Designed for steam, water, and thermic fluid applications, it delivers reliable sealing performance, efficient fluid transfer, and long-lasting durability.
The 501 Series combines flow and syphon configuration options with a construction and sealing arrangement built for durability and low maintenance.
Available for different fluid transfer applications.
Suitable for both stationary and rotary syphon applications.
Robust construction for reliable performance and long service life.
Spherical seals allow movement in all directions while maintaining reliable sealing without leakage.
Carbon graphite plain two bush bearings provide greater rigidity, longer life, and less wobble run-out than other comparative products.
Different sealing grades are available according to the application requirements.
The optimized design also minimizes the number of spares required, simplifying maintenance over the joint's service life.
The carbon graphite spherical seal and the widely spaced two-bush bearing arrangement work together to keep the joint sealed and stable across its full operating range.
Carbon graphite spherical seals allow movement in all directions while maintaining reliable sealing without leakage — keeping the joint sealed even as minor misalignment occurs during operation.
Widely spaced carbon graphite plain two bush bearings provide greater rigidity, longer life, and less wobble run-out than other comparative products.
The dense cast steel housing and stainless steel grade working parts give a robust construction for reliable performance and long service life.
Sealing grade and configuration are confirmed against your specific media, pressure, temperature, and speed requirements.
