1. A lightweight reciprocating plunger for a high pressure pump comprising:
a plunger body defining a cavity, the plunger body having a closed distal end and an open proximal end opposite the closed distal end, wherein the plunger body is configured to reciprocate within and with respect to one or more packing seals to apply a pressure to a working fluid in a fluid end of the high pressure pump, wherein the cavity extends from the open proximal end towards the closed distal end; and
an insert disposed in the cavity, wherein the insert comprises an agitator configured to move freely within the cavity to prevent debris from accumulating within the cavity.
