Pneumohydraulic rotating unions have very high sealing requirements, and different designs and sealing materials are required depending on the type of medium and pressure used.
Jinpei has entered into a co-operation agreement with a well-known German pneumohydraulic rotary seal manufacturer to jointly develop pneumohydraulic rotating unions.
According to the different needs of various customers, conductive slip rings, high-frequency swivel joints, waveguide swivel joints and fibre optic swivel joints can be integrated into pneumohydraulic swivel joints.
High-precision part processing combined with advanced surface treatment technology and new testing equipment ensure the surface precision and wear resistance of the rotary shaft; the design and original imported seals, which have been strictly selected by a panel of experts, fully guarantee the stable and excellent performance of the products in various media (compressed gas, hydraulic oil, liquid, paint and other fluids) and working pressure.
