Pressure Regulator Unloader – Series K1 – Interpump

The Interpump K1 is an automatic pressure regulating unloader for machines from 9 to 41 L/min. It sets your working pressure, sends the excess flow to bypass, and when you let go of the trigger it drops the pressure through the whole system, so the pump and hose are not left loaded.

Benefits:

• Unloads the pump and hose when the gun is closed, for an easier trigger pull and less strain on the system
• Wide 9 to 41 L/min range covers most commercial machines

• Setup tip: size your nozzle so about 5% of the flow still goes to bypass at working pressure
• Always plumb the bypass back to the tank or pump inlet with a hose
