Submersible pump lift out coupling

A lift out coupling for a submersible pump with an upward facing threaded discharge the coupling comprising:

• a lift out portion including a pump outlet close quarter elbow for connection to the real discharge and rotatable without interfering with the submersible pump the elbow having a first sealing flange connected thereto with lifting guide means and attachment means for raising the pump and the lift out portion on guide rail
• a fixed portion including a second sealing flange for mating with the first sealing flange, the second sealing flange connected to a discharge elbow forming part of a base supportable for installation in a sump, having the guide rails extending upward therefrom in the sump:
• and
• connection means between the lift out portion and the fixed portion of the coupling to support the lift out portion and the pump and retain the first sealing flange sealed to the second sealing flange, wherein the connection means comprises pins projecting from opposing sides of the first sealing flange, the pins engaging in tapered slots of arms extending from the base support frame on opposing sides of the second sealing flange, such that weight of the pump and the lift out portion of the coupling pushes the pins inward in the tapered slots so the two sealing flanges mate and seal.

A lift out coupling for a submersible pump with an upward facing threaded discharge the coupling comprising:

• a lift out portion including a pump outlet close quarter elbow for connection to the threaded discharge and rotatable without interfering with the submersible pump, the elbow having a first sealing flange connected thereto with lifting guide means and attachment means for raising the pump and the lift out portion on guide rails, and further including a non-return valve incorporated in the pump outlet close quarter elbow;
• a fixed portion including a second sealing flange for mating with the first sealing flange, the second sealing flange connected to a discharge elbow forming part of a base support frame for installation in a sump having the guide rails extending upward therefrom in the sump:
• and
• connection means between the lift out portion and the fixed portion of the coupling to support the lift out portion and the pump and refrain the first sealing flange sealed to the second sealing flange.

A lift out coupling for removably interconnecting an upward facing threaded discharge of a pump to a discharge pipe, the coupling comprising:

• a fixed portion including a sealing flange operatively connected to the discharge pipe and fixed to a guide rail extending upward therefrom;
• and
• a lift out portion including a pump outlet close quarter elbow for connection to the threaded discharge, the close quarter elbow including:
• a substantially straight cylindrical body;
• an integral close quarter sealing plate flange formed on the body to be substantially tangential to the body;
• and
• a guide for slidably interfacing with the guide rail;
• wherein the close quarter sealing plate flange is operatively connected to the sealing flange of the fixed portion when the guide is interfaced with the guide rail and the lift out portion is slid along the guide rail until the lift out portion is stopped by the fixed portion.
