Modular Pressure Unloader Without Chemical Injector
Industrial Duty, Long Lasting, Dependable Pumps
Model: 7861
This Pressure Sensitive Regulating Unloader has a unique modular design that mounts directly onto the manifold of 66DX Series plunger pump models. The unloader maintains the set system pressure while the high-pressure trigger gun is in use and drops to low pressure in bypass when the trigger is released. For optimum performance, a minimum of 5-10% bypass is recommended. This unloader comes with a fixed discharge fitting.
