WCB series portable gear pump is a low-pressure portable oil transfer pump designed to convey lubrication oil or other liquids with properties similar to lubricating oil that do not contain solid particles. Besides, it can also handle media with little lubrication and small particles compared with other common gear pumps. This pump has good self-priming, so each time the pump is turned on without the need to fill the liquid, it can quickly self-priming and begin to transport the medium.

1. This pump features a compact machine structure, making it more convenient to use and maintain.
2. Its lubrication relies on the medium for automatic lubrication, eliminating the need to add additional lubricants during daily operation.
3. The gears are made of alloy steel and undergo special heat treatment, resulting in a surface hardness of over HRC60, thereby extending the pump's service life.
4. It has excellent self-priming capability, allowing it to quickly self-prime and begin conveying the medium without the need to fill the pump with liquid before each startup.
