Use Of Colling Jackets
• Cooling of submersible motors is provided with the flow of the water around it. That’s why water flow around motors has vital importance during submersible pump installation. This flow rate depends on diameter and power of motor.
• Most important factor of submersible motors’ long service life is that the motor must have adequate flow for proper cooling.
• If the motor will be installed in an open body of water (i.e pool) or diameter of the well is much bigger than the diameter of the motor, Flow Inducer Sleeve must be used to provide the flow velocities that are given in the table below, around the motor.
