The Type 2021 mechanical seal is specifically designed for moderate pressure and temperature applications. It is commonly employed in pumps used for handling water, oils, and other non-aggressive fluids. The design of this seal typically incorporates a flat or slightly curved face, which allows for a uniform distribution of pressure and minimizes wear over time. The sealing faces are usually made from durable materials such as carbon, ceramic, or tungsten carbide, ensuring they withstand varying operational conditions.
