Operating range

Shaft diameter:
d1 = 20 ... 500 mm (0.79" ... 19.69")
Pressure:
p1 = vacuum ... 250 bar (... 3,625 PSI)*,
p3 = p1 +10 %
Temperature:
t1 = -40 °C... +200 (350**) °C
(-40 °F ... +392 (662**) °F)
Sliding velocity:
vg = 0 ... 5 m/s (0 ... 16 ft/s)

* Depending on size, from 100 ... 150 bar (1,450 ... 2,175 PSI) executed as tandem seal (pressure reduction in 2 stages).
** with cooling flange

! It should be noted that the extremal values of each operating parameter cannot be applied at the same time because of their interaction.

Materials

Seal faces: Carbon graphite
Seats: Silicon carbide, FDA conform
Secondary seals and metallic parts acc. to application and customers' requirement.
