PISTON SEAL DT11

STANDARD SEAL DIMENSIONS

DESCRIPTION

The DT11 seal has a double profile in the 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 at low and high pressure. The shape of the central double profile prevents hydrodynamic pressures on the seal and the resulting blow-out effect.

TECHNICAL DATA

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 98Shore 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 hardness, according to the specific operating pressures.

ASSEMBLING

Cutting edges or flash must be removed in the housing of the seal. Ensure a lead-in chamfer in the bore to facilitate the piston installation.
