Abstract

A reciprocating piston of a positive displacement pump has a piston body with a plurality of cooling fins on one or more exterior surfaces of the piston body. A seal coupled to the piston body forms a seal with the walls of a cylinder in the positive displacement pump. A rod moves the piston within the cylinder to cause the displacement of fluid.
