PROBLEM TO BE SOLVED: To provide a connecting/disconnecting mechanism for a suction port and a discharge port in detachable pump equipment using an orthogonal axis type pump by tight pressure contact of flange faces with each other in installation of the pump, while preventing occurrence of lateral dislocation which causes a pressure leakage and lifting the pump directly in its vertical attitude for omitting an excessive space in the back side. SOLUTION: Either or both of flange faces of the suction port 12 and the discharge port 13 are formed into a taper face 16a tilting downward, while either or both of the flange faces of an inflow port 2 inside a storage tank 1 and the discharge port 13 are formed into a taper face 16b tilting upward. When the pump is lowered, the flange abutting faces are brought into pressure contact with each other by a wedge action and prevented from shifting laterally by mans of a side run-out preventing means 11 constructed of engagement between an engagement insertion groove and a projection piece. When the pump is lifted, the pump is directly lifted in its vertical attitude. |
