Airless Sprayer Pumps
Motor
The motor is the heart of the pump. It converts electrical energy into mechanical energy to power the pump’s movement.
Inlet Valve
This valve allows paint or coating material to enter the pump from its source through a suction hose. It also stops the material from flowing back into the source during operation.
Outlet Valve
Once pressurized, the paint or coating material exits the pump through the outlet valve.
Prime/Spray Valve
This valve controls the paint or coating material flow from the pump to the spray gun. It allows for a smooth transition between priming and spraying functions.
Piston Rod
The piston rod handles the up-and-down movement of the pump. This motion generates pressure to force paint or coating material.
Cylinder
The cylinder houses the piston rod and helps create a tight seal to stop leakage during operation.
Suction Hose
This hose links the pump to the paint or coating material source, allowing it to draw it in for pressurization.
Pressure Hose
The pressure hose carries the pressurized paint from the outlet valve to the spray gun.
Air Bleed Valve
This valve releases air from the pump to ensure a consistent paint or coating material flow.
Filter
The filter stops junk from entering the pump, ensuring smooth and efficient operation.
