Abstract: A reciprocating pump assembly includes a fluid end section having a pressure chamber and a plunger bore that fluidly communicates with the pressure chamber. The reciprocating pump assembly includes a plunger configured to be held within the plunger bore of the fluid end section, and a linear actuator operatively connected to the plunger such that the linear actuator is configured to reciprocate the plunger within the plunger bore during operation of the reciprocating pump to thereby pump fluid through the fluid end section.
