Abstract
A pump assembly including a power end including an output shaft having an output shaft axis. In addition, the pump assembly includes a fluid end including a piston configured to reciprocate to pressurize the working fluid. Further, the pump assembly includes a transmission coupled to each of the power end and the fluid end. The transmission includes a carriage coupled to the piston and a pivoting arm pivotably coupled to the carriage at a first connection about a first pivot axis. The first pivot axis extends in a perpendicular direction to a direction of the output shaft axis, and rotation of the output shaft about the output shaft axis is configured to cause the pivoting arm to pivot about the first pivot axis at the first connection and to cause the carriage to reciprocate.
