ไดอะแฟรม ซีล is increasing the portfolio of its versatile coupling series N-Eupex by introducing three new sorts. The new merchandise permit customers additional flexibility in their systems with out shedding the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which offers even more

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

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

are not transmitted. Machines and techniques are shielded from overload and

harm, thus significantly rising 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 connected to the coupling hub via a clamping

connection without a feather key and repair capacity is elevated. For instance,
assembly or substitute of worn elastomers can be carried out rather more simply.
No connecting machine components must be moved, the time required is halved

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

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

2020, addresses the pump market with normal enlargement pieces for normed shaft

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

dimension with out shedding some great benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition

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

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

increase for all N-Eupex couplings with NBR packings in 2020, the usage of TPU

packings allows the facility density to be elevated by one other 20 % on

average. For sizes 300 and above, the acquainted NBR elastomer is combined with

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

systematically working on growing the variety 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 upkeep,”

explains André Artmann, Head of Coupling Sales.
