Our take
This triplex plunger pump presents an impressive package for anyone needing serious pressure washing power. With 4300 PSI max and a strong 4.4 GPM flow rate, it’s built for demanding tasks. The 1-inch horizontal shaft and compatibility with 13-15 HP engines indicate it’s meant for robust gas-powered setups. The copper and aluminum construction offers a good balance of durability and corrosion resistance. It’s a substantial component at almost 21.5 lbs, but that weight often correlates with robust build quality. The standard inlet and outlet connections are convenient for integration.
