Claim 6:
7. 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 first end having a fluid inlet opposite a second end having a fluid outlet, wherein the second end of the reciprocating element adapter is connected to and in fluid communication with the fluid intake end of the reciprocating element;
a pump power end having a push rod connected to the first end of the reciprocating element adapter, the pump power end operable to reciprocate the reciprocating element in the reciprocating element bore of the pump fluid end, wherein the pump fluid end and the pump power end are separated by a minimum spacing distance;
a packing assembly comprising a packing screw, a packing carrier, and a packing, wherein the packing screw, the packing carrier, and the packing are each cylindrical and have a width measured along a central axis thereof that is less than the minimum spacing distance, wherein the central axis thereof is coaxial with a central axis of the pump fluid end, wherein a front side of the packing carrier distal the pump power end is in contact with a back side of the packing proximate the pump power end, wherein at least a portion of a front side of the packing screw distal the pump power end is in contact with a back side of the packing carrier proximate the pump power end, and the packing screw is coupled with an inside surface of the reciprocating element bore of the pump fluid end, whereby the packing screw retains the packing carrier and the packing within the reciprocating element bore during operation of the pump; 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,
wherein the minimum spacing distance is an axial distance measured along the central axis between a back of the pump fluid end and a front end of the reciprocating element adapter when a crankshaft is at top dead center (TDC), and wherein the back of the pump fluid end is axially proximal the pump power end.
