Types of Rubber Bellows Seals
Whether you are looking for a replacement or a new rubber bellows seal for your pump, the following information will help you decide which is the best option. These mechanical seals are available in many sizes and can meet most requirements. Listed below are some of the most common types of bellows seals. All are available in metric and inch sizes, and several international standards are available. The following examples describe some of the features of these bellows seals and the various applications they are used for.
The most common types of Rubber Bellows Seals are available in metric and imperial sizes. If you need a seal that will fit in the common housing sizes and dimensions, you may need a fully split seal. Rubber bellows seals eliminate the need for springs or O-rings, and their narrow profile allows for flexibility of shafts. They are also suitable for both vertical and horizontal installations, and do not require any special equipment modification.
While there are many types of rubber bellows, most manufacturers only manufacture them for specific uses. The two primary types of rubber bellows are flexible connectors and protective seals. Other uses for these bellows include tubing and expansion joints. Their uses depend on how they are made, which can affect the selection process. Some types of bellows are molded with an extended resting position, which means the convolutions are in an extended position. These types of bellows are also available in a convoluted design.
Whether you need a single-acting or double-acting seal, you can count on the expertise of our sealing experts. We have a team of material scientists and engineers who can provide you with professional advice to select the best solution for your specific application. They can help you identify which type of bellows seal is best for your needs and the best way to use them. You can also contact our Sealing Systems Consultancy service for assistance with your project.
If you need a seal to be flexible, a rubber bellows can be the perfect solution. The bellows expand and contract to fit the exact size of the mating part and not compromise the integrity of the seal. Because they are flexible, they can provide secondary sealing and help to reduce vibration between mating parts. They are also effective at absorbing mechanical noise and can also accommodate minor misalignment. They are available in custom and stock options.
Rubber bellows mechanical seals are the most common type of bellows mechanical seals. They feature an auxiliary rubber bellows seal that can compensate for shaft misalignment wear. They have no bonded joints and are highly compatible with any type of seat housing configuration. They are also easy to install and don't require any adjustments to their dimensions. You can choose between graphite packing seals and elastomer seals depending on your specific application.
