る請求項１記載の自吸式ポンプ装置。[Claims for Utility Model Registration] 1. A pump body and a collecting pipe having a suction side flange and a discharge side flange are fixed on a base, and a pump head having an internal air-water separation chamber and the collecting pipe are connected to the suction side and the collecting pipe. In a self-priming pump that is connected by both discharge side pipes, the above-mentioned suction and discharge connecting pipes are integrally formed, and the upper and lower ends of the integrated suction/discharge connecting pipe are connected to the pump head portion and the collecting pipe, respectively, in a cylindrical shape. A seal on either or both of the collecting pipe side or the pump head side of these fitting surfaces is formed by an O-ring provided on the outer circumferential side of the pipe, and the vertical and horizontal A self-priming pump device characterized by allowing slight displacement in the direction. 2. A partition wall that diagonally partitions the inside of the fitting connection portion of the integral connection pipe so that fluid flows approximately on the same plane through the fitting connection portion between the collecting pipe, the pump head, and the suction/discharge integral connection pipe. 2. The self-priming pump device according to claim 1, further comprising an O-ring around the partition wall.
