Multi-Passage Soft-Seal Rotating Unions : engineered solutions

A new product line of multi-passage soft-seal rotating unions is now available from Deublin Company. Rotating unions are components in a broad range of equipment applications that require connection between stationary supply lines, and rotating equipment including cylinders, rolls, spindles and clutches.

While rotating unions are used to convey virtually all types of liquid or gas (steam, water, coolant, hydraulic or cutting fluids, inert gas or vacuum), multi-passage rotating unions are used when more than one media must be conveyed simultaneously using different passages. Soft-seal refers to the Plastomeric seal technology, which is a combination of plastic and elastomer, with a proprietary chemistry and geometry that differs by application.

Applications for Deublin multi-passage soft-seal unions include machine tools, ladle turrets used in steel continuous casting, and metal coil winding, plastic and rubber manufacturing, and more.

Deublin offers standard, semi-custom, and custom options depending on the requirements of each application. Standard features include 2-8 passages, while custom passages for the largest applications can be 22 or more. Port types include NPT, BSP, or SAE.

Rotating Unions and Rotary Joints (also known as rotary swivels, rotary couplings) are precision mechanical devices used to transfer fluid from a stationary source, such as a supply pipe, into a rotating piece of machinery. Rotating Unions and Rotary Joints are used in numerous manufacturing processes to cool, heat, or transfer fluid (pneumatic or hydraulic) power.

Deublin offers (single flow) passage rotary joints, two (dual flow) passage rotary unions, three (triple) passag rotary unions and four passage rotary unions.

Rotary Joints and Rotary Unions allow the feed through of water, glycol, air, hydraulic, coolant, MQL, hot oil, steam, vacuum and a variety of other media. Rotary Joints and Rotary Unions that can be configured for installation at the end of a shaft or around-the-shaft.

Deublin has earned a worldwide reputation for engineering excellence. Owner of numerous patents, Deublin innovations include All-Media, AutoSense™, Pop-Off™ and Controlled leakage unions, high-pressure and hydrostatic unions, and electrical slip rings for both power and signal transmission. Deublin works closely with machine and equipment builders worldwide to deliver engineered solutions to complex component performance requirements.
