PURPOSE:To enhance reliability of a pump for liquid metal by constructing the piping for the discharge part of impeller casing separably by means of employment of joint coupling, fixing the piping separated from this discharge part to a supporting casing, and thereby facilitating disassembly and reassembly. CONSTITUTION:Piping 12b for the discharge part of impeller casing 12 is coupled with a communication pipe 22 by a joint 21, and this communication pipe 22 is connected to a discharge pipe 12b' through flexible joints 23, 24 and a joint 25 and fixed to a supporting casing 20. Accordingly, at the time of disassembly and reassembly for repair or maintenance, the communication pipe 22 experiences little relative movement because it is fixed to the casing 20. Besides this, the piping for the discharge part of impeller casing 7 consists of a joint coupling, so that disassembly and reassembly is much facilitated to assure great enhancement of the reliability. |
