 NUTECH D2 ASSEMBLY SEAL

Features and Benefits

  • Stop clogging problems that plague multiple spring loaded seals. Suspended particles are thrown away from the bellows convolutions by centrifugal force.

  • Another advantage of this seal is it's inherent pressure balanced design, being able to withstand pressures up to 300 psi and down to vacuum without using costly stepped shafts or sleeves.

  • Effective 360° contact is maintained on sealing faces despite minor shaft movement and runout.

  • Vibration dampening design helps control excessive vibration which can cause either improper face/seat seating or fatigue failure resulting in excessive seal leakage.
