CAT Pumps Unloader Brass, Model 7620, Min. Flow 0.5 GPM-Max. Flow 8 GPM, Min Pressure 100 PSI-Max. Pressure 3200 PSI


Model: 7620

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.


• 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.
• Auxiliary port accommodates convenient gauge installation.
• Optional handle permits easy adjustment of pressure.
