The GUMMI A-45/50 ES 140 coupling is a flexible power transmission element that links two shafts while tolerating misalignment, vibration and shock. The ES 140 spacer, 140 mm long, sits between the hubs so you can pull the pump or driver without shifting either machine—a common need on back-pull-out pumps. MR supplies this model within the GUMMI Type A coupling range.
This coupling is identified as A-45/50 and comes with an ES spacer measuring 140 mm. That intermediate piece keeps the hubs at a set distance, so the flexible element can be taken out or the shaft separated without moving the connected equipment. The Type A design handles angular and radial misalignment, which helps protect bearings and seals over time.
You will find these couplings on centrifugal pumps, particularly back-pull-out units where the impeller and casing come out toward the rear with the piping still connected. Compressors, fans, mixers and other rotating machines that see regular maintenance also use them. The 140 mm spacer simplifies alignment work and cuts downtime.
When choosing a coupling, check shaft diameters, torque, RPM and the misalignment the machine can accept. During installation, align the hubs carefully before fitting the flexible element and confirm the spacer is centered. Misalignment creates extra loads that reduce the life of both the coupling and the bearings.

Frequently asked questions
- What does ES 140 mean in the coupling part number?
- ES means the coupling includes a spacer, and 140 is its length in millimeters. This setup lets you remove the equipment without moving the machines, which matters on back-pull-out pumps.
- How do I request a different size or an equivalent?
- Send the part number A-45/50 ES 140 on WhatsApp or provide your shaft and machine data. MR helps you find the right variant within the GUMMI Type A line.
- What should I check before mounting the coupling?
- Check shaft alignment, torque and working RPM. The spacer must be centered and free of tension. Precise alignment avoids unnecessary loads and extends the life of the coupling and bearings.
