Operating range

Shaft diameter:
d1 = 18 … 100 mm (0.625″ … 4″)
Pressure:
p1*) = 0.8 abs…. 25 bar (12 abs. … 363 PSI)
Temperature:
t = -50 °C … +220 °C (-58 °F … +430 °F)
Sliding velocity: vg = 20 m/s (66 ft/s)
Axial movement: ±0.5 mm* An integral stationary seat lock is not needed within the permissible low pressure range. For prolonged operation under vacuum it is necessary to arrange for quenching on the atmospheric side.
