A pump apparatus includes a gear pump assembly interposed between top and bottom drive gear assemblies, and coupler assemblies interposed between a bottom of the top drive gear assembly and a top of the gear pump assembly, and between a top of the bottom drive gear assembly and a bottom of the gear pump assembly. The drive assemblies rotate a pre-feed auger. A cyclone screen located within a cyclone housing is positioned over a shaft of the pre-feed auger and interposed between a blade of the pre- feed auger and the bottom drive gear assembly. An intake housing is positioned over the blade of the pre-feed auger, and regulates fluid intake into the pump. As fluid is taken into the pump, it is caused to spin by the action of the auger. This causes solids to be separated from the fluid and to be expelled through exhaust ports in the pump apparatus. As a result, fewer solids are permitted to travel northward with the pumped fluid, thereby helping to protect the components of the pump. The entire pump may be coupled, at a north end thereof, to a hydraulic pump, hydraulic motor, electric motor, or drive rod/shaft powered at the surface
