Simmerring B2PT

Product catalog summary

Product Description: The Simmerring B2PT is designed for extreme thermal and chemical loads, dry running, and insufficient lubrication, ensuring stick-slip-free behavior. It features a stainless steel metal housing and a PTFE sealing lip.

Product Advantages: This product is suitable for applications in general mechanical engineering and the chemical industry, offering high temperature and chemical resistance, and is effective for dry running and insufficient lubrication. It is particularly useful where stick/slip-free behavior is required, although it has limited dynamic sealing capabilities.

Product Properties: The Simmerring B2PT includes a metal housing, a PTFE sealing lip, and is used in rotary joints, mixers, pumps, and centrifuges.

Material: The metal housing is made from stainless steel (material No. 1.4571), the sealing lip is carbon-filled PTFE 10/F56101, and it includes a fluoro elastomer O-ring.

Operating Conditions: Suitable for use with mineral oils, synthetic oils, greases, water, acids, alkalis, solvents, and gases. It operates effectively within a temperature range of -80 to +200 °C, a speed of ≤30 m/s, and a pressure of ≤1 MPa. Maximum permissible values depend on other operating conditions.

Fitting & Installation: Requires careful fitting according to DIN 3760. Tolerance for the housing bore is ISO h 11, with specific roughness and hardness requirements. The shaft dimensions range from 10 to 125 mm.
