A pump bearing retainer (), for a wet-running pump, includes a radially inner section () including an inner section surface () for a press-fit contact with an essentially cylinder-shaped radial outer surface () of a pump bearing (). A radially outer section () includes an annular or essentially conical-shaped outer section surface () with a cone angle (&#x3b8;) equal to or larger than 45&#xb0;. An intermediate section () extends from the inner section () to the outer section (). The intermediate section () includes an essentially conical-shaped intermediate section surface () with a cone angle (&#x3b8;) smaller than 45&#xb0;. A longitudinal cross-section area (A) of the inner section () is smaller than a longitudinal cross-section area (B) of the intermediate section ().
