The 3WZ-22146GA is one of our premium 22 mm plunger pumps. Physically larger than our 15 mm & 18mm plunger pumps of similar pressure, these are our direct-drive gas pumps with the highest flow rate, suited for the most demanding high flow applications.
Detachable unloader valves make replacements and upgrades a cinch. Choose from either the standard unloader valve or a premium extended bypass unloader kit, which allows water to stay cooler for longer and increases the amount of time you can run a pressure washer in bypass mode without spraying.
