SECTION 4: DRIVE ASSEMBLY REMOVAL & INSTALLATION
Figure 3
REMOVAL:
1. The stator is located at the bottom of the pump tube assembly (see Figure 5).
2. Remove the stator by unthreading it from the pump tube. If the stator cannot be unthreaded by
hand, insert a screwdriver into the slots found at the bottom of the stator. Use the screwdriver to
rotate the stator.
Note: The stator has left hand threads.
INSPECTION:
1. Inspect the stator for gouging and excessive wear. Contact FTI if you are questioning the condition of
the stator.
INSTALLATION:
1. Reverse the removal instructions found in this section.

SECTION 3: STATOR REMOVAL, INSPECTION & INSTALLATION
NEVER
operate the pump against a closed discharge. If the pump is operated against a closed discharge, a bypass
(pressure relief valve) must be used.
NEVER pump liquids containing solids that can damage internal pump parts (i.e. metal chips). Pumping solids can lead to
increased wear on the stator and rotor.
