SR2 Low Friction Rod Seal
Seals are particular exposed to pressure, friction and temperature. Our aim is to design and make seals or sealing systems that perform optimal for all these parameters.
Product Description
Below you can find an overview of sealing and bearing materials. Please select the suitable material for your application. When you have any difficulties with selection of a material, contact your AST representative.
Sealing surfaces are very much known for influencing the wear, extrusion and the leakage rate for a sealing system. When applying our sealing systems, please follow our specifications. You will find these specifications through the schedule below.
SR2 is a single working spring activated low friction rod seal. It can be used in almost all media, also in a wide range of chemicals. The spring load makes it statically tide, also when no pressure applied yet. Because no elastomer parts involved it is able to handle temperatures form cryogen to up to 300 degrees Celsius. Please ask your AST representative for suitability in your application.
Max. Velocity is 3 m/s also depending on the material used and the medium it is working in.
