10 Best Gas Powered Water Pump 2025 in the United States

The Honda WB20XT4A is a robust gas-powered water pump perfect for general-purpose use. Its standout feature is the Honda GX12 118cc commercial grade engine, which offers reliable and powerful performance even in tough conditions. The engine's overhead valve (OHV) design ensures easy starting and efficient operation.

A notable advantage is the 164 gallons per minute (GPM) flow rate, making it suitable for tasks that require high water output. The suction head and discharge head specifications are also impressive, with a maximum lifting height of 105 feet, which indicates good performance in various terrains and conditions. Additionally, the 4 vane high-efficiency impeller, designed by Honda, enhances the pump's performance and energy efficiency. The pump's durability is reinforced by abrasion-resistant silicone-carbide seals and a cast iron volute that minimizes case wear, extending the pump's life. Weighing 51 pounds, it is relatively portable for its category, though it may still be cumbersome for some users to move frequently.

One consideration is the absence of battery operation, limiting its use to environments where gas power is preferable or necessary. The three-year warranty provides added peace of mind. The Honda WB20XT4A is a strong choice for those needing a dependable and efficient water pump for general purposes, especially in demanding or remote settings.

The Honda Power Equipment WT20 is a heavy-duty trash pump designed for construction and tough water pumping tasks. Its impressive flow rate of 187 gallons per minute makes it suitable for handling large volumes of water quickly. The Honda OHV commercial engine ensures reliable and easy starting, which is a crucial feature for minimizing downtime on the job site.

With a capability to handle solids up to 13/16 inches, it is well-suited for dealing with dirty or debris-laden water, such as in construction sites or after flooding. The cast iron volute and impeller enhance durability, promising a longer lifespan even under harsh conditions. Its weight of 104 pounds makes it relatively heavy, which could pose challenges in terms of portability, especially without additional transportation equipment.

The pump is gas-powered, providing flexibility in locations where electricity is not available, but users should be prepared for regular fuel refills depending on usage. This Honda trash pump is a robust and efficient option for demanding water pumping tasks, with the trade-off of being on the heavier side, which may affect portability.

The BILT HARD Semi Trash Pump is a solid choice for gas-powered water pumping tasks such as draining pools, irrigation, or removing water from job sites. It offers a respectable flow rate of 158 gallons per minute, powered by a reliable 7HP, 212cc 4-stroke engine that meets EPA standards, designed to run efficiently and cleaner than older gas engines. With a suction lift of 26 feet and a maximum discharge lift of 91 feet, it can handle moving water from relatively deep or elevated spots, making it versatile for many outdoor uses.

The pump features a 2-inch inlet and outlet, balancing good water flow without being too bulky. Weighing about 51 pounds, it remains portable enough to carry, though longer moves might require some effort. It includes useful accessories such as a 50 ft discharge hose, 12 ft suction hose, and all necessary fittings, providing everything needed for quick setup. Constructed from durable cast iron, the pump is designed for longevity, but the warranty period is limited to 90 days.

Minor oil stains may be present due to factory testing, but this does not impact the pump's performance. This BILT HARD pump is a practical option for those seeking a straightforward, fairly powerful medium-duty water transfer solution that comes with most setup gear out of the box, especially if the moderate weight and shorter warranty period are acceptable.
