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 flexible 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 supplies this brand in Buenos Aires, Argentina, with technical advice to choose the right configuration.

This item is a flexible coupling from the GUMMI 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 clearance allows the flexible 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 done from the pump side.

Typical applications are back-pull-out pumps, where the rotor and casing are pulled back without touching the motor or the piping. It is also used in equipment with limited space for disassembly, in installations where the motor is fixed to the baseplate and alignment is not to be corrected after every 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 diameters and the type of connection (keyway, flange, etc.). The ES 250 configuration defines the distance between shaft ends: check that it matches the clearance available on your baseplate. Initial alignment is critical: although the flexible 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.
