Centrifugal pressure seals are components that prevent leakage, contain pressure, and prevent contamination by harnessing rotational forces. Unlike mechanical contact seals, which rely on two mated components in direct contact, a centrifugal pressure seal uses a non-contact, frictionless design. These seals create a pressure differential – where the pressure inside the seal is greater than the pressure outside the seal housing – to improve performance.
Centritec Seals’ patented solutions help extend lifecycles, improve energy efficiency and minimize downtime - providing a proven, easy-to-install rotating seal solution for a wide variety of applications.
Centritec Seals features a proprietary double-seal design, patented by Carlyle Johnson, that keeps lubricants in and keeps contaminants out. Engineers rely on our unique solution for reliable sealing, flexible axial alignment, and minimal heat generation. These seals are commonly used a cost-effective sealing solution in extreme environments, including turbines, rolling mills, industrial machinery, and wind power generation.
Centritec’s non-contact centrifugal pressure seal design is extremely efficient - operating with minimal parasitic drag even in applications with continuous, high-speed operation. With its rotating chamber sealing method, these components significantly reduce operational speed requirements when compared to typical non-contact seals and can support the use of extremely low viscosity fluids, even as low as water, as lubricant.
Their ability to operate effectively over long lifecycles allows Centritec solutions to succeed in applications where other seals fail. This unique centrifugal pressure non-contact seal design minimizes friction – resulting in lower energy consumption, reduced heat generation, and decreased wear. Unlike many common rotating shaft seal types, our solutions can operate for long periods without maintenance – as demonstrated in a water-to-energy steam boiler shaft sealing application – where Centritec Seals achieved a lifecycle more than 3X longer than the previous non-contact rotary seal solution.
