The T1 is a versatile and robust machined mechanical seal designed for high-performance industrial applications. It serves as a direct replacement for the JOHN CRANE 1 (US) and AESSEAL P05U models. Engineered for reliability, we offer flexible material combinations to match your specific needs, including Carbon, Ceramic, and Silicon Carbide. Furthermore, we provide full customization and design services to create bespoke mechanical seals that meet unique client requirements.
Versatile Material Combinations: Available in Carbon/Ceramic, Resin Carbon/Ceramic, SiC/SiC, and TC/TC faces.
High Pressure Resistance: Designed to handle operating pressures up to 2.8MPa.
Advanced Secondary Seals: Includes O-rings made from NBR, EPDM, or VITON for chemical compatibility.
Broad Temperature Range: Reliable operation in environments ranging from -30°C to +200°C.
Precision Engineering: Stationary rings available in Ceramic, SiC, TC, or SUS304 for maximum durability.
High Speed Capability: Optimized for rotational speeds reaching up to 13 m/s.
