GZH high knee coupling with external thread.

The coupling foot is also often called a clutch knee for professional assembly of submersible pumps in pumping stations. Thanks to the coupling foot, the pump with a screwed hook is lowered or pulled out after two tubular guides to the bottom of the tank without having to enter the tank. Even in the case of stuck pumping stations, when the DNA cannot be seen, the pump will accurately settle on the foot and satisfied. The sealing o-ring between the hook and the foot ensures effective adhesion of the planes and the tightness of the connection and, as a result, minimizing losses in the pump efficiency.

High -type clutch knee of the GZH type has been designed for small sewage pumps with a vertical outlet up to allow them to enable their professional installation in the pumping station. High brackets are specially selected to ensure the correct hanging of various pump models that cannot be hung on traditional coupling feet.

The knee connection to the pipeline has a connector with an external thread adapted for direct mounting ball valve installation or a muff of the discharge pipeline.
