Aston KHD Type
The Aston Seals KHD is a double acting piston seal for high pressure operation and is composed of:
-
A dynamic seal element which assures exceptional low friction and high speed performance, high compatibility with nearly all media due to the chemical resistance which exceeds that of all other thermoplastics and elastomers.
-
A rubber element with low permanent deformation as energizing component on the static side.
-
Two backup rings which offset large gaps or structural deflections without extrusion and assure high longevity.
• Low static and dynamic friction
• No tendency of stick-slip
• Space-saving construction and simple groove design
• High resistance against extrusion
• Extended service life
