7300 Series Multi-Passage Flange-Mounted Rotary Unions

7300 Series Multi-Passage Flange-Mounted Rotary Unions

Talco’s new 7300 series has improved upon and replaced our 7200 series Multi-Passage Flange Mounted Unions, also known as Multi-Passage Flange Mounted Rotary Joints.
These multi-passage, flange-mounted unions are designed for extremely high hydraulic pressures while running at moderate RPM’s. We offer you a design that incorporates    Two Deep Groove ball bearings and our unique “Advanced Compound Sealing Technology”  slipper seal design that provides you with a product that has a longer life, lower torque and better performance than standard “O”-ring loaded slipper seals. 

All of the units within the 7300 series will provide an even loading of the entire seal interface area, tremendously high extrusion resistance, hardened and ground shaft and an ultra hard low friction surface.  All models are available with NPT, BSP, SAE or Metric Threads. And Stocked in Aluminum or Steel Housings.  If you prefer, all stainless steel construction is available upon request for superior corrosion resistance, and we do stock
a variety of these ready to ship or we can modify these units to your exact requirements.  

All units are CAD and RFQ Interfaced enabled.  If the models listed do not meet your needs, please contact our experienced and knowledgeable sales staff and they will be happy to help you find a Rotary Union to meet your requirements.
