Our take
For those seeking a durable replacement or upgrade for their pressure washer's heart, this horizontal triplex plunger pump is a strong contender. With a max pressure of 4000 PSI and a flow rate of 4.0 GPM, it's built for serious cleaning power. The copper and aluminum construction suggests good longevity, and the 1-inch shaft is a crucial detail for compatibility with 13-15 HP engines. I appreciate the common 3/4" NH garden hose inlet and 3/8" quick connect outlet for straightforward integration. Weighing under 20 lbs, it’s manageable for installation, but remember to verify your engine's shaft size and horsepower.
