KDAE PISTON SEAL

DESCRIPTION

Amongst the compact piston seal series, the KDAE Piston Seal type is designed with a central polyurethane element and two side anti-extrusion rings. The assembly between the polyurethane element with high elastic modulus and the two elastomer rings with high hardness enhances stability of the sealing even at heavy duty applications. Compared to rubber, the abrasion is also reduced due to the use of polyurethane, therefore extending the service life of the seal in the system. Abrasion is also considerably reduced, thus facilitating the construction of the seat and bores, due to the special geometry of the seal itself better performing than NBR.

TECHNICAL DATA

Pressure: from 0 to 400 bar

Speed: <0.8 m/s

Temperature: from –30°C to +100°C with peaks up to +110°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 (C0) – the backup rings in TPE elastomer 63 Shore D (L2). Compound reference: CR

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. Recommended to grease the piston to facilitate mounting.
