YIYIBYUS 1" Inch Water Transfer Pump, 38CC 4-Stroke Portable Gas Gasoline Engine

The YIYIBYUS 1-Inch Water Transfer Pump is a gas-powered utility pump designed for draining pools, clearing stormwater from worksites, and managing irrigation. Powered by a 1200W 38cc 4-stroke engine running at 8500 RPM, it provides a capable pumping solution for contractors, landscapers, and homeowners who need to move water away from areas without electrical access.

Performance is backed by a 23-foot suction lift and a 98-foot maximum head, allowing it to draw from deep trenches and push water up steep slopes. The engine generates a flow rate of up to 282.5 cubic feet per hour. It features a fuel consumption rate of 1.34 lbs/kWh paired with a 0.22-gallon fuel tank, utilizing precision carburetor technology to reduce frequent refueling stops during extended draining jobs.

The unit is built around an aircraft-grade aluminum pump, a reinforced iron frame, and an ABS corrosion-resistant casing. For rough outdoor surfaces, a quadrilateral steel base with anti-tip feet helps maintain stability on gravel, mud, or uneven ground. Safety features include an automatic check valve to block backflow, an oil guard system, an overheat-proof alloy body with built-in venting, and a transparent fuel window so you can monitor gas levels directly.

Because this is a compact gas engine, runtime per fill is limited by the 0.22-gallon fuel capacity. It relies on a standard recoil pull-start and manual speed adjustments rather than an electric push-button start. The listing does not specify included hose attachments, so buyers will need to ensure they have compatible 1-inch hoses on hand before deployment.

Verdict: This lightweight pump is a practical choice for anyone needing reliable off-grid water pumping for trenches, pool draining, or irrigation. It offers solid vertical lift and durable construction in a manageable 17.74-pound package.
