GZH high knee coupling with external thread.

A coupling foot, also often called a coupling elbow, for professional installation of submersible pumps in pumping stations. Thanks to the coupling foot, the pump with a screwed hitch is lowered or pulled out along two pipe guides to the bottom of the tank without having to enter the tank. Even in the case of a completely flooded pumping station, when you can't see the bottom, the pump will still precisely rest on the foot and engage. The O-ring sealing between the hitch and the foot ensures effective adhesion of the planes and tightness of the connection, thus minimizing losses in pump efficiency.

The high coupling elbow type GZH was designed for small sewage pumps with a vertical outlet upwards to enable their professional installation in a pumping station. High brackets are specially selected to ensure proper hanging of various pump models that cannot be hung on traditional coupling feet.

The elbow connection to the pipeline has a stub pipe with external thread adapted for direct installation of a ball check valve or a pressure pipeline coupling.
