SAFETY PRECAUTIONS
read the installation instructions before operating the pump.
ALWAYS
wear protective clothing, eye protection and follow standard safety procedures when handling corrosive or
ALWAYS
personally harmful materials.
use protective gloves to prevent contact with hot surfaces.
ALWAYS
use an open, splash proof or TEFC motors when pumping or mixing ammable or combustible material.
NEVER
place the pump intake in uid before starting the pump.
ALWAYS
make sure the discharge hose and pump are both secured and properly supported before starting the pump.
ALWAYS
make sure the pump is properly grounded when pumping ammable or combustible materials. This requires
ALWAYS
a static protection kit.
use a discharge hose that is chemically compatible with the uid being pumped and is rated at the discharge
ALWAYS
temperature and pressure of the pump installation.
NEVER use the pump in pressurized containers.
MAINTENANCE PRECAUTIONS
check motor rotation on LR versions (air and induction motors) before installing the motor onto the pump.
ALWAYS
store the pump and motor upright and away from corrosive liquids and vapors.
ALWAYS
check compatibility and temperature range of the pump with the liquids being used.
ALWAYS
ush the unit after each use if the liquid being pumped can crystallize or harden.
ALWAYS
re-lubricate the pump internals after cleaning.
ALWAYS
pump liquids containing solids that can damage internal pump parts (i.e. metal chips).
NEVER
allow the pump to run dry.
NEVER
operate the pump against a closed discharge. If the pump is operated against a closed discharge, a bypass (pres-
NEVER
sure relief valve) must be used.
NOTE: Pumping solid can lead to increased wear on the stator and rotor.

HVDP SERIES ASSEMBLY, MAINTENANCE & CLEANING INSTRUCTIONS
SECTION 1: MOTOR INSTALLATION AND REMOVAL
INSTALLATION - HVDP-HR
1. Locate the rubber coupling insert that was separately shipped in a plastic bag (see Figure 1).
2. Install the rubber coupling insert onto the metal coupling half located on top of the HR drive
assembly.
3. Find the metal coupling half located inside the HR motor. Align this coupling with rubber insert
installed in the second step of these instructions.
4. Slide the HR motor onto the HR drive assembly.
5. Hand tighten the motor nut onto the threaded nose of the HR motor.
HVDP-HR REMOVAL: To remove the HR motor, reverse HR motor installation instructions
found in this section.
Figure 1
INSTALLATION - HVDP-LR
1. Check the rotation direction of the LR motor.
WARNING: Motor rotation must be clockwise when viewed from the fan end of the motor. Rotating the motor in the wrong direction
will cause damage to the pump.
2. Remove the motor adapter bolts (see Figure 2) and separate the motor adapter from the motor.
3. Thread the motor adapter onto the LR drive assembly. Hand tighten the motor adapter.
Note: Threads are left-handed. Also, thread lubricant is recommended to ensure smooth, bind free assembly.
4. The LR motor coupling consists of two 5/16” diameter pins welded to a hub. The LR drive assembly coupling has two slots that
receive these pins. Align the pins of the motor coupling with the slots on the drive assembly coupling and slide the motor onto
the drive assembly.
Note: Make sure the coupling is engaged properly and the motor adapter face is flush with the motor face.
5. Rotate the motor until the motor adapter mounting holes align with the threaded holes in the motor face.
6. Install the motor adapter bolts and torque to approximately 7 ft.-lbs. (9.5 N•M)
HVDP-LR REMOVAL:
1. Remove the LR motor adapter bolts.
2. Remove the LR motor.

SECTION 2: STATOR REMOVAL, INSPECTION, AND 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: Inspect the stator for gouging and excessive wear. Contact FTI if you are
questioning the condition of the stator.
INSTALLATION: Reverse the removal instructions found in this section.

SECTION 3: DRIVE ASSEMBLY REMOVAL AND INSTALLATION
Figure 5
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.

SECTION 4: ROTOR REMOVAL, INSPECTION, AND INSTALLATION
REMOVAL:
1. Remove the motor (see section 1 and follow the instructions for your model).
2. Remove the drive assembly (see section 3).
3. The rotor is located at the bottom of the drive assembly (see Figure 4).
4. Using 3/4” and 5/8” open-end wrenches, loosen and remove the rotor.
INSPECTION: Inspect the rotor for excessive wear and deep grooving. Contact FTI if
you are questioning the condition of the rotor.
INSTALLATION: Reverse the removal instructions found in this section.
SECTION 5: SEAL REMOVAL, INSPECTION, AND INSTALLATION
REMOVAL:
1. Remove the motor (see section 1 and follow the instructions for your model).
2. Remove stator (see section 2).
Figure 4
3. Remove the drive assembly (see section 3).
4. The seal is located at the interface between the gearbox and the drive shaft (see Figure
6).
5. Secure the pump drive coupling using a pair of pliers.
6. Using a 3/4” open-end wrench, separate the drive shaft from the gearbox.
7. Being sure to protect the polished seal-seating area of the shaft, gently remove the
rotating seal boot, spring, and spring retainer.
8. Using a thin bladed screwdriver, remove the stationary component of the seal from
the gearbox assembly.
INSPECTION: Inspect the seal for wear and scratching.
INSTALLATION:
1. Lubricate the outside diameter of the stationary seal with a compatible lubricant and carefully install it into the gearbox housing.
2. Install the spring and spring retainer onto the pump shaft.
3. Lubricate the inside of the rotating seal boot with a chemically compatible lubricant and install it onto the pump shaft.
4. Reverse steps five through one of the seal removal instructions found in this section.
