Abstract
An embodiment of a pumping unit includes a gas turbine engine, an enclosure housing the engine, an exhaust assembly connected to the engine, an air intake duct connected to the engine, and an air treatment system connected to the air intake duct. The air treatment system including one or more inlet pre-cleaners configured to eject debris. Each of the inlet pre-cleaners having a cylindrical tubular portion configured to channel air toward the air intake duct. In addition, the pumping unit includes a gearbox operatively coupled to the engine and a drive shaft having a first end operatively coupled to the gearbox. Further, the pumping unit includes a pump comprising an input shaft operatively coupled to a second end of the drive shaft, wherein the engine, the gearbox, the drive shaft, and the pump are disposed along a longitudinal axis of the pumping unit.
