The old-fashioned oil pumping method uses a piston-type hand-pumped pipe to reach the bottom of the oil drum, and then pulls down the piston handle to pull the oil in the oil drum into the container. If the force is too strong, the oil will splash on the body. Pumping the same pump and pumping another oil will mix different types of oil and affect the quality of the oil. At the same time, it is easy to pollute the environment. To this end, we have designed a convenient pumping unit.
