The GUMMI A-30/35 ES 140 is a flexible coupling from the Type A series that connects shafts while absorbing misalignment, vibration, and shock. Its 140 mm spacer allows the driving equipment to be removed without disturbing the driven machine, which is essential on back-pull-out pumps. MR Industrial Accessories supplies this coupling as part of its power transmission line for maintenance and replacement in industrial plants.

This coupling is identified by the code A-30/35 ES 140: A-30/35 indicates the size within the GUMMI Type A series, while ES 140 specifies the spacer configuration with a 140 mm length. The spacer separates the two hubs, simplifying disassembly of the assembly without moving the connected equipment. As a power transmission component, it mounts between shafts to transmit torque and compensate for angular, radial, and axial misalignment.

Typical applications include back-pull-out centrifugal pumps, where the impeller and casing are removed toward the back without touching the piping or motor. It is also found on compressors, fans, mixers, and other rotating equipment that requires frequent maintenance. The 140 mm spacer provides the clearance needed to remove the flexible element and hubs without repositioning the machine. This makes it common in process plants, water treatment, and pumping systems.

When selecting the coupling, consider shaft diameters, torque to be transmitted, revolutions per minute, and the type of misalignment expected. The Type A series is chosen by size according to nominal torque. During installation, align the shafts precisely before tightening the hubs, and verify parallelism and concentricity. The spacer must be centered and free of tension. Follow the manufacturer's instructions for tightening and lubrication, if applicable.
