The document provides detailed technical specifications for multi-passages rotary unions, specifically the JR series. These rotary unions are compatible with venturi vacuum pumps and can handle all types of fluids. They are designed with a patented principle where rotating parts do not contact each other, allowing for high-speed operation without friction or overheating, eliminating the need for lubrication.

The rotary unions are equipped with electrical slip rings, offering a range of possible electrical circuits (6, 12, 18, or 24) with a maximum intensity of 2 Amps per circuit. They are available in various configurations with different numbers of fluid passages (2, 4, 6, or 8) and passage diameters (4 or 6 mm).

The body of the rotary unions is made from anodized aluminum, ensuring durability and resistance to environmental factors.

The document lists existing versions of the JR series, including JR 2-2, JR 4-4, JR 6-6, and JR 8-8, each with specific configurations and capabilities.
