7" Submersible Motors
7" Submersible Motors
Produced for wells 180 mm. internal diameter, Impo Submersible Motor Series reduces the total purchasing cost with its high efficiency. Water lubricated radial and Kingsburry type axial bearings are maintenance-free. Hot water resistant. Pressure balancing between inner and outer side with a rubber membrane at the bottom side and with a pressure plug at the top side of the motor. All Impo product is delivered after they pass the 100% quality control and tests.
Advantages
With a diameter of 165 mm, it is produced for wells of larger than 180 mm inner diameter.
When coupled to 7 inch pumps in 8 inch inclined wells, well rehabilitation may not be required.
When used in 8 inch wells, enables larger flow rates for large pumps when compared to 8 inch motors.
Contains a special wire that is suitable for hot water applications in its standard design.
Rewindable stator reduces repair and maintenance costs.
Provides an advantage as it can be used together with 6 inch pumps in applications where mechanical strength is important.
