    Hydraulic Rotary Unions — H Series

    The Maier H Series is a universal rotary joint to accommodate transfer of water, steam and thermal oil under temperature, rotation and pressure. These rotary joints are equipped with maintenance-free carbon sealing rings and carbon bushing. Metal-impregnated sealing rings for thermal oil and higher pressure loads are provided for hot water and steam applications.

    The H3 type features an integrated vacuum valve for the steam cylinder. Maier offers the H Series in many different versions to meet the customers requirements. The new improved and fortified generation of the standard H series is faster and more robust and offers more flexibility, due to a modular system.
