3 part piston seal
Description
KDSP is a piston seal designed with removable seats according to ISO 6547th
It consists of three parts. 1 polyurethane sealant in the center and two guide rings POM.
The seal does not need back up rings thanks to high elasticity and the PU piece has a higher hardness than nitrile rubber (NBR)
Compared with a rubber seal, wear is substantially less roofs, and therefore the life considerably longer.
The friction both at startup and during operation is low thanks to the seal special design and the preformer much better than example. NBR
Material
Sealing part Polyurethane (PU)
Guide Rings: Glass filled Poluoxymethylen (POM)
Technical data
Press: 0-300bar with peak up to 400bar at 60 ° C
Speed: <0.8 m / s
Temperature: -30 ° C to + 100 ° C
Mounting
The installation of this seal may be in either a closed track (monoblock seal) or an open track (2 shared stamp).
The installation is made in the following order:
- Rubber seal member
- Page support rings
- External support rings
It is important that the piston does not have burrs or other sharp edges which might damage the seal during installation.
