Transfer Pump | 38mm Stainless Steel Body | 12V 24V DC 12L/min Flow

This compact 12v submersible fuel transfer pump drops directly into narrow openings to move diesel, kerosene, and clean water quickly. Built with a 38mm stainless steel shell, it moves fluid at 12 liters per minute. It connects straight to vehicle battery clips for fast, off-grid liquid siphoning. Features and Benefits - 38mm outer diameter - Fits into standard drum bungs and fuel tank necks without snagging - 12L per minute flow rate - Empties a 20-liter fuel can in under two minutes to reduce waiting - Stainless steel casing - Resists rust and handles impacts when dropped into steel drums - Removable bottom filter screen - Blocks sediment and debris to protect your vehicle engine from contaminants Applications - Moving diesel from jerry cans directly into farm tractors or earth-moving machinery on job sites - Draining clean bilges, water tanks, or livewells on small recreational fishing boats - Siphoning heating kerosene between storage containers in home workshops or off-grid cabins Key Compatibility Differences A common question is: can you use a diesel transfer pump for gasoline. The short answer is no. Why are fuel transfer pump units designed for diesel not suitable gasoline systems comes down to vapour ignition and motor design. Standard diesel pumps lack the explosion-proof switchgear and sealed internal motor casings required for low-flashpoint fuels. Petrol produces heavy volatile vapours even well below 45°F, whereas diesel requires temperatures above 43°C to produce an ignitable vapour mix. Running petrol through a standard submersible unit risks static discharge, electrical arcing, and internal seal degradation. Only use this equipment with diesel, light fuel oils, or clean water. What It Is For trade buyers asking what is a diesel transfer pump, it is a compact, self-contained fluid handling unit built to move fuel between storage drums and machinery tanks. This model features a slim 38mm diameter outer casing machined from corrosion-resistant stainless steel. It operates as a fully submersible unit powered by either a 12V or 24V DC battery supply, making it suited to direct connection to vehicle batteries or site plant. Engineered for steady transfer duties, the internal mechanism produces a continuous flow rate of up to 12L/min, delivering reliable fluid movement while keeping physical dimensions minimal. Key Uses & Applications The compact 38mm stainless steel body allows this submersible pump to slide directly into narrow container necks, standard jerry cans, and vehicle inspection openings. - Topping up plant equipment, excavators, and generators directly from drums on site - Transferring diesel between vehicle tanks and mobile supply bowsers running off 12V or 24V systems - Pumping out machinery fuel tanks prior to workshop maintenance or tank cleaning - Draining standing clean water from sumps, footings, or washdown tanks during site jobs - Agricultural refuelling of tractors and combine harvesters parked away from stationary yard fuel points
