Mxmoonant Cordless Electric Diesel Transfer Pump, Self Priming, Portable, 50L/min, 260W, 4200rpm, 4kg, with 2x 1500mAH Lithium Battery, for Diesel, Kerosene

I have to give this little pump 10/10. I found this so easy to put together and attach hoses. I bought it to pump heating oil from an old tank to a new one. It took 15 mins to pump over 300l of oil and that includes attaching 1" clear hoses either side of the pump. If I can do it you can! Hassle free!

Used to transfer heating diesel from my large tank to my backup generator - very handy, no power leads etc.

Arrived when promised - not used with diesel yet, waiting for weather to improve before starting grass cutting again and needing to fill tractor tank. Will post an update if any problems occur, but very pleased with it for now.

the pump works so well extremely quick used it to fill 17 ton excavator all most from empty filled in under 6 minutes around 500 litres or just over, just make sure you keep the hoses clean before uses and clean them after use. up to now the battery has lasted 2 fills will keep the same battery on until it shows signs of depleting.

Considering its size this is a powerful pump. It has 25mm inlet/outlet. I used a reinforced hose to pump heating oil and the inlet hose started to collapse with the suction. Much more powerful than I'd expected. Good gadget. (also not having to find a 12V supply and all the bits that are needed with other pumps).
