Operating range
Shaft diameter:
d1 = 30 ... 75 mm (1,125" ... 2,625")
(other dimensions on request)
Product pressure:
p1 = max. 22 bar (319 PSI),
(dependent on shaft diameter and sliding materials)
Barrier pressure: p3 = max. 25 bar (362 PSI),
Differential pressure: Δp= min. 3 bar (44 PSI)
Temperature:
t = -20 °C ... +170 °C (-4 °F ... +338 °F)
(dependent on resistance of O-Rings)
Sliding velocity: vg = 16 m/s (52 ft/s),
with special design max. 25 m/s (82 ft/s)
Axial movement: ±0.2 mm
