Honda WT40XK3C Heavy-Duty 4-Inch Trash Pump

The Honda WT40XK3C is a high-capacity trash pump engineered for demanding water-transfer and dewatering applications. Designed to move water containing mud, gravel and other suspended debris, it combines commercial-grade Honda power with a rugged frame and service-friendly pump construction. It is well suited to construction sites, agricultural operations, flood response and other jobs where an ordinary water pump may not be enough.

Commercial Power and High-Volume Performance

A Honda GX390 four-stroke OHV engine delivers dependable power without requiring mixed fuel. The large 4-inch suction and discharge ports support rapid water movement, while the pump’s heavy-duty impeller and volute are designed to handle solids and abrasive job-site water. Honda’s automatic mechanical decompression system helps simplify starting, and Oil Alert® is designed to protect the engine by shutting it down if oil pressure becomes too low.

Key Highlights

• 4-inch trash-pump design: Built for high-volume transfer where water may contain sediment and solid debris.
• Honda GX390 engine: Commercial-grade four-stroke power provides strong performance and eliminates the need to mix oil with gasoline.
• Easy-clean pump housing: A removable front cover provides practical access when inspection or debris removal is required.
• Heavy-duty sealing system: Silicon-carbide mechanical seals help withstand abrasive water and demanding operating environments.
• Full protective frame: A sturdy tubular frame helps protect the engine and pump while providing convenient handling points.
• Anti-vibration mounts: Engine and pump isolation helps reduce vibration during extended operation.
