PLT High-Performance Piston 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
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. Following from these parameters is wear, extrusion etc. Our materials are low friction and wear resistant. When applying the right surface parameters in combination with seal type and materials, we are able to supply a very wear and extrusion resistant sealing system for almost all applications.
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.
PLT is a single working piston seal with anti-tilt function. The anti-tilt function makes the back pumping effect worse. The anti-tilt function is applied to prevent the seal from tilting in its groove with high speeds in combination with back pressure. It is only used in hydraulic systems. It can also be used in other fluids. It can be used in tandem systems as a primary seal but with higher velocities it needs a pressure relieve channel in between the seals.
Max. Velocity is 5 m/s also depending on the material used and the medium it is working in.
