The GUMMI A-60/70 ES 140 flexible coupling is a power transmission component that connects two shafts and absorbs misalignment, vibration and torque peaks. Its 140 mm spacer configuration allows the flexible element or the driven equipment to be removed without moving the motor or the machine, which is key in back-pull-out centrifugal pumps. MR Accesorios Industriales supplies this GUMMI line in Buenos Aires, Argentina, with technical advice to select the correct size.

This item is a coupling from the GUMMI Type A series, model A-60/70, in a configuration with a 140 mm ES spacer. The spacer is a distance piece inserted between the two hubs that maintains the separation between shafts, so the flexible element works with the correct gap. The A-60/70 model defines the hub size and transmission capacity; the 140 mm spacer sets the distance between the flanges. It is used with flexible elements of the same series to complete the assembly.

Typical applications are process centrifugal pumps, especially back-pull-out types, where the rotor is removed toward the rear without disconnecting the piping. It is also used in fans, blowers, screw compressors and transmission equipment where small misalignments need to be compensated and vibration transmission reduced. The spacer simplifies maintenance: the flexible element is removed and the equipment is released without moving the motor.

To install this coupling, check that the distance between shaft ends matches the 140 mm spacer and that the hubs are aligned within the manufacturer's tolerances. Alignment is checked with a straightedge, dial indicator or laser, depending on the equipment. The flexible element must be free of axial tension and have the recommended clearance. When selecting, take into account the nominal torque, rpm, shaft diameter and type of load. If you need to confirm the combination, send us the equipment data.

If the A-60/70 ES 140 model is not the right one, we can look for a nearby size or an equivalent within the GUMMI Type A line. To do this, send us the original part number, the shaft diameters, the distance between ends and a photo of the coupling. With that data we review the series and offer you the option that best fits. We also work with other brands of flexible and rigid couplings.
