With around 250 locations and 90 serve centers, we are represented in the most important economic regions of the world. The advantages are clear: short paths to our customers, fast response times and a shared language.
Torque transmission by clamping ring for large axial movements
Non-contacting operation
No friction on the seal faces, no heat generated at the seal or in the medium
ATEX certification on request
Operating range
Shaft diameter: d1 = 40 ... 220 mm (1.6" … 8.7")
Pressure: p1 = vacuum ... 6 bar (87 PSI),
Δ p = min. 3 bar (44 PSI), p3 = 9 bar (131 PSI)
Temperature: t1 = -20 °C ... +200 (+250*) °C (-4 °F … +392 (+482*) °F)
Sliding velocity: vg = 0 ... 5 m/s ( 0 ... 16 ft/s), higher velocities on request.
* 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.
