Flender is expanding the portfolio of its versatile coupling collection N-Eupex by introducing three new varieties. The new products allow customers extra flexibility of their techniques without shedding the compact design and high load capability of a pin coupling.
diaphragm seal -Eupex ERN is supplied with a torque limiter, which supplies even more

security within the drivetrain in plenty of functions. The coupling variant allows customers to

specify a most torque in order that critical torques for the motor and output machine

aren’t transmitted. Machines and methods are protected from overload and

harm, thus significantly growing system availability.
With the N-Eupex B plus clamping factor, 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 via a clamping

connection with no feather key and repair capability is elevated. For instance,
assembly or replacement of worn elastomers can be carried out rather more simply.
No connecting machine components have to be moved, the time required is halved

and so is the downtime of the machine.
With diaphragm seal -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 commonplace growth pieces for normed shaft

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

dimension with out shedding the benefits of a double-cardanic coupling connection.

to the beforehand used rubber elements made from NBR, Flender now also offers

elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque

enhance for all N-Eupex couplings with NBR packings in 2020, using TPU

packings allows the ability density to be increased by one other 20 p.c on

average. For sizes 300 and above, the familiar NBR elastomer is mixed with

material inserts and the torque capability is once more raised.
“With a view to the lengthy custom of cam couplings, our growth engineers are

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

2022 enhancements give our customers a broad range of sustainable options for

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

explains André Artmann, Head of Coupling Sales.
