FLENDER COUPLINGS N-EUPEX 3103en, Assembly And Operating Instructions Manual, Page: 17 / 64

Description
3
The N‑EUPEX couplings described here are torsionally flexible, damping pin couplings and are
available in various types and sizes. The couplings can be used in accordance with the ATEX
Directive in potentially explosive atmospheres if they have a CE marking.
Types O and P are fail-safe. Types O and P are designs that feature a brake drum (coupling part
32).
These instructions describe the assembly and operation of an N‑EUPEX coupling arranged
horizontally with a shaft-hub connection made by a cylindrical or conical bore with parallel key.
Please consult Flender if you want to use a different type of installation.
Application
N‑EUPEX couplings are designed for use in all kinds of machines.
