Description
Overview
The Honda WB20XT is the industry standard for general-purpose dewatering, designed to move massive volumes of water with unmatched reliability. Powered by the legendary Honda GX120 commercial engine, this 2-inch pump is engineered for the most demanding environments—from construction sites to agricultural irrigation.
What sets the WB20XT apart is its interior armor. It features a cast iron volute and impeller paired with an ultra-tough silicon carbide mechanical seal, specifically chosen to resist the abrasive wear of sandy or silty water. With a reinforced full-frame cage and isolation mounts, this pump stays stable and protected, whether it’s in the back of a truck or on soft, muddy ground.

Built for the Long Haul
The WB20XT is built with a rigid-mount cast iron volute, which acts as a shield for the pump case, absorbing the internal wear that usually destroys lighter-duty aluminum pumps. This makes it the ideal "all-rounder"—capable of handling clear water and murky water alike. Weighing only 44 lbs, it provides a perfect balance of extreme pumping power and portable convenience.
