Rotary joints are used to transfer fluid to rotating parts. The rotary joints made in JSM machinery are designed for three types of fluids: water, oil and wind, which naturally have different mechanisms of operation (contact JSM consultants for the use of corrosive and chemical fluids). The conventional sizes made for different flow rates are 14, 38, 12, 34 and 1 inch, but JSM Group, having native knowledge of design and manufacturing, has the ability to produce in various other sizes as well.

Long service life, low maintenance and easy installation of JSM rotary joints are its distinctive features because in air type rotary joint, the material of parts is generally selected from high carbon steel and aluminum alloy, and in blue type, due to rust and corrosion, stainless steel brass is used and Also, depending on the application, the type of seals can be selected from PU, PTFE, NBR, Viton, Graphite.
