Abstract

An oilfield pump employing a linear electric motor. The linear electric motor replaces a conventional crankshaft or hydraulic techniques for driving a plunger of the pump. This may reduce the number of equipment parts and amount of maintenance expenses associated with the operation of oilfield pumps. Furthermore, the use of a linear electric motor may also increase the precision and control over the fluid delivery provided by the pump assembly.
