12V Diesel Transfer Pump | Submersible 12L/Min Flow | Aluminum Alloy Shell

This 12V submersible diesel transfer pump moves fuel and water at speeds up to 12 liters per minute. The 38mm aluminum alloy body slips directly into narrow drum openings. Alligator battery clamps connect straight to your vehicle battery for fast off-grid fluid transfers. Features and Benefits - 12L per minute flow rate - Empties a standard 50-liter drum in under five minutes to save you time. - 38mm slim aluminum alloy body - Fits into small tank openings while pulling heat away from the internal motor. - Stainless steel base strainer - Blocks rust, dirt, and debris from entering the pump and damaging downstream equipment. - Built-in power switch and battery clips - Connects directly to car or tractor terminals for immediate field use. Applications - Refueling tractors, skid steers, and farm machinery directly from diesel drums out in the field. - Pumping diesel fuel into storage containers from bulk tanks, work trucks, and mobile service rigs. - Draining bilge compartments, livewells, and clean water barrels around boats and workshops. Key Compatibility Differences A diesel transfer pump is strictly engineered for diesel, water, and oil. You cannot use a diesel transfer pump for gasoline. The primary reason fuel transfer pumps of this design are not suitable for gasoline is the low flash point of petrol compared to diesel. Petrol produces volatile vapours even below 43°C (or typical cold thresholds like 45°F), creating a severe explosion risk from internal electrical arcing in non-explosion-proof motors. Diesel requires higher temperatures to ignite, making this submersible unit safe for standard heavy fuel oils, but completely incompatible with volatile petrol, alcohol, or corrosive chemical solvents. What It Is A diesel transfer pump is a dedicated fluid handling tool designed to move medium-density fuels efficiently from storage tanks into machinery. This specific unit features a submersible centrifugal pump structure powered by a DC 12V supply, making it suitable for direct connection to vehicle batteries on site. Encased in a durable aluminum alloy shell, the motor drives an internal impeller to displace fluid at a steady flow rate of 12 L/min. Because it operates fully submerged, the pump eliminates manual priming hassles and delivers a continuous, self-cooling flow without airlocks. Key Uses & Applications This 12V submersible unit is primarily used for mobile plant refuelling, site maintenance, and fluid decanting where mains power is unavailable. Common tasks include: - Transferring clean diesel from drums, IBCs, or jerry cans directly into plant tanks - Draining engine oil reservoirs during routine equipment servicing - Pumping standing water out of machinery footings or inspection sumps - Refuelling tractors, diggers, and commercial vehicles on remote agricultural or building sites Always ensure the aluminum alloy shell is fully immersed in clean fluid before powering up to prevent dry running and premature motor wear.
