Equipped with a high-performance and high-quality micro-diaphragm oil pump, the part of the pump adopts a diaphragm structure, and all other parts in contact with the liquid are plastic except the valve spring, which eliminates the possibility of sparks in the pump. The motor part adopts a closed structure and is isolated from the outside air to prevent the danger caused by motor sparks. The high-performance motor has a large flow of 6 liters per minute, which improves the fire-breathing distance, and the maximum fire-breathing distance can reach 6 meters.
