The GUMMI A-80/90 flexible coupling with ES 250 spacer is a power transmission component that connects two shafts and absorbs misalignment, vibration and torque peaks. The 250 mm spacer allows the elastic element or the pump to be removed without moving the motor or the piping, which is key in back-pull-out equipment. MR Accesorios Industriales carries this brand in Buenos Aires, Argentina, with technical advice to choose the correct configuration.

This item is a flexible coupling from GUMMI's Type A series, model A-80/90, in with spacer (ES) configuration of 250 mm. The spacer is a distance piece inserted between the two hubs so that the assembly has additional length. That free space allows the elastic element, the discs or the rotating part to be removed without axially moving either of the connected machines. It is used in centrifugal pumps, compressors, blowers and other equipment where maintenance is performed on the pump side.

Typical applications are back-pull-out pumps, where the rotor and casing are removed toward the rear without touching the motor or the piping. It is also used in equipment with limited space for dismantling, in installations where the motor is fixed to the base and alignment is not to be corrected after each intervention. In process plants, water treatment, HVAC and pumping systems in general, this type of coupling with spacer simplifies maintenance shutdowns.

To select the coupling, take into account the nominal torque and starting peaks, the rotation speed, the shaft diameter and the type of connection (keyway, flange, etc.). The ES 250 configuration defines the distance between shaft ends: verify that it matches the clearance available on your base. Initial alignment is critical: although the elastic element absorbs misalignment, a misaligned installation shortens the service life of the bearings and of the coupling itself. Follow the manufacturer's instructions for tightening and alignment.
