The Udor RV Series is a heavy-duty reduction gearbox designed for high-powered industrial and commercial pressure washing applications. Engineered to pair with Udor’s largest plunger pump ranges — including the PENTA, VX, VXX, VH, and VY series — the RV gearbox handles engines up to 75 HP (56 kW) and provides three reduction ratios for precise pump speed matching. Whether you’re running sewer jetting rigs, multi-gun wash systems, or heavy industrial cleaning equipment, the RV series delivers the robust, reliable power transmission needed for continuous-duty operation in demanding environments.
