Abstract
A filtration cartridge of a cartridge-based filtration system is provided that includes annular ring arrangements on one or more end caps and the shell of the filtration cartridge. Once engaged, the annular ring arrangements form a coefficient of friction between the end cap(s) and the shell to create a substantially water-tight seal between the end cap(s) and the shell of the filtration cartridge. Annular locking arrangements may be included in addition to, or in lieu of, the annular ring arrangements to lock the end cap(s) to the shell when the filtration cartridge is utilized in high-pressure applications.
Claims20
A filtration system, comprising:
- at least one filtration cartridge;
- and
- at least one housing encapsulating the at least one filtration cartridge, wherein the at least one filtration cartridge includes,
- a lid having a first annular ring arrangement;
- and
- a shell having a second annular ring arrangement, wherein the first and second annular ring arrangements engage each other to seal the lid to the shell.
A method of assembling a filtration cartridge, comprising:
- providing an annular ring arrangement on a lid of the filtration cartridge;
- providing an annular ring arrangement on a shell of the filtration cartridge;
- and
- engaging the annular ring arrangements of the lid and shell to seal the lid to the shell.
A filtration system, comprising:
- at least one filtration cartridge;
- and
- at least one housing encapsulating the at least one filtration cartridge, wherein the at least one filtration cartridge includes,
- a lid having a first annular ring arrangement and a first annular locking arrangement;
- and
- a shell having a second annular ring arrangement and a second locking arrangement, wherein the first and second annular ring arrangements engage each other to seal the lid to the shell and the first and second annular locking arrangements engage each other to lock the lid to the shell.
