1. A pump, comprising:
a bore pump fluid end having a reciprocating plunger bore;
a reciprocating plunger having a front end opposite a fluid intake end and comprising a peripheral wall defining a hollow cylindrical body;
a movable manifold comprising a reciprocating plunger end and a fluid intake end;
in which the reciprocating plunger end of the movable manifold is fluidly connected with the fluid intake end of the reciprocating plunger, whereby the reciprocating plunger end of the movable manifold moves in the same axial direction as the reciprocating plunger during reciprocation of the reciprocating plunger along a path within the reciprocating plunger bore of the bore pump fluid end; and
in which the fluid intake end of the movable manifold is configured for fluid coupling with a stationary fluid manifold such that the fluid can be introduced into the movable manifold via the stationary fluid manifold and the fluid intake end of the movable manifold; and
a power end attached to the bore pump fluid end and comprising a rotatable crankshaft, the rotatable crankshaft operatively connected to the reciprocating plunger and operable to reciprocate the reciprocating plunger in the reciprocating plunger bore of the bore pump fluid end.
