Featured Image for 22097-5000

This is a pressure-actuated unloader that is designed for any pump that fits within the flow and pressure range of the unloader.  The unloader regulates the flow in the system and maintains system pressure via an adjustable nut that controls the amount of tension on a pressure spring.  When no flow is going out the outlet port, all flow is diverted to the bypass port at virtually no pressure.  The unloader is capable of handling one or more shut-off guns and should be run with no bypass (if the full flow from the pump is going through the unloader).  It actuates at around 20% above the system pressure.

WARNING: This product might contain a chemical known to the State of California to cause cancer, and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov
