KDSP PISTON SEAL
DESCRIPTION
The KDSP Piston Seal is designed to be a piston seal with interchangeable seats ISO 6547. It consists of only three elements: a polyurethane seal at the centre and two side wiper rings in glass-filled polyacetal resin. This system does away with anti-extrusion supports, given the high modulus of elasticity of the central element and the higher hardness when compared to nitrilic rubber. Abrasion is also considerably reduced, thus facilitating the construction of the seat and bores and therefore extending the service life of the seal.
TECHNICAL DATA
Pressure: from 0 to 300 Bar with peaks up to 400 Bar at 60°C.
Speed: 0.8 m/s
Temperature: from –30°C to +100°C
Fluids: mineral oils
MATERIAL
The materials used for the construction of this seal type are as follows:
- Polyurethane for the central element, hardness 93 Sh A, compound reference C0
- Glass-filled polyacetal resin (POM) for the side elements Compound reference: CX
ASSEMBLY
This seal can be assembled both in closed groove on a monobloc piston and in open groove on a two-part piston. The piston must not have machining scores which might damage the sealing during the installation.
