Flender is expanding the portfolio of its flexible coupling sequence N-Eupex by introducing three new types. The new products allow customers additional flexibility of their systems with out dropping the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which supplies even more

security in the drivetrain in lots of purposes. The coupling variant permits customers to

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

are not transmitted. Machines and systems are protected against overload and

damage, thus considerably increasing system availability.
With the N-Eupex B plus clamping component, Flender introduces a second new

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

plain, cylindrical machine shaft finish is related to the coupling hub through a clamping

connection without a feather key and service ability is increased. For example,
meeting or replacement of worn elastomers may be carried out rather more easily.
No connecting machine components should be moved, the time required is halved

and so is the downtime of the machine.
With digital pressure gauge -Eupex DKS, a model new double-cardanic coupling is introduced as a “short

version” into Flender’s modular system. While ไดอะแฟรม , which was launched in

2020, addresses the pump market with normal expansion items for normed shaft

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

dimension without losing the advantages of a double-cardanic coupling connection.
ไดอะแฟรม for the pin couplings round off the modular extensions. In addition

to the beforehand used rubber components made of NBR, Flender now additionally offers

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

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

packings permits the power density to be increased by one other 20 % on

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

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

systematically working on increasing the number of combinations even additional. The

2022 enhancements give our users a variety of sustainable options for

optimizing their machines and techniques much more and lowering maintenance,”

explains André Artmann, Head of Coupling Sales.
