Deublin Bearingless Technology Conventional unions are dependent on bearings for support and smooth low torque rotation. However, bearings inherently have limitations, one of which is premature failure as a result of side loading from piping connections. Deublin has adapted this bearingless technology to CCM applications with proven in-the-field success. Call our Engineering Department for complete details and specifications.

INSTALLATION INSTRUCTIONS PROPER MOUNTING ENSURES LONGER UNION LIFE Flexible hose must be used to connect the rotating union to its supply and return lines. Flexible hose ensures less side load and wear on the bearing surfaces of the union. Rigid piping should not be used. The hose should connect directly to the union, if possible, by way of a live swivel that will eliminate any torsional stress from the pressurized hose. The table shows minimum recommended lengths for the different hose diameters to provide flexible installation. Snap Ring Adapter Lugs Water Supply Pipe Water Flow Areas...
