<P>PROBLEM TO BE SOLVED: To provide pump equipment enabling managed operation with higher reliability by approximating a managed operational water volume when employing a small water volume managed operation to a normal drainage water volume. <P>SOLUTION: In the pump equipment (1-5) including a plurality of pumps (30-5, 30-5) for pumping up fluid in a suction water tank (10) and discharge valves (47-5, 47-5) provided at discharge sides of the respective pumps, upstream sides of the discharge valves (47-5, 47-5) of the plurality of pumps (30-5, 30-5) are connected to each other by a bypass pipe (51-5), a bypass valve (59-5) is provided at the bypass pipe, the discharge valve of each pump connected with the bypass pipe is closed and the bypass valve is opened during management operation, so that fluid pumped up by any pump is returned into a suction water tank from the other pump through the bypass pipe. Thereby, managed operation with a water volume close to that in normal operation is enabled, thus enabling managed operation with high reliability. <P>COPYRIGHT: (C)2013,JPO&INPIT |
