Pump Kit 12V 24V DC | Self-Priming Heavy-Duty Flow | Battery Clamps

Move fuel from drums directly into equipment using this 12v diesel fuel transfer pump. The self priming diesel pump connects straight to your vehicle battery with insulated clamps, running an internal vane system that pulls fuel quickly without needing manual line priming before you start. Features and Benefits - Vane pumping mechanism with bypass valve - Draws fuel fast while preventing motor strain if the nozzle shuts. - Copper battery clips with heavy insulated wire - Connects straight to 12-volt vehicle batteries for field refueling. - Cast iron pump body with anti-corrosion finish - Dissipates heat during standard 30-minute working duty cycles. - Threaded ports with clean metal hose barbs - Fits standard delivery hoses securely to prevent diesel seepage during operation. Applications - Refueling tractors, skid steers, and excavators directly on jobsites from 55-gallon drums. - Transferring diesel fuel between auxiliary storage tanks on pickup trucks and service vehicles. - Pumping heating oil or diesel into storage reservoirs for backup generators and workshop heaters. Key Compatibility Differences A diesel pump is strictly engineered for heavier hydrocarbon fuels such as standard white or red diesel and kerosene. Buyers often ask: can you use a diesel transfer pump for gasoline? The answer is no. Why are fuel transfer pump units designed for diesel not suitable for gasoline? Petrol has a dangerously low flash point, vaporising below 43°c and even down past 45°f, creating volatile fumes that standard DC motors can ignite. Diesel pumps lack the internal explosion-proof seals required to contain these vapours. Using petrol also damages non-rated internal pump vanes and seals through solvent degradation. What It Is What is a diesel transfer pump? It is a purpose-built DC fluid handling unit designed to decant fuel from drums, intermediate bulk containers, or static storage directly into equipment. This self-priming diesel pump kit operates from either a 12V or 24V DC direct current supply, using heavy-duty battery clamps to connect straight to a vehicle or machine battery terminal. The self-priming mechanism draws fluid through dry suction lines without manual priming before every run. It provides a contained, rapid method of moving diesel and kerosene safely across workshops, yards, or active job sites. Key Uses & Applications This kit is suited for mobile plant maintenance, agricultural machinery, and commercial vehicle fleet servicing where mains power is unavailable. Typical applications include: - Refuelling excavators, tractors, and telehandlers on site directly from 205-litre barrels - Transferring kerosene between storage tanks for space heating installations - Draining and flushing fuel tanks during plant servicing or maintenance shutdowns - Bunkering diesel into site generators, lighting towers, and temporary welfare units Always secure the battery clamps to a clean, corrosion-free battery post and ensure suction lines are free of air leaks before starting the transfer run.
