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.
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.
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
