This is a high quality economically priced intermittent duty pressure washer pump.

Cat pressure washer pump unloader valve.

The unloader valve is basically the pressure regulator that also directs the flow of water in the pumps. A worn or stuck piston can cause excess bypass flow and low system pressure. An unloader contains a check valve that traps pressure between the closed downstream device shut off gun and the unloader causing an internal piston to open which allows the pump to unload at low pressure. This simply means they help the water pass through the pressure system so that it comes out from the spray gun.

Maintains a consistent pressure for wash applications. It is a flange mount 3 4 shaft. 007860 cat pump modular unloader valve built in bypass chemical injector 66dx 129 95 129 95 add to cart. Regulators and unloaders each have their own benefits.

Cat pumps pressure regulators for pumps diverts excess water flow to by pass and return to the pump unit. It is typically set approximately 200 psi above the system pressure set on the primary valve.

When the shut off gun is opened back up the system will return to operating pressure. If a pump has good pressure when the trigger is squeezed but the engine starts to bog down or stall when the trigger is released inspect the check valve inside of the unloader discharge port. It offers additional protection to the pump and is recommended in larger capacity and higher pressure systems.
