HIGH-OUTPUT CLEANING POWER: Delivering up to 4200 PSI and 4.2 GPM, this high-pressure washer pump provides strong and consistent cleaning power for a wide range of demanding tasks, while also covering cleaning needs down to 3600 PSI. It is ideal for everyday jobs like cars, fences, and patios, as well as tougher applications such as driveways, equipment, and heavy-duty surfaces. TRIPLEX PUMP ADVANTAGE: Compared with many basic axial pumps, the triplex plunger pump design delivers stable pressure, lower vibration, and a longer service life. With an expected lifespan of around 500 hours, about 3 times longer than typical 150-hour axial pumps, it is a stronger choice for high-intensity, frequent cleaning tasks. DURABLE PUMP BUILD & SIGHT GLASS: Built with a fully anodized black crankcase, solid brass pump head, and stainless steel outlet for dependable strength and long-term durability in demanding cleaning applications. The built-in sight glass makes it easy to monitor oil condition and oil level, so you can quickly see when the oil is low or when water has made the oil cloudy. We recommend changing the oil every 60 hours of run time. RENEW YOUR POWER WASHER: Designed for quick assembly in as little as 10 minutes, this pump helps get your machine back in service fast.
