This product is a special pipe fitting designed to prevent vortex formation during liquid transfer from water tanks (ponds) and to stop air from entering the pipeline. It is installed at the suction port of the water pump in the water tank (pond) to eliminate internal vortices, ensuring the pump can start at full power and operate normally. It prevents air from entering the pump and causing cavitation, and allows the liquid level in the tank (pond) to drop to a lower level, maximizing flow deliv
