N-Flex couplings consists of graded cast iron hubs and set of “H” shaped highly resilient blocks which accommodates parallel, angular and axial misalignment & absorbs torsional vibrations. N-Flex spacer couplings / Tyep –RNS ) are suitable for “back Pullout Pumps”in which the impeller can be disassembled without disturbing motor and pump from the base frame.

FEATURES

SIMPLICITY OF CONSTRUCTION

Easy to assemble & disassemble. Suitable for reversing operation.

VARYING STIFFNESS CHARACTERISTICS

Special H shaped inserts provide progressively increasing stiffness characteristics, hence ensure effective shocks & vibration absorption. Special elastomer can be supplied to suit specific application needs.

NO LUBRICATION

RN/RNS couplings do not require lubrication of any kind.

SIMPLE / EASY MAINTENANCE

No complicate mechanism to demand adjustment or maintenance, inspection and replacement of insertsis easy.

LOW OPERATIONAL COST

Only wear part is low cost inserts which make coupling economical in long run.

SMOOTH & QUIET OPERATION

Reduces vibration & noise arising from severe torque fluctuation. Operating temp is -30°C to +100°C
