    Abstract: Disclosed embodiments may relate to pumps for introducing treatment fluid into a well. For example, a piston-driven bellows pump may include a power end, having a piston disposed in a power end bore; a fluid end, having a fluid end bore and a chamber in fluid communication with a suction valve and a discharge valve; and an expandable bellows disposed in the chamber and in fluid communication with the fluid end bore. In embodiments, the power end can be configured to reciprocally expand and contract the bellows within the chamber based on movement of fluid by the piston. 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.

    Abstract: An assembly comprises a tubular housing having a bore therethrough and at least one stimulation port therein to communicate fluid from the bore to outside the tubular housing and a sleeve axially movable in the tubular housing. The sleeve comprises a first baffle and a second baffle. The sleeve is initially in a first closed position, wherein the sleeve is to axially move from the first closed position to an open position in response to the first baffle receiving a first object therein, wherein the at least one stimulation port is open in the open position. The sleeve is to axially move from the open position to a second closed position in response to the second baffle receiving a second object received therein, wherein the second object is larger than the first object, where the at least one stimulation port is closed in the second closed position.
