A pumping system for use in moving a fluid present within a well casing and through a production tubing is provided. The pumping system includes a housing coupled to the production tubing. The pumping system further includes a first pump coupled to the housing and having a first flow capacity and a second pump coupled to the housing and having a second flow capacity. The second flow capacity is different than the first flow capacity. A motor is coupled to the first pump and the second pump, wherein the motor is configured to selectively operate at least one of the first pump and the second pump based on a flow capacity of the fluid present within the well casing.
