For rotating equipment where the drive has to come out without disturbing the pump casing or the pipework, the GUMMI A-20/25 ES 75 coupling is built for that job. It links two shafts, takes up misalignment, and carries a 75 mm spacer between the hubs. MR Industrial Accessories supplies this reference from the GUMMI Type A line to maintenance and purchasing teams in the United States and Latin America.

Reading the code helps when you compare it against what is on the machine. A-20/25 is the coupling model, and ES 75 tells you a spacer is fitted and that it measures 75 mm. Type A couplings from GUMMI are known for a sturdy build and for fitting a wide range of duties. With the spacer in place, the flexible element or the impeller can come out while the piping stays connected, which shortens the work on equipment that is opened up often.

Centrifugal pumps are the usual home for this coupling, particularly back-pull-out designs where the impeller is drawn out toward the rear and the suction and discharge lines are left alone. Compressors, fans and other rotating machines that need to absorb misalignment and vibration are also common users. Installations with tight space or a maintenance plan built around quick interventions tend to specify the spacer version.

Selection comes down to torque, speed and shaft diameter, and the 75 mm spacer has to line up with the gap between shaft ends. Alignment at assembly matters, since poor alignment puts extra load on the bearings and the flexible element. Type A couplings tolerate some angular and radial offset, but only inside the limits the manufacturer sets.

If you are working from an equivalent or a cross-reference, send the part number or model through WhatsApp or email. The team can point you to the right reference and help you confirm the fit for your application. Couplings sit alongside sheaves, pulleys and chains in what we supply for power transmission.
