Installation Manual |
OVERVIEW
BF MOTOR DESCRIPTION
PRELIMINARY INSPECTION
TOPPING THE MOTOR FLUID
This manual gives information about the correct use and installation of the 6", 8" and 10" BF
Motors Series.
Instructions and prescriptions refer to the standard installation: for any special arrangement
please contact Britefil Technical Department.
Any improper use of the motor may cause damage to the motor and to the plant; and
invalidates product warranty.
Stator impregnated with a special epoxy resin and hermetically sealed, in order
to guarantee the best electrical insulation and the most efficient cooling.
Rotor and bearings lubricated with a solution of water and polypropylenic glycol.
Removable cable connector.
AISI 304 outer sleeve.
AISI 431 splined shaft end.
Option AISI 316
Option Cast iron G20 upper bracket.
Motor sealing provided by labyrinth sand slinger mechanical seal.
Visually check the motor integrity, in order to find possible damages due to
transportation.
Check the insulation resistance with a megger before installation: referring to a
brand new motor, the resistance must be over 500 Mohm.
Check power and voltage according to the application.
Manually check that the shaft can rotate.
Before the installation, check the motor fluid level and refill if necessary.
Refill the motor with clean water as follows:
5.
4.
6.
1.
3.
2.
Stand the motor vertically and take the plug off using an
hexagon screw driver (5mm).
Turn the motor shaft by hand and rock the motor gently
to and fro.
Refix the plug portation.
Turn the motor shaft by hand and rock the motor gently
to and fro again.
Check the liquid level and if necessary refill again.
Refill with water until fluid is full to the brim.

Installation Manual |
APPLICATIONS
- domestic and agricultural irrigation;
- water supply from deep wells;
The BF Motors can be coupled with any 6", 8" and 10" submersible pump having the flange and
joint dimensions according to NEMA standards.
The motor is designed to be submerged and it is suitable for the following applications:
- booster pressurizing.
Pumping explosive liquids or using the motor in hazardous environments
is strictly forbidden!
APPLICATION LIMITS
Water pH: 5.5 - 7
Vertical or horizontal use is allowed.
If the motor is powered by an electric generating set, we recommend to:
- stop the motor before the generating set
If the motor is combined with a frequency converter, please contact Britefil Technical
Department.
Remind that in case of using the motor in aggressive environments, any anomaly or
malfunction are under the responsability of the installator.
Pt100 Temperature sensor is available under request.
- start the generating set before the motor.
Minimum cooling flow rate: 0.16 m/s
Maximum startings per hour: 20 fro D.O.L.
Voltage tolerance: ± 10%
Maximum immersion depth: 350 m
Maximum water temperature: 35ºC, with PE2/PA go to 50ºC, available under request.
APPLICATION LIMITS
Concerning the connection, please follow the instructions supplied with the cable
junction kit.
Fix the cable to the delivery pipe in order to avoid damages.
The BF Motors has been designed to work only submerged.
A cable is provided: do not damage the motor while moving it and do not lift the motor
by the cable.
After mounting the pump, check that the shaft is able to rotate and put some grease on
the joint.
Make sure that the motor does not touch the bottom of the well| Sand may
damage the diaphragm, so keep the motor at least 1 m over the bottom of
the well!

ELECTRICAL INSTALLATION
For further information, please contact Britefil Technical Department.
A high sensitivity circuit breaker device is recommended.
Electrical connection: check the colors on the motor rating plate and refer to the
schemes at the end of this manual if necessary.
Fuses and overload protections are recommended in order to keep the motor safe.
Motor has to be earthed according to local regulation!
