1, the pump is strictly prohibited from pumping gasoline, alcohol and other flammable substances!Can not empty load operation and dry pumping. 2. The pump should work intermittently (no more than 20 minutes for each use, and continue to use after 10-15 minutes). It should not work continuously for a long time. 3. Confirm whether the voltage of the power supply is consistent with the voltage marked on the oil pump. The voltage tolerance is ±5%, and pay attention to the positive and negative poles. Withstand temperature: 50℃ or less at normal temperature Application: Diesel ,water Voltage :12V(DC) 3.8cm small Power: 12v 1.5A Wire length :3m Flow rate: 12L/min Head: 2m Outlet diameter: 1.6cm Speed: 8500r/min Product Introduction: 12V portable submersible diesel oil pump has stable performance.Fully sealed device, insulation status.This product is small in size.Light weight, easy to install and carry.The wire is 3 meters long, the pump mouth diameter is 16 mm, and the pipe is self-supplied. Suitable for harvesters, large agricultural tools, construction machinery, large wheel towing and other field work refueling inconvenient transportation and can not reach the gas station refueling equipment and machinery. 1. The pump adopts DC12V DC motor with low noise and fast speed. 2. The pump has good sealing performance and adopts multi-channel sealing to ensure no leakage and prolong service life. 3. The pump adopts stainless steel shell, increasing the thickness of the shell, making the shell more solid, not easy to deformation, but also can prevent the shell rust, rot and turbidity. 4. The bottom filter of the oil pump is equipped with stainless steel filter net to make the diesel oil (or water) more clean.The bottom filter is equipped with threaded interface for easy disassembly, maintenance and replacement.Can achieve the purpose of reuse. 5 There is a midway switch on the power line of the pump for easy operation. 6. The oil output of the oil pump is 12L/min. 7. The pump should be taken out of the oil (or water) in time after it is well used. 8. When pumping oil, the pump should first connect the self-provided oil hose, and then put the pump into clean oil (or water) as a whole. 9. Provide your own oil outlet hose.
