Abstract
In a bellows pump, detecting any leakage with respect to the bellows can be important, for example for pump durability and life. Disclosed embodiments relate to a bellows pump system in which the bellows is configured to form an annulus, such that fluid in the annulus may be monitored in order to detect leakage. For example, a double-walled bellows may include an annulus between the walls, and the annulus may be in fluid communication with a port. Detection of fluid at the port may be indicative of leakage, and one or more action may be taken in response to such fluid detection. In some embodiments, the double-walled bellows may be formed by having an elastomeric liner disposed within a single-walled bellows, which may have an accordion-like configuration. Related methods and systems are also disclosed.
