Advantages

The BT-PN is a large series mechanical seal with a simple yet effective design that is easy to assemble. The special spring arrangement allows a short axial installation length. This advantage is combined with an increased working pressure capability of up to 12 bar (174 PSI). The spring is free from torque transmission.

Operating range

Shaft diameter:
d1* = 8 … 40 mm (0.31" … 1.57")
Pressure: p1** = 12 bar (174 PSI),
vacuum … 0.5 bar (7.45 PSI)
Temperature:
t** = -20 °C … +120 °C (-4 °F … +248 °F)
Sliding velocity: vg = 10 m/s (33 ft/s)

Operating limits depend on p・vg factor

* Other diameters upon request
** Dependent on medium, size and material
