The GUMMI A-20/25 ES 100 flexible coupling is a power transmission component that connects shafts and absorbs misalignment, vibration and shock loads. Its configuration with a 100 mm spacer allows the elastic element or the equipment to be removed without moving the machines, which is key in back-pull-out pumps and assemblies where working space is limited. MR Accesorios Industriales sells this GUMMI line in Buenos Aires, Argentina.

This coupling is identified by the model A-20/25 and is supplied with a 100 mm ES spacer. That intermediate piece separates the two hubs enough to remove the flexible element without moving motors or pumps. The designation A-20/25 ES 100 combines the coupling size with the spacer length, a data point that defines the clearance required between shafts. The GUMMI Type A series is a line of general-purpose couplings, with hubs and elastic elements that transmit torque and damp irregularities.

Typical applications of a coupling with a spacer like this appear in back-pull-out centrifugal pumps, where the head rotates and is pulled back without touching the piping or the motor. It is also used in compressors, fans, mixers and conveyors that require frequent maintenance of the elastic element. In all those cases, the 100 mm spacer avoids dismantling the entire line: the coupling is released, the element is slid over and replaced. It is a practical solution for equipment that cannot be out of service for long.

To select this coupling properly, take into account the shaft diameters, the nominal and maximum torque of the drive, and the working revolutions. The 100 mm spacer imposes a distance between shaft ends that must be respected so as not to stress the elastic element. Check angular and radial alignment before tightening the hubs, and use the fastening screws at the torque recommended by the manufacturer. If the equipment has rotation reversal or pulsating loads, consult the technical area to validate the model.

If you need a coupling with a different spacer length, a model from the Type A series or a different hub size, write to us on WhatsApp with the code or model you are looking for. We can also guide you if you have to replace an existing coupling and cannot find the identification. At MR Accesorios Industriales we work with the GUMMI line and we will give you a reply shortly so you can request a quote for the part you need.

To move forward with the quote, send us the code A-20/25 ES 100 or the complete designation of the coupling shown on the equipment plate. If you already have the assembly put together, a photo of the flange and the distance between shafts helps confirm the variant. Our sales team in Buenos Aires, Argentina, will reply to you on WhatsApp shortly with the options that apply to your application.
