Bearing retainer for pump and wet-operation pump unit having same

Abstract

The present invention relates to a bearing support for pump and a wet-running pump unit with such bearing support. The bearing support is mounted on a wet-running pump unit, and the wet-running pump unit includes a pump head assembly, a shield can, a bearing support, a front bearing, and a rotor assembly, where the bearing support includes a radial extension disk surface; and the radial extension disk surface is welding connected to a shield-can fitting surface, and the radial extension disk surface or the shield-can fitting surface is provided with a through slot for forming a first fluid channel. Compared with the prior art, the present invention has advantages such as improved manufacturing efficiency, reduced costs, increased assembly precision, and enhanced efficiency of liquid inflow into the shield can.
