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.

Abstract: Disclosed embodiments may relate to bellows pumps for introducing treatment fluid into a well. Wear issues, for example causing leakage of the discharge valve, can lead to pressure build-up in the pump chamber which may eventually damage the bellows. Disclosed embodiments may be configured to prevent such damage to the bellows due to discharge valve leakage. For example, in some embodiments a mechanism may hold open the suction valve during pump stoppage, to prevent pressure accumulation. Alternate embodiments may be configured to protect the bellows, even when the pump continues to run. Related methods are also disclosed.

In embodiments, the power end bore and the fluid end bore may be fluidly coupled to form a unitary, continuous, and/or unbroken pump bore without external piping therebetween and/or without unswept volume therebetween. Related methods are also disclosed.
