Flender is increasing the portfolio of its flexible coupling series N-Eupex by introducing three new types. pressure gauge allow customers additional flexibility in their techniques with out shedding the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides even more

safety in the drivetrain in lots of functions. The coupling variant allows users to

specify a most torque so that crucial torques for the motor and output machine

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

injury, thus considerably growing 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 end is linked to the coupling hub through a clamping

connection and not utilizing a feather key and repair capability is elevated. For instance,
assembly or replacement of worn elastomers could be carried out far more easily.
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 launched as a “short

version” into Flender’s modular system. While pressure gauge 10 bar , which was launched in

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

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

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

to the previously used rubber elements made of NBR, Flender now additionally offers

elastomers made from thermoplastic polyurethane (TPU). Following ไดอะแฟรม ซีล for all N-Eupex couplings with NBR packings in 2020, using TPU

packings permits the facility density to be elevated by one other 20 percent on

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

fabric inserts and the torque capability is again raised.
“With a view to the lengthy tradition of cam couplings, our growth engineers are

systematically working on growing the number of combinations even further. The

2022 enhancements give our users a variety of sustainable options for

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

explains André Artmann, Head of Coupling Sales.
