Hydrodynamic Seals

Hydrodynamic seals withstand a wide range of speeds, temperatures and pressures and offer an industry-leading maintenance cycle of more than 20,000 hours.

Technetics’ Hydrodynamic (HD) seals increase the life and performance of propulsion engines, APU’s, gearboxes, generators, pumps and other critical systems and components, especially at high altitudes. Technetics’ revolutionary Advanced Spiral Groove design, in-house manufacturing and testing process have advanced the performance of HD seals beyond industry expectations and standards. Technetics’ unique hydrodynamic code allows for improved modeling and management of coning and accurate prediction of performance at high altitudes.

Made using various high-quality carbon grades, bronze and ceramics, HD seals are available in sizes ranging from 1 to 6 inches in diameter and can be used with both gasses and vapors or mist.

Stringently tested for vibration and oil leakage at altitudes ranging from sea level to 40,000 feet, Technetics’ Hydrodynamic seals are FAA approved and have demonstrated unprecedented performance, reduced maintenance, and increased operational efficiency over competitive products.
