PSQ PISTON SEAL
DESCRIPTION
The PSQ Piston Seal has a double-ended profile in the middle, in the dynamic part, and two small steps in the static part where the Q-ring is housed.
The Q-ring energizes the seal and provides a perfect sealing performance both at low and high pressure.
Also the shape of the central double-ended profile prevents hydrodynamic pressures on the seal and the resulting blow-out effect.
TECHNICAL DATA
PSQ Piston Seal
Pressure: <250 Bar with a C0-type material at 93 Shore A, at a temperature of 60°C. < 400 Bar a D0-type material, at 98 Shore A, at a temperature of 60°C.
Speed: <0.8 m/s
Temperature: from –35°C to +100°C with peaks up to 110°C.
Fluids: mineral oils
MATERIAL
The sealing parts are in polyurethanes with different hardnesses, according to the specific operating pressures.
Compound reference: CQ (93 Shore A with Q-ring ) or, alternatively, DQ (98 Shore A with Q-ring)
ASSEMBLY
Cutting edges or flash must be removed in the housing of the seal. Ensure a lead-in chamfer in the bore to facilitate the installation of the piston.
