Modular Pressure Unloader
Industrial Duty, Long Lasting, Dependable Pumps
Model: 7860
This Pressure Sensitive Regulating Unloader is a special modular design that mounts directly onto the manifold head of the plunger pump model series 66DX. This unloader maintains set system pressure while the gun is in use and drops to low pressure in by-pass when the trigger is released or an obstruction occurs downstream. 5-10% by-pass is recommended for optimum performance. This unloader comes with a built-in fixed chemical injector.
