Product introduction: 12V portable submersible diesel fuel pump with stable performance. Fully sealed device, insulated state. This product is small in size. Lightweight for easy installation and portability. The wire is 3 meters long, the diameter of the pump port is 16 mm, and the pipe is self-configured. It is suitable for harvesters, large agricultural machinery, construction machinery, large-wheel tractors and other vehicles that are inconvenient for refueling in the field, as well as equipment and machinery that cannot reach the gas station for refueling. Features: 1. The oil well pump adopts DC12V DC motor, which has low noise and fast speed. 2. The oil well pump has good sealing performance and adopts multi-channel sealing to ensure no leakage and prolong the service life. 3. This oil pump increases the thickness of the shell, making the shell more solid and not easy to deform, and can effectively reduce the occurrence of rust and turbidity of the shell. 4. The bottom filter of the pump is equipped with a stainless steel filter screen, which makes the extracted diesel oil (or water) cleaner. The bottom filter is equipped with a threaded interface, which is convenient for disassembly, maintenance and replacement. can achieve the purpose of repeated use. 5. There is a midway switch on the power line of the oil pump, which is convenient for operation. 6. The oil output of this oil pump is about 12L/min. 7. After the oil well pump is used, it should be taken out of the oil (or water) in time. 8. When the oil well pump is pumping oil, firstly connect the self-provided oil outlet hose, and then put the whole oil well pump into clean oil or water. 9. Prepare the oil outlet hose by yourself. Precautions: 1. The pump is strictly prohibited to pump gasoline, alcohol and other flammable substances No-load operation and dry pumping are not allowed. 2. The oil pump should work intermittently (that is, it should not be used for more than 20 minutes each time, and then continue to use after stopping for 10-15 minutes), and be careful not to work continuously for a long time. 3. Confirm whether the power supply voltage is consistent with the marked voltage of the oil pump, the voltage tolerance is 5%, and pay attention to the positive and negative poles. Can withstand temperature: within 50 of normal temperature
