Couplings Type

Couplings for pumps usually fall in the category of general-purpose couplings. General purpose couplings are standardized and are less sophisticated in design. The cost of such coupling is also on the lower side. In addition, there are special purpose couplings that can be used on turbo machines and are covered by the API 671 specification.

In these couplings, the flexible element can be easily inspected and replaced. The
alignment demands are not very stringent. The couplings fitted on pumps usually fall inany of the five types mentioned below.
These are:
1. Gear coupling
2. Grid coupling
3. Disk coupling
4. Elastomeric compression type
5. Elastomeric shear type.
