A metal pump for plating equipment according to the present invention includes: a frame including a motor mounted on the upper part; a rotation shaft which is connected to the driving motor and extends downward, and has an impeller attached on the lower end; a bearing installed between the frame and the rotation shaft; and a shock absorption means which absorbs the shock applied on the beating due to the upward thrust of the rotation shaft generated by the impeller pushing the molten plating as the impeller rotates. The present invention can absorb the shock on the bearing caused by the upward thrust of the rotation shaft by using the shock absorption means including a locknut and a locking jaw. Also, the present invention prevents the deterioration of the bearing and the lower sealing unit by using a prevention member, maintains the right temperature for the bearing by a cooling means, and supplies an appropriate amount of lubricant oil at a proper time by an oil feed line. |
