Features
- Single pusher-type seal
- Unbalanced
- Conical spring
- Dependent on direction of rotation
Advantages
The BT-FH is a seal for demanding applications where operating conditions in the pump require machined metal parts for the mechanical seal. The seals are available in a full range of diameters from 10 to 100 mm and in the standard diameters specifically for chemical applications.
Operating range
Shaft diameter:
d1 = 10 … 100 mm (0.39" … 3.94")
Pressure: p1*= 12 (16) bar (174 (232) PSI)
Temperature:
t* = -35 °C … +200 °C (-31 °F … +392 °F)
Sliding velocity: vg = 15 m/s (49 ft/s)
* Dependent on medium, size and material
