The 600 Series Multi-Passage Rotary Union features multiple independent flow passages within a single rotating union, enabling the simultaneous transfer of multiple media circuits. Designed for high-pressure industrial applications, it ensures reliable sealing, efficient fluid transfer, and optimum performance in complex rotating machinery.
The 600 Series Multi-Passage Rotary Union features multiple independent flow passages within a single rotating union, enabling the simultaneous transfer of multiple media circuits. Designed for high-pressure industrial applications, it ensures reliable sealing, efficient fluid transfer, and optimum performance in complex rotating machinery.
The 600 Series combines individually separated flow paths with a sealing and bearing arrangement built for stable, reliable operation across every passage simultaneously.
Individual flow paths provide reliable separation and transfer of multiple media.
Self-supported sealing design provides reliable sealing performance during operation.
Dynamic elastomeric sealing provides effective sealing for continuous rotary operation.
Hardened sealing rotor provides improved wear resistance and longer service life.
Widely spaced ball bearings help absorb side loads and provide stable operation.
Each passage stays sealed and independent, while widely spaced ball bearings keep the rotor stable under the side loads a multi-passage union experiences.
Individual flow paths provide reliable separation and transfer of multiple media, so circuits carrying different fluids or pressures never mix within the union body.
Self-supported sealing design provides reliable sealing performance during operation, with dynamic elastomeric sealing providing effective sealing for continuous rotary duty, backed by a hardened sealing rotor for improved wear resistance and longer service life.
Widely spaced ball bearings help absorb side loads and provide stable operation, keeping every passage aligned and sealed even under off-axis mechanical load.
