Sf Dynamic Ring Series

The Sf dynamic ring series (C-type stepped pressureless silicon carbide sealing ring) is a cost-effective dynamic ring for C-type (stepped) pressureless silicon carbide sealing rings, a high-pressure pump sealing and reaction vessel sealing component resistant to high and low temperatures. The Sf series is made of pressureless sintered silicon carbide, retaining the classic characteristics of high hardness, excellent wear resistance and thermal conductivity of the material. At the same time, performance and cost have been balanced through mature processes. Its C-shaped step structure enhances the fit of the sealing surface, forming a multi-layer sealing barrier, which is suitable for the complex working conditions of high-pressure pumps and reaction vessels, and can control procurement costs while ensuring operational reliability. This series is the preferred choice among high and low temperature resistant seals that balances performance and economy, and is widely applicable to various…
