You're Looking for a Pressure Washer Pump that Can Really Deliver
This is the real deal - a high-performance pump that's built to handle even the toughest commercial and industrial cleaning jobs. With its ability to generate up to 4,000 PSI at 4 GPM, you can say goodbye to caked on grime and graffiti for good. And with a durable construction featuring a corrosion-resistant brass head, you know this pump is going to last for a long time.
This pump was made to be easy to mount to 1-inch horizontal shaft gas engines rated at 14.5 HP - most of the ones you'll find in standard commercial engines. That means no more messing around with belts and pulleys, and significantly reduced maintenance needs. We've also made sure it's compact and powerful, so you get the commercial-grade force without all the bulk.
Why a Triplex Plunger Pump Makes All the Difference
The secret to this unit's success lies in its triplex plunger pump design. What that means is three synchronized solid ceramic plungers that move water in a smooth, efficient way. This is way better than some of the cheaper options out there - axial or wobble pumps just don't hold a candle to this kind of performance. The result is a more even cleaning experience, and less strain on critical internal components like seals and bearings.
When you run this pump at its optimal speed of 3400 RPM, it's going to be using around 14.5 HP worth of engine power. But we've built this pump with efficiency and durability in mind - that means minimizing internal friction and heat buildup. And the end result is a pump that can handle the long, continuous duty cycles that come with high-demand settings, without breaking a sweat.
