  1. Choose The Right Flexible Rubber Bellows for Pumps

  2. Introduction Flexible rubber bellows or expansion joints are an essential component of industrial equipment found in nearly every industry. These flexible rubber bellows are used to protect the rod, piston, or other moving elements from frictional damage, contamination, and/or danger. Given the importance of the part and the application requirements, selecting the proper material and design for the expansion joint bellows is critical. This selection guide provides a few guidelines for selecting the best flexible rubber bellows for your application.

  3. Tips for Selecting Flexible Rubber Bellows When selecting bellows or expansion joints for your machine, consider their exposure to temperature, friction, chemicals, and so on. The following are the steps to take when selecting rubber bellows.

  4. Examine The Surrounding Environment The bellows is covering moving parts that may be exposed to high temperatures, oil, chemicals, or other environmental factors that will necessitate material or part design changes. Make a list of everything that could have an impact on performance or cause failure.

  5. Recognize Joint Movement Joint movement causes friction, heat generation, and wear and tear. The flexible rubber bellows are mounted to reduce the system's impact from these factors. Understanding these forces will assist you in ensuring that the bellows meet your requirements.

  6. Take into account Sealing Requirements As bellows expand and contract, they can trap air and balloon out, or create a vacuum and suck down on the shaft if a closed system is created. To avoid these problems, it is often necessary to create an air exchange in the system. It may be as simple as incorporating an air admittance tube into the assembly.

  7. Consider Attachment Requirements How will the bellows be attached on both ends? Reduce the difference in the type and size of the ends to help control costs. Ends can be as simple as a smooth cuff or as complex as a custom flange tapped with mounting holes.

  8. Outside Dimension Requirements It's easy to forget that your ideal part has to fit inside your footprint, especially if you have a high expansion ratio requirement. The greater the difference in length between the minimum and maximum, the greater the OD of the bellows.

  9. In addition to following the guidelines outlined above, you should purchase your flexible rubber bellows, sleeves, and boots from a reputable manufacturer such as Crushproof Tubing. For almost any application, the company provides high-quality expansion joints, rubber sleeves, and boots. Reference: shorturl.at/hX129
