GBC Couplings

Couplings are use to joint of pumping system and the pump driver. Pump with high load need a high power should use a good perform coupling. Pump system should align all together and should be test by maintenance people. Design of GBC coupling has been optimized in order the power capacities balanced to the appropriate shaft diameter.

Load on the coupling to move the part like pump impeller can reduce by a flexible element, the deflection of which is a prime design consideration. Transient peak load also can reduce by this element.

Misalignment incidentally on the parallel angular and axial displacement of the connected shafts can be accommodated. Taper Bushes are fitted to the complete standard coupling range, bored to size flanges also available.

Selection using this kind of coupling is may either of two ways:
  1. Where the prime mover is an electric motor and demand power or demand torque unknown, select the coupling using data from couple tables.
  2. Where the driven machine demand power (or torque) and operating duty are known, select the coupling using the following procedure.

    • Service Factor
    • Design Power
    • Coupling Size
    • Bore Size
