Systems and methods for artificially lifting a product from a well

Abstract

Systems and methods for providing a pump driving unit for driving an above ground pump. The pump driving unit utilizes a single prime mover and a drive train for actuating multiple components required to drive the above ground pump. Some implementations of the pump driving unit include phase separation devices, filtering units, and cooling units that may also be actuated by the drive train of the unit. Some implementations of the pump driving unit further include an enclosure and a platform for containing the unit and simplifying on-site installation.
