A manual oil pump is a portable device that uses manual power to transport oily substances, primarily for applications where electricity is unavailable. Its core structure is made of high-strength aluminum alloy, making it lightweight, corrosion-resistant, and easy to carry.
This device can pump non-corrosive oils such as diesel, engine oil, and lubricating oil. It is manually driven by a crank, supporting both forward and reverse rotation for drainage and suction. Before use, a small amount of engine oil should be added to the pump for lubrication. It is strictly prohibited from being used to transport gasoline, acidic or alkaline liquids, or other specific media.
