Kadant Johnson Inc., a subsidiary of Kadant Inc. (Three Rivers, MI), has announced the global launch of a new multi-passage rotary union line for power, fluid and data transfer. The new product line features standard configurations designed to meet the needs of the most common industrial and commercial applications requiring a rotary sealing device with 2 to 12 passages.
Multi-passage rotary unions provide sets of seals between stationary connections and rotating equipment, such as a drum, index table, clutch or spindle. The multiple, independent passages permit the flow of the same or different media into and out of rotating equipment. In most cases, each passage requires isolation from other passages, especially when the different media cannot mix or they operate at different pressures.
The key to reliability is dependable sealing technology, says the company, which is why Kadant Johnson’s multi-passage rotary union line is designed with DuraSeal high-performance elastomeric sealing materials to ensure reliability and long service life for the toughest applications.
