APPLICATIONS
Used in a variety of residential, commercial and
industrial applications such as:
• Sewage systems, Flood and Pollution Control,
Dewatering/Effluent, Farms, Hospitals, Trailer Courts,
Motels

• 1.5 - 5 HP, 208 and 230 volts
e Built-in thermal overloads with automatic reset
e Built-in capacitors
MODELAND MOTOR
Throe Phase:
• 1.5 - 7.5 HP; 200, 230,460 and 575 volts
• Class 10 overload protection must be provided in
control panel
MOTORS
• Fully submerged in oil -filled chamber: High grade
turbine oil surrounds motor for more efficient heat
dissipation, permanent lubrication of bearings and
mechanical seal for complete protection against
outside environment.
• Class F insulation
• Designed for Continuous Operation: Pump ratings
are within the motor manufacturer's recommended
working limits and can be operated continuously
without damage when fully submerged.
• Bearings: Upper and lower heavy duty ball bearing
construction for precision positioning of parts and
to carry thrust loads.
• Power Cable: Severe duty rated, oil and water
resistant. Epoxy seal on motor end provides
secondary moisture barrier in case of outer
jacket damage and to prevent oil wicking. 20 foot
standard with optional lengths available.
• O-ring: Assures positive sealing against
contaminants and oil leakage.
