PSH + RR PISTON SEAL
DESCRIPTION
The PSH piston seal type is similar to the PSA type, but it has an acetylic resin wear ring to mitigate possible misalignments and avoid extrusion. A RR retaining ring made of thermoplastic resin prevents seal extrusion during the cycle inversion.
TECHNICAL DATA
PSH + RR Piston Seal
Pressure: <400 bar at a temperature of 60°C
Speed: <0.5 m/s
Temperature: from -35°C to +100°C with peaks till +110°C
Fluids: mineral fluids and oils
MATERIAL
The proposed material is a C0 -type polyurethane with high modulus of elasticity, low compression-set and high resistance to abrasion. The wear ring is made of a R0 type acetylic resin, and is reinforced with fibreglass. Compound reference PSH: CR
The retaining seal is made of thermoplastic resin, R2 type. Compound reference RR: R2
ASSEMBLY
Avoid all cutting edges and flash on the piston where the seal is housed. A lead-in chamfer in the groove will facilitate the insertion of the piston. Lubricate the seal before installation.
