Trelleborg Sealing Solutions presented a new seal, Turcon® Roto Glyd Ring® V, which is primarily intended for double-acting pressure within severe working conditions that require extended rotary service. The seal is specifically engineered for machinery where a high pressure to velocity value is required to allow equipment to run at the highest possible speeds in high pressures for an extended service life.
Test results show that Turcon® Roto Glyd Ring® V runs with low frictional torque at all pressures from 0.5 MPa and above with low sensitivity to pressure increases from 0.5 to 20 MPa. It achieved a PV twice as high as other bidirectional seals and demonstrated 50% lower friction. Furthermore, wear of the seal and O-Ring was so low that it could not be measured.
With maximum recommended operating temperatures of +100 °C (up to +150°C at lower PV-values), Turcon® Roto Glyd Ring® V is designed to fit into standard Roto Glyd Ring® grooves. It is available in four cross section series; for shafts in diameters from 35 to 500 millimeters and for bores from 22 to 500 millimeters.
The needed user specification are the following: pressure should be limited to a maximum of 30 MPa, velocity needs to be limited to 2.0 meters per second.
