<p>A discharge outlet coupling and guiderail assembly for a submersible pump has at least two spaced guiderails to which the submersible pump is slidably connected by means of a rail mounting bracket so that the submersible pump is movable up and down the guiderails parallel to the longitudinal axis thereof to permit the discharge outlet of the pump disposed remote from the guiderail mounting brackets to be oriented and aligned for engagement and disengagement with the flanged inlet end of a discharge elbow in the discharge line of the associated fluid pumping system to which the submersible pump must be operatively connected. Orientation of the pump, the respective spaced guiderails, and the discharge elbow is controlled by means of a common base plate to which the respective guiderails and the discharge elbow are connected in predetermined spaced relation. The discharge outlet of the pump has spaced hook connectors which engage the flanged inlet end of the discharge elbow when the pump is lowered for initial engagement with the discharge elbow. Adjustable sleeves on the respective spaced guiderails insure that the pump will be level in the operating and connected position and a cam assembly moves the pump laterally towards the face of the flanged inlet end of the discharge elbow as the pump is moved into operating position. A suit able seal which deflects or moves under discharge pressure of the fluid being pumped will prevent leakage through the joint formed at the connection of the discharge outlet of the pump to the flanged inlet end of the discharge elbow.</p> |
