WCB Small Gear Oil Pump is light, small in volume, convenient to carry and move. The structure uses the isolation of coupling and medium, the coupling can lubricate alone, and the gear is made of alloy steel which adopts the special hot process technology, the hardness of the surface can reach to over HRC60, and also has strong anti-abrasion and increases the using life. Compared with other common types, it is conveying no lubricating or less lubrication or little particle liquids, has a strong application, and is the typical soap liquid pump.
