The GUMMI A-20/25 ES 140 flexible coupling is a power transmission component that connects the motor shaft to the machine shaft, absorbing misalignment and vibration. Its configuration with a 140 mm spacer allows the flexible element or the pump to be removed without moving the motor or the piping, ideal for back-pull-out equipment. MR Accesorios Industriales supplies this GUMMI reference for industrial applications that demand operating continuity and simple maintenance.

This GUMMI coupling corresponds to model A-20/25 in spacer (ES) configuration of 140 mm. The spacer is an intermediate piece that separates the two hubs and provides access to the flexible element, so it can be replaced without axially moving the equipment. The GUMMI Type A series is characterized by its robust construction and its ability to compensate angular and radial misalignment, which extends the service life of bearings and seals.

Typical applications for this coupling with a spacer are back-pull-out centrifugal pumps, where the pump casing is pulled back without disconnecting the motor or the piping. It is also used in compressors, fans, mixers and other rotating machines that require frequent maintenance of the flexible element. In process plants, water treatment or the food industry, this design reduces downtime and simplifies replacement tasks.

To select the coupling correctly, take into account the nominal and maximum torque of the application, the rotation speed, the shaft diameters and the type of load. The ES 140 spacer configuration requires checking the distance between shaft ends so that the spacer fits without forcing. Mounting must align the hubs precisely, using feeler gauges or a dial indicator, and tighten the screws to the torque recommended by the manufacturer.
