The XF Mechanical Seal is a heavy-duty component sealing solution designed for industrial pump systems operating under harsh and demanding conditions. With a full tungsten carbide (TC) configuration, it delivers superior durability, high wear resistance, and reliable sealing performance.
Available in multiple sizes (including 20mm, 25mm, and 35mm), this model supports a wide range of pump applications. Its robust structure ensures stable operation, reduced leakage, and extended service life even in abrasive and high-load environments.
Equipped with secondary sealing options such as NBR and VITON, along with stainless steel components, the XF offers excellent resistance to corrosion, temperature variations, and aggressive media, making it ideal for continuous-duty industrial operations.
