Flender is increasing the portfolio of its versatile coupling collection N-Eupex by introducing three new varieties. The new merchandise permit users extra flexibility in their systems with out dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies even more

safety in the drivetrain in many purposes. The coupling variant allows customers to

specify a maximum torque so that critical torques for the motor and output machine

usually are not transmitted. Machines and methods are protected from overload and

harm, thus significantly increasing system availability.
With the N-Eupex B plus clamping element, Flender introduces a second new

coupling that ensures frictionally engaged clamping connections. In this case, the

plain, cylindrical machine shaft end is linked to the coupling hub through a clamping

connection and not using a feather key and service capability is elevated. For instance,
meeting or substitute of worn elastomers may be carried out rather more simply.
No connecting machine elements must be moved, the time required is halved

and so is the downtime of the machine.
With the N-Eupex DKS, a brand new double-cardanic coupling is introduced as a “short

version” into Flender’s modular system. While the DK kind, which was launched in

2020, addresses the pump market with standard growth items for normed shaft

distances, the DKS is the shortest possible double-cardanic resolution for the market.
The shortened general length permits cost-optimized use with a small shaft distance

dimension with out losing the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition

to the previously used rubber elements manufactured from NBR, Flender now additionally offers

elastomers made of thermoplastic polyurethane (TPU). Following the torque

enhance for all N-Eupex couplings with NBR packings in 2020, the use of TPU

packings permits the facility density to be elevated by another 20 p.c on

common. For diaphragm seal and above, the familiar NBR elastomer is mixed with

cloth inserts and the torque capacity is once more raised.
“With a view to the long tradition of cam couplings, our growth engineers are

systematically engaged on increasing the variety of combos even additional. The

2022 enhancements give our users a wide range of sustainable options for

optimizing their machines and techniques even more and decreasing upkeep,”

explains André Artmann, Head of Coupling Sales.
