A method for operating a progressive cavity pump wherein the stator has at least first and second active stator sections that are at different locations on the stator, comprising inserting a first rotor having a first active rotor section that is aligned with the first active stator section, and rotating the first rotor relative to the first active stator section such that the aligned first active rotor and stator sections generate a pumping force. Subsequently, the first rotor is removed and a second rotor is inserted having a second active rotor section that is aligned with the second active stator section, and rotating the second rotor relative to the second active stator section such that the aligned second active rotor and stator sections generate a pumping force.
