Hvdp Series Stator Removal, Inspection, And Installation; Hvdp Series Drive Removal, Inspection, And Installation - Finish Thompson HVDP Series Operation-Installation-Parts Manual

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.
SECTION 3: STATOR REMOVAL, INSPECTION & INSTALLATION
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 4: DRIVE ASSEMBLY REMOVAL & INSTALLATION
REMOVAL:
1. Remove the motor (see section 1 and follow the instructions for your model).
2. Remove stator (see section 2).
3. Remove the bail wire (see Figure 3).
4. Release the cam-lock by pulling the cam-lock levers towards the top of the drive assembly.
5. Pull the drive assembly out of the pump tube assembly while holding the cam-lock levers in the upright position.
INSTALLATION:
1. Make sure that the locating stud on the back of the pump tube assembly is aligned with the drive assembly coupling.
2. Push the drive assembly into the pump tube assembly while holding the cam lock levers in the upright position.
3. Rotate the cam-lock levers downward.
4. Install the bail wire.
5. Install stator.
