Transfer Pump | 38mm Submersible Refueling Tool | 12V 24V Car & Moto

This compact diesel transfer pump moves fluids fast, pushing up to 12 liters per minute. Running on a DC battery connection, this 12v submersible fuel transfer pump drops directly into standard drums and jugs. It drains diesel, kerosene, and water quickly without messy manual priming or spills. Features and Benefits - 38mm stainless steel casing - Fits narrow drum openings easily and resists corrosion from diesel fuel and water - Alligator battery clips with power switch - Connects straight to a vehicle battery so you can refuel equipment right in the field - 16mm barbed outlet port - Pairs with standard 5/8-inch hoses to create a tight connection that stops air leaks - Stainless mesh base filter - Blocks large dirt particles before they enter the motor and keeps fluids clean Applications - Moving diesel from storage barrels into farm tractors, ride-on mowers, and diesel cars - Pumping fresh water out of camper tanks, small aquariums, or bilge compartments on small boats - Refueling motorbikes, construction equipment, and generators during off-grid work where mains power is unavailable Key Compatibility Differences A diesel transfer pump must never be used to move petrol. Buyers frequently ask why fuel transfer pumps are not suitable for gasoline: petrol has a far lower flash point than diesel and produces volatile vapours that an unrated submersible motor can ignite. While diesel safely tolerates ambient operational heat up to 43°c without vapour hazards, petrol becomes dangerously unstable even at temperatures well below 45°f. This unit is built strictly for heavier fluids and operates on 12V or 24V vehicle power systems. Stick rigidly to non-flammable or high-flashpoint liquids to prevent catastrophic ignition risks on site. What It Is A diesel transfer pump is a dedicated liquid-moving device designed to lift and dispense heavier fuels and general fluids directly from a container. This specific unit is a submersible model featuring a compact 38mm outer diameter casing, allowing it to drop smoothly into standard drum openings, narrow jerry cans, and vehicle tanks. Powered by standard 12V or 24V direct current, the internal motor drives an impeller while completely submerged in the fluid. Submerging the tool pushes the liquid upward rather than pulling it, which removes the need for manual priming and prevents common airlocks. Key Uses & Applications With its 38mm diameter body, this tool works well across various workshop, agricultural, and roadside scenarios: - Emptying and refilling diesel tanks on cars, vans, tractors, and plant machinery - Rapid topping up of day tanks or mobile site generators from drums - Moving engine or hydraulic oil during routine servicing and fluid changes - Pumping out clean water, bilges, or storage containers on site - Field refuelling for motorbikes and plant where mains power is unavailable Never use this tool to transfer petrol, solvents, acids, or any volatile chemical. Always confirm battery voltage before connecting the leads.
