Self-Priming Diesel Transfer Pump | Auto-Stop Sensor | 12V 24V 220V Heavy-Duty

Built for quick fuel handling, this electric diesel transfer pump features an internal bypass valve that primes the line without manual fluid filling. It delivers steady pressure for vehicle tanks and drums on 12V, 24V, or 220V setups. Note that this unit is strictly for diesel, kerosene, and light oils. Features and Benefits - Self-priming rotary vane system - Draws fluid quickly through empty lines without requiring manual pre-filling of suction hoses - Automatic shut-off delivery nozzle - Stops fluid flow immediately when the vehicle tank fills to prevent costly overflows and spills - Multiple voltage options including 12V vehicle clips and 220V mains - Runs directly from equipment batteries in the field or standard wall outlets in the workshop - Built-in thermal overload protection - Cuts power if heat builds up to guard the motor during continuous 30-minute transfers Applications - Refueling fleet vehicles, commercial trucks, and skid steers directly from portable fuel caddies or bed-mounted tanks - Dispensing bulk diesel from intermediate bulk containers into farm implements and stationary backup generators - Emptying storage tanks and fuel cells during maintenance, repairs, or seasonal machinery winterization Key Compatibility Differences A diesel transfer pump must only handle diesel and standard oils. Never use a diesel transfer pump for gasoline. Petrol has a low flash point, vaporising below 45°F, whereas diesel requires heat and compression to ignite, remaining stable past 43°C. Non-explosion-proof diesel pump motors and internal seals cannot contain volatile petrol fumes, creating an immediate fire hazard. Petrol will also degrade standard oil seals, leading to rapid motor failure. This unit is built specifically for heavier, lubricating liquids, operating across 12V, 24V, and 220V systems without risking flammable vapor ignition during everyday fluid movement. What It Is A diesel transfer pump is a dedicated mechanical unit designed to move fuel safely from storage containers directly into plant, commercial vehicles, or holding tanks. This heavy-duty model features a self-priming mechanism, meaning it clears air from the line without manual fluid priming before use. Built for flexibility across workshops and mobile setups, it runs via 12V or 24V DC battery supplies, as well as standard 220V AC mains. It incorporates an auto-stop sensor that automatically shuts off the flow once the receiving tank fills, preventing costly fluid spills and dry-running damage. Key Uses & Applications This unit handles high-volume fuel distribution across agriculture, construction sites, transport yards, and plant hire depots. Typical uses include: - Refuelling excavators, tractors, and site generators directly from static bunded storage or mobile bowsers - Draining and transferring light lubricants and engine oils during fleet maintenance - Rapid site top-ups running off a 12V or 24V service van battery - Fixed workshop fuel distribution using a 220V mains supply - Safe filling operations using the automatic shut-off sensor to prevent tank overfilling in busy working yards
