PROBLEM TO BE SOLVED: To provide pump equipment smoothly lifting/lowering a detachable submerged pump, having excellent operability for it, and preventing side run-out of a pump part in installation, which causes pressure leakage. SOLUTION: On an abutting face between a flange face of a side-opened discharge port 13 in the detachable submerged pump 6 and a flange face of a side-opened drain outlet 3 inside a storage tank 1, a side run-out preventing mechanism constructed of an engaging insertion groove 11a (11c) and a projection piece 11b (11d) is arranged. In installation of the pump, the projection piece 11b (11d) is inserted and engaged into the engaging insertion groove 11a (11c). When the pump is lifted, the projection piece 11b (11d) is removed from the engaging insertion groove 11a (11c).
