Claim 0:
1. A pump comprising:
a bore pump fluid end having a reciprocating element bore;
a hollow, cylindrical reciprocating element having a front end opposite a fluid intake end;
a hollow reciprocating element adapter comprising a reciprocating element clamp end having a fluid inlet opposite a reciprocating element end having a fluid outlet, wherein the reciprocating element end of the reciprocating element adapter is connected to and in fluid communication with the fluid intake end of the reciprocating element;
a power end having a push rod connected to the reciprocating element adapter via a reciprocating element clamp, the power end operable to reciprocate the reciprocating element in the reciprocating element bore of the bore pump fluid end,
wherein the reciprocating element clamp couples the reciprocating element clamp end of the reciprocating element adapter with a reciprocating element clamp end of the pushrod of the power end, whereby a central axis of the reciprocating element is parallel to or coincident with a central axis of the pushrod, and
wherein the reciprocating element clamp has a first contact surface perpendicular to a central axis of the reciprocating element clamp in contact with the reciprocating element clamp end of the reciprocating element adaptor and a second contact surface tapered relative to the central axis of the reciprocating element clamp in contact with the reciprocating element clamp end of the pushrod; and

a movable manifold comprising a reciprocating element end and a fluid intake end, wherein the reciprocating element end of the movable manifold is connected to and in fluid communication with the fluid inlet of the reciprocating element adapter, whereby the reciprocating element end of the movable manifold moves in a same axial direction as the reciprocating element during reciprocation of the reciprocating element in alternating directions along a path within the reciprocating element bore of the bore pump fluid end, and wherein the fluid intake end of the movable manifold is configured for connection to and fluid communication with a stationary fluid manifold such that fluid can be introduced into the movable manifold via the stationary fluid manifold and the fluid intake end of the movable manifold.
