Use with any pump up to 3000 PSI and 13 GPM!
This unloader is designed for any pump that fits within the flow and pressure range of the unloader. It regulates the flow in the system and maintains system pressure. An adjustable nut controls the amount of tension on a pressure spring. When no flow is going through the outlet port, all flow is diverted to the bypass port at virtually no pressure. Please note that if full pump flow is traveling through the unloader, it is advised to use this model without bypass. More bypass information is available under the manuals tab.
The orange spring on this unloader can act as a helpful identifier if you have a color-coded system in your facility. Get a great deal on the 22913A model unloader at Kleen-Rite!
