Rotary unions
A rotary union is a mechanical element which ensures the seal between a fixed pipe and a rotaring part, which allows the entry and/or if necessary the exit of air or a fluid ( oil, exchange fluid thermal) of a rotating part.
Rotary union can be made by incorporating a dynamic seal, especially when it comes to fluid transfer, with high rotational speed and/or high pressures.
Simple version of a rotary union, one way is existing. Fluids. The liquid circulates in a one-way passageway.
This model allows liquid to circulate in a two way road. 2 ways are available to allow the liquid to enter the swivel then exist throug another channel.

Sectors
Our rotary unions can be used in the food industry. They are mounted on bottling machines. They can be used for the transfer of cleaning solutions, filling (food contact) or for air transfer.
The rotary union can be used for wastewater treatment ; it allows fixed elements to be connected to moving parts. (wastewater treatment plants for example)
Rotary unions are used to ensure the passage of a liquid which serves to regulate the temperature of a rotating part of a machine. In the plastics and steel industries, they are used in rotary molds.
Rotary unions can be used in machine tools. They deliver oil to lubricate spindles, and cutting oil to tools during machining.
