Z855 – Z875 Z895 – Z8125 SERIES

Submersible
motors
FW8
Series
APPLICATIONS
Three-phase asynchronous submersible water-filled
motor, with short-circuit rotor and special water resistant
windings.
The choice of component materials ensures optimum
operating performances, superior quality, reliability and
ease of installation.
SPECIFICATIONS
• Shaft extension and coupling
dimensions to NEMA standards.
Rewindable stator
PVC insulation
Protection class: IP68
Fill liquid
The motors are filled with water
containing non-toxic antifreeze. This
liquid, besides protecting the motor
from low temperatures, helps to
inhibit oxidation and improve
lubrication.
• Large compensating
diaphragm for internal liquid
expansion. The motor is also
equipped with a relief valve
enabling the escape of liquid in the
event of abnormal temperature
increases.
• Axial load supported by oscillating
bearing.
• To prevent fluid exchange between
the external and internal
environments, all the standard
motors are equipped with a silicon
carbide mechanical seal.
• Maximum immersion depth:
350 metres.
• Maximum number of evenly
distributed starts per hour: 10
• Maximum supply voltage variation
(415 V +6%, 380 V –10%).
Maximum axial thrust: 45,000 N.
• Available versions:
FW8 three-phase: 45 kW to 93 kW
380-415 V; different voltages
available on request.
PVC winding
•
cable.
•
The motors are supplied with 6 m
Ambient temperature: 30°C. The
motors must operate in installations
ensuring a minimum water velocity
around the motor sleeve of 0.20
m/s for 30-52 kW, 0.5 m/s for 55-
93 kW.
OPTIONAL
FEATURES
Special voltages.
• Horizontal installation: all models
except for the 93 kW one.
Inverter applications.
High temperature windings.
• Different materials.
ACCESSORIES
• Panels.
Drop cables.
