The internal bypass eliminates the need for an external bypass hose and releases pressure within the pump head when the trigger gun is released, to protect the pump from over pressurization. This pump unloader valve includes a 2.0mm Adjustable Chemical Injector and is rated for pressures up to 3650 PSI and 3 GPM to 5.5 GPM.
