Abstract:
A method for manipulating a pump, the pump including a rotor received inside a stator tube, the rotor being rotatable relative to said stator tube to pump material through said stator tube, the method comprising the steps of:providing an apparatus including an actuator assembly having a base and a piston that is displaceable relative to said base along a first axis and a pusher rod located adjacent to said piston; attaching said base to a discharge end of said stator tube; coupling said pusher rod to said piston for movement along said first axis; and activating said actuator assembly such that said piston and pusher rod are displaced relative to said base along said first axis such that a working-end of said pusher rod engages said rotor which provides a resistive force as said base and stator tube are spaced away from said rotor along said first axis by said actuator assembly.
