摘要： A disclosed submersible pump apparatus includes a three-dimensional frame, a pump housing, a drive shaft, an impeller, and first and second motors. The impeller is mounted on the driveshaft within the pump housing and is driven by one or both of the motors. The first motor is connected to a first end of the drive shaft and the second motor connected a second end of the drive shaft. The first and second motors are hydraulic motors and in a first configuration, the first and second motors are configured to cooperatively rotate the drive shaft with hydraulic fluid supplied to and removed from the first and second motors using a parallel fluidic connection. In a second configuration, only one of the motors has a drive gear and drives the drive shaft while the second motor does not have a drive gear and acts as a frictionless bearing supporting the drive shaft.
