THOROUGHLY REVIEW ALL INSTRUCTIONS AND WARNINGS PRIOR TO PERFORMING
ANY WORK ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.
Indicates a potentially hazardous situation which, if not avoided, will result in death
or serious injury. Hazards identied by the signal word WARNING present a lesser
degree of risk of injury or death than those identied by the signal word DANGER.
Indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury. CAUTION may also be used to alert against unsafe practices associated
with events that could lead to personal injury.
Used without the Safety Alert Symbol indicates a potentially hazardous situation which,
if not avoided, may result in property damage.

II. Overview
This manual gives important information concerning the installation, use and maintenance of the motors.
The contents of this manual refer to the standard product, as presented in the sales documentation. Any
special versions will be supplied with supplementary instruction sheets. Please refer to the sales contract for
the features of variants and special versions. Always specify the exact type of motor and code when requesting our Sales and Service Department for technical information or spare parts. For any instructions, situations
and events not covered in this manual or in the sales documentation, please contact the nearest Technical
Assistance Center.
Read this manual carefully before installing and using the product.
Improper use may cause personal injury and/or damage to property, and invalidate the warranty.
III. Product Description
The CentriPro CP-Series comprises 6”, 8”, 10” and 12” submersible rewindable motors with stator and rotor
immersed in a bath of lubricating liquid consisting of demineralised water and anti-freeze. 6" and 8" motors
are equipped with NEMA-standard ange and shaft dimensions. For 10" and 12" motor sizes please consult
this product's technical bulletin for mounting dimensional details.
Overview and Product Description
All the metal parts in contact with the water are either made from stainless steel or cast iron.
Each motor includes a Kingsbury pivoted-shoe thrust bearing and winding wire. The winding wire will be
either standard or special high temperature type.

Handling and Installation
IV. Handling and Installation
1. Do not use lead wires to pull, lift or handle the motor. The lead wires should be protected during storage,
handling, moving and installation of the motor.
2. Inspect the motor to determine that it is the correct HP, voltage and size for the job and that there is no
shipping damage.
3. The factory-installed water in the motor is supplied with antifreeze capable of temperatures to -5º C (23º F).
Do not install, transport or store below these temperatures. If storage is necessary below these temperatures,
drain the water from the motor.
4. After long periods of idleness and on all new installations, check the electrical resistance and megger the
motor with lead wires connected. The insulation resistance should have a value of at least 5 megohms at
installation and at least 1 megohm after running.
5. Verify motor is lled with clean water before installing. The warranty is void if this is not done. Also check
the tightness of all water lling and drain plugs, mounting bolts and cable connections.
6. Do not hammer the shaft, coupling or slinger since this may damage the thrust bearing. Check the rotation
of the motor by hand to insure that it turns freely.
7. Do not drop the bottom end of the motor in the dirt or mud since this may plug up the diaphragm opening.
8. If motor is to be installed horizontally, make sure the relief valve is at the 12 o'clock position when facing the
motor shaft (in horizontal position).
9. Check that winding coil resistance in each two phases is equal to values in Tables 1 - 4.
10. Select the proper overload relay or heaters.
11. For 50HP and 60HP models: Remove the metal sleeve attached to the midpoint of the motor and discard.

COMPONENTS REQUIRED FOR CORRECT INSTALLATION
• Control panel equipped with a main switch and thermal relay for
overload protection.
• Check valve at 30 feet distance from the delivery ports, plus an
additional non-return valve every 100-165 feet of piping.
• Gauge and gate valve at well mouth.
• Electronic probes or oats for protection against dry running.
RECOMMENDATIONS
• Secure the drop cable to the pipe every 6-10 feet of piping.
• Make sure the motor is installed at a safe distance from the bottom of
the well.
• Make sure there is a minimum distance of .13 inches between the
diameter of the pump and the internal diameter of the well.
• During operation, make sure that the water circulation speed around the
motor is per Section VI #1.
• Make sure that the minimum dynamic level of the water in the well is at
least 3 feet above the pump’s delivery port.

WARNING
IV. Handling and Installation (continued)
Before installing the motor, read this instruction manual and the one supplied with the pump
or electric pump to which the motor will be coupled. Keep both manuals in a safe place for
future reference.
Selecting the electrical panel
Make sure the panel power ratings match those of the pump. Incompatible combinations
may cause faults and fail to fully protect the motor.
Before installing, carefully read the instructions supplied with the electrical panel.
Checking the motor liquid level
Place the motor in the vertical position, with the air valve facing upwards. Unscrew the air
valve from its hole. Add clean water using a syringe, until the water overows the hole. Make
sure the valve is not clogged. If necessary, clean it or replace it. Screw the valve back into the hole.
Installation in a well or tank
When installing the electric pump vertically, make sure the motor does not rest on the bottom of the
well or tank.
When installing the electric pump horizontally, make sure the motor does not rest on the bottom of the tank.
Electrical connections to the electric motor
Make sure that the supply voltage and frequency are compatible with the electrical panel. The
relative information is shown on the motor rating plate and in the documents supplied with
the panel. Provide suitable short circuit protection on the supply line.
Before proceeding, make sure that all the connections (even if they are potential-free) are

voltage-free. Unless otherwise specied in local bylaws, the supply line must be tted with:
• a short circuit protection device
• a high sensitivity residual current circuit breaker (30mA) for additional protection from
electrocution in case of inefcient grounding.
• a disconnect switch with a contact aperture of at least 3 mm.
Ground the system in compliance with current regulations. Attach the included lead wire to the upper endbell.
