in the sales documentation, please contact the nearest Technical Assistance Centre.
Read this manual carefully before installing and using
the product.
2. PRODUCT DESCRIPTION
The 4GG-4TW-4GX-4TWX range comprises a number of 4" submersible motors with cased stator and rotor immersed in a bath of
demineralised water and anti-freeze lubricating liquid, designed to be coupled to 4" and 6" submersible pumps with NEMA-compliant flange and
coupling sizes. All the metal parts in contact with the water are either made from stainless steel or cast iron. Each motor includes a cable with
removable connector and a Kingsbury pivoted-shoe thrust bearing.
3. APPLICATIONS
All the motors in the 4GG-4TW-4GX-4TWX range can be used to drive submersible pumps in the conditions established in EN 60034-1 (IEC
60034-1) and at the supply voltage / frequency specified on the rating plate.
The shaft extension and flange size of these motors comply with NEMA MG1:2006 Rev. 1-2007.
The power of the pumps coupled to these motors must be less than or equal to that of the motors.
3.1 Working Limits
3.1.1 Liquids in which the motor can operate
This motor can be used in cold water.
Do not use this motor with corrosive or explosive liquids, or particularly dirty or hard water (impurities may deposit on the outer casing).
3.1.2 Water temperature
Minimum water temperature is + 0°C. Maximum water temperature is + 35°C as long as the flowrate of the water around the motor
does not fall below 0.2 m/s. For temperatures above + 35°C, motor output must be reduced to ensure correct cooling.
For further information, please contact our Sales and Service Department.
3.1.3 Cooling the motor
To ensure the motor is correctly cooled, make sure the flowrate of the water around the outer casing is at least 0.2 m/s when positioning
the motor in wells or tanks. At water speeds lower than 0.2 m/s, mount a cooling jacket..
For further information, please contact our Sales and Service Department.
3.1.4 Installation Position
All the motors in the range can be installed vertically. All the motors in the range can be installed horizontally as long as the axial thrust of the
pump never falls below 100 N while it is working. For special requirements, please contact our Sales and Service Department.
3.1.5 Depth of immersion
The maximum depth of immersion for all motors is 300 m.
3.1.6 Power supply requirements
Make sure the supply voltage and frequency match those indicated on the rating plate of the motor.
For further information, please contact our Sales and Service Department
