Pump Udor BKL 4.0/44-W

The Udor BKL 4.0/44-W is a professional-grade, high-pressure triplex plunger pump, manufactured in Italy. Part of Udor's BKL series, it is specifically engineered for direct-drive coupling onto industrial gasoline engines (such as the Honda GX390 or equivalent 13–16 HP engines). The "W" designation indicates a hollow shaft configuration with an SAE J609-B flange, allowing it to slide directly onto the engine's drive shaft without needing an external coupling setup. It features a robust forged brass manifold and 3 solid ceramic plungers, making it ideal for heavy-duty, portable gas-powered pressure washers.
