A pump includes a stationary pump housing having a housing chamber, a rotating pump shaft having a central longitudinal axis and extending through a proximal end of the pump housing into the housing chamber, and a rotating swash plate fixed to the pump shaft. The swash plate includes a pump inlet passage with an opening in a surface of the rotating swash plate. A plurality of reciprocating pump pistons are also included with the pump, each pump piston is at least partially contained within a respective pump chamber formed in the stationary pump housing and has an axial bore extending completely therethrough. The axial bore of each pump piston may selectively communicate with the swash plate surface opening to permit the supply of inlet fluid to the axial bore from the inlet passage. A sealing plate substantially seals the swash plate surface opening from a flow of fluid into the inlet passage from the swash plate surface opening.
