PD double working piston seal

Seals in particular are 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.

PD is a double working piston seal. It is one of the most commonly used piston seals with low friction and good wear resistance because of good lubrication. It is normally used in hydraulic systems. It can also be used in other fluids and when the wright compound is chosen, it can be used in pneumatics as well. It normally works at its own or together with a single acting seal to make a redundancy.

Max. Velocity is 15 m/s also depending on the material used and the medium it is working in.
