BT-PN - Product variants
BT-PNL
The small outer diameter of the BT-PNL allows installation in small seal chambers. Easy to assemble, the BT-PNL guarantees a long service life due to good product turbulence and the torque transmitted by the rubber bellows.

BT-PN and PNL double seal
(back-to-back arrangement)
Both types of seal can also be used as a multiple seal in back-to-back arrangement. This is advisable when the product media cannot ensure lubrication or the solids content is too high (oil chamber). Installation proposals can be supplied upon request. In this configuration, the operating pressure (product side seal) must be limited to max. 2 bar (29 PSI).
