The LATTYsealis mechanical seal is a balanced single mechanical seal available with an optional quench version. It has been specifically developed for challenging applications involving abrasive, scaling, crystallizing, corrosive or solids-laden products such as alumina, phosphates and other mineral-based materials.
Its key feature is a diaphragm incorporating a steel core fully coated with elastomer, providing both chemical protection and excellent resistance to abrasion. Surface treatments can also be applied to product-contact components to further enhance service life.
This simple and robust sealing solution requires neither external flushing nor lubrication. It is easy to install, operates independently of rotation direction and is available in cartridge and quench versions ready for installation. Its design prevents face seizure caused by clogging of a semi-dynamic O-ring.
Secondary sealing materials include HNBR, FKM, EPDM and FFKM. Metallic components are available in stainless steel 304 (1.4301) or 316 (1.4401), with a 316L (1.4404) support and optional chromium carbide coating for enhanced abrasion resistance. Inch-size versions are available upon request.
