Fluidic Rotary Joints

The fluidic rotary joints distributed by Servotecnica are manufactured, inspected and certified by our American representative DSTI, the ultimate goal is to provide highly reliable components, ensuring the highest quality-cost ratio.  The fluidic joints are also known as: hydraulic rotary joint, pneumatic rotary joint, rotary joint for liquids, rotary joint for air, fluidic manifold.
The main purpose of the fluidic rotary joint is to transfer liquids, fluids or gases, from a fixed structure to a movable one. Fluidic rotary joints consist of two parts: an outer one called STATOR (because it is normally stationary) and an internal one called ROTOR (because it normally rotates), they may feature several passages and the seals are made specifically according to the fluid or gas to be carried. Operation is reversible, i.e. the external part, which is normally fixed, can be made to rotate and, as a result, the internal part (which normally rotates) can be kept fixed.
DSTI offers a wide range of fluidic joints, starting from the simplest manifold of the SPS series with a single passage, aluminium casing and seal up to 40 bar at 500 RPM. Fluidic joints particularly suitable for carrying air or gas are those of the LT series featuring 2-4-8-12 up to 24 passages, with 1/8” or 3/8” connections, pressures up to 40 BAR at 500 RPM, suitable for rotary tables and also for vacuum up to 30 HG. If the gas pressure is very high and the space available is limited, the SE series with 2-4-6-8-12-16-24 passages is the correct solution. It can reach 512 BAR at 300 RPM. For higher speeds up to 500 RPM, 512 BAR pressure, we recommend the GP fluidic joint series featuring 2-3-4-6-8-10-12 passages and connections up to 1”. A special solution is used for GPS mixed fluidic joints made of stainless steel, making it possible to carry both gas and liquid at the same time, thanks to a special technique used for the seals called DynaSeal. To increase the flow rate of gases or liquids, we recommend the rotary joints from the HV series with 3-4-6-8 passages and pressures up to 345 BAR at 50 RPM. Maximum performance is achieved with the HPS series featuring 1-3-4-6-8-12-16 passages, made entirely of stainless steel, which can reach pressures up to 1375 BAR at 50 RPM. For each series there are customised solutions available which can cover all requirements in the field of fluidic rotary joints.
