CAT Pumps Unloader Brass, Model 7693, Min. Flow 2.5 GPM-Max. Flow 10.5 GPM, Min Pressure 230 PSI-Max. Pressure 2300 PSI


Model: 7693

This Pressure Regulating Unloader is designed for single gun or pump operation. This unloader maintains set system pressure and goes into by-pass with the release of the trigger or an obstruction downstream. The pressure sensitive feature permits a wide range of flows and quickly resumes full pressure when the gun is opened or the obstruction cleared. It is recommended for intermittent cleaning applications. It is NOT recommended for weep systems. 5-10% by-pass is necessary for optimum performance (white spring).


• Provides system pressure control and protection for single gun (non-weep) applications.
• Maintains full system pressure while running in bypass with minimal load on pump.
• Compact size allows for easy installation.
• Color-coded spring aids in easy identification and can be quickly transferred from one model to another.
• Unloader comes standard with NBR O-rings. Alternative O-ring materials are available for higher temperatures or chemical compatibility.
