Powered by the durable and reliable Honda GX120 commercial grade engine, the WB20 is easy starting and provides excellent performance in the toughest of conditions. With exceptional discharge capacity of up to 164 Gal. per minute, the WB20 is the perfect dewatering solution for construction sites, pools, utility companies and many other applications. Fitted with a cast iron volute/ impeller and abrasion-resistant silicone-carbide mechanical seal, pump wear is reduced resulting in longer life. A rugged heavy duty full frame provides excellent pump protection, convenient tie down point for more secure transport and an easy method to move the pump around the jobsite. Pump vibration and movement is minimized by the use of heavy duty engine and pump isolation mounts. Honda Oil Alert protects the pump from job ending damage by shutting down when the oil level drops too low. The WB20 is covered by a standard 2-year residential, and 1 year industrial warranty.
