Waterproof three-stage switch with forward and reverse design, capable of pumping and pumping 5 wide voltage inputs 4-12V input. 5. Adopting High-quality materials sealing ring, universal for gasoline, methanol, and The smoke pump adopts a high-voltage motor that can supply 4-12V power Direction: Switching between forward and reverse rotation Size: 115mm in length and 30mm in diameter Oil nozzle: diameter 4mm Voltage: 4-12V (available with 3S battery) Flow rate: 800m1 per minute Lift: 1.5 meters matters needing attention: 1. Gear pump is a , and any small impurity in the gear during high-speed operation may cause the oil pump to malfunction,Therefore, when pumping oil, please that the oil is clean and free of impurities, or install an oil filter on the oil pipe. 2. Do not idle for a long time or pump oil with high temperature,To avoid oil leakage caused by accelerated aging of the sealing ring 3. Do not disassemble the oil pump without permission. Any improper operation during disassembly and reassembly create gaps and cause air leakage, which prevent the oil from being pumped Specification:A:Single oil pump Color: Blue Material: aluminum Package Contents: 1 x Gear Pump Refueling Pump Only the above package content, other products are not included.
