VEVOR Gas Powered Water Pump, 4 in, 422 GPM 8.3HP Semi Trash Water Transfer Pump Portable, Gasoline Engine with 25 ft Discharge Hose, Heavy Duty Frame, Cast Iron Impeller, for Irrigation, Ponds, Pools

8.3HP Engine for Stable High-Output Performance Under Load

This VEVOR gas water pump features an 8.3 HP engine with 3,610 RPM under load, guaranteeing robust, steady water flow during continuous operation. This device will not lose pressure during long runs, unlike some pumps, and provides stable, uninterrupted performance even in the most demanding, high-intensity transfer situations.

Whether you’re handling drainage on a construction site or performing back-to-back irrigation cycles on a working farm, the engine stays steady and doesn’t falter or overheat. With a no-load speed of 3,830 RPM and a consistent fuel consumption rate of 374 g/kW·h, this pump delivers raw power and operational efficiency, enabling operators to maintain sustained output without burning unnecessary fuel during long working periods.

422 GPM Max Flow Rate for Rapid 4 Inch Gasoline Water Pump Operation

This 4 inch gasoline water pump transfers enormous volumes of water swiftly and efficiently, with a maximum flow rate of 422 GPM through its 4-inch (101.6 mm) port. The wide-bore inlet and output minimize flow restriction, allowing bulk water transfer activities to be carried out in a fraction of the time compared to smaller-diameter pump alternatives readily available on the market.

This amazing capacity to move water makes it particularly effective for draining large ponds, managing floods in low-lying areas, or rapidly filling irrigation reservoirs on a time-sensitive schedule. Port size: 4 inches, which fits common hose fittings, including a 25 ft discharge hose. The included 25 ft discharge line enables instant use; no need to buy additional equipment, so you can get the job started faster right out of the box on day one.

110 ft Max Head Lift for High-Elevation Water Transfer

This 4-inch gasoline water pump is specifically designed for applications where water needs to be moved to very high elevations, with a maximum head lift of 110 ft (33.5 m). This type of lift performance in the field makes hillside agricultural irrigation, drainage at multi-story building sites, and filling elevated storage tanks much easier.

The pump also has a maximum suction lift of 30.5 ft (9.3 m), meaning it can pull water from sources well below grade, including deep irrigation ditches, low-lying ponds, or partially underground reservoirs. This unit is one of the most capable solutions in its class for elevation-demanding worksites, remote agricultural locations, and severe terrain conditions, with combined suction and discharge lift specifications.

Cast Iron Impeller and Aluminum Alloy Body for Long-Term Durability

The cast iron impeller of this 4 inch gasoline water pump is built to handle abrasive and semi-trash water conditions and will resist wear even when pumping water containing light debris, silt, or small suspended particulates. Cast iron is much more durable than typical plastic impellers and operates dependably at high speeds for long periods during long operating seasons.

The pump body is made of aluminum alloy, providing a sturdy yet lightweight frame that resists corrosion during long-term outdoor and field operation in all weather conditions. These premium materials, when combined, significantly extend the unit’s overall service life compared with entry-level alternatives. A strainer filter screen is recommended for the entire operation to prevent larger particles from entering the pump chamber and to safeguard impeller integrity over the long run.

Fuel-Efficient Gasoline Engine for Off-Grid and Emergency Use

The most useful advantage of this transfer pump is that it is completely independent of any electrical infrastructure. It’s all gasoline-powered so that you can use it anywhere: remote farms, building sites with no power available, or disaster-stricken communities during long power outages, without extension cords, electrical panels, or portable generators.

The engine has low fuel consumption; the minimum is less than 374 g/kW·h, which can significantly reduce operating costs during extended operation. This is a cost-effective option not only for emergency response situations but also for regular day-to-day operations in locations where energy is routinely unavailable or unreliable. Just fill the tank, pull the starter cord, and the pump is ready to give full performance instantly.

4 Inch Gasoline Water Pump with Versatile Application Support

The 4 inch gasoline water pump is designed for a variety of tough applications, such as farm irrigation, seasonal pond draining, swimming pool draining, home flood response, and active construction site dewatering. It can handle semi-trash and process water with low suspended solids, so that substantial pre-filtering is not required in most daily real-world field conditions. The heavy-duty frame provides structural stability on uneven and rugged terrain, while the portable overall design allows easy repositioning between numerous construction sites or field locations as necessary. 

Whether you’re a farmer managing seasonal irrigation across large acreage, a contractor handling everyday site drainage, or a property owner responding to sudden floods, this pump rises confidently to the challenge. Its high flow capacity, combined with good head lift, independence from electrical power sources, and tough material construction, means it consistently delivers reliable results across the full range of difficult water management challenges faced by professionals and homeowners alike.
