DR1-D

Seal designed in accordance with DIN 24960/EN12756, which can be used in a wide range of applications, particularly where fluids are not particularly viscous or prone to solidification. Used when the barrier fluid chamber is present in the device. In the DR1-HD version, the seal being balanced can withstand differential pressure values of 40 bar. For extreme applications, however, specific variations to the stated standards can be supplied.

The seal has undergone continuous evolution over time, enhancing its robustness and reliability. In particular, the torque drive on the rotary seal has been improved, which is in most cases in the Integral configuration.
In contrast to single-spring seals, multi-spring seals have a greater stress response and a more even load distribution.
∆P = pressure of the fluid to be contained - pressure of the barrier fluid.
