Encapsulated submersible motor has the following characteristics:

Good sealing ‌ : the motor stator is strictly closed by non-magnetic stainless steel thin-wall shielding sleeve, end ring and shell of the sealing chamber, filled with solid filler, can effectively prevent the intrusion of moisture and impurities ‌

Wide application scenarios ‌ : suitable for all kinds of underwater environment, such as underground, rivers, lakes, oceans and other occasions ‌

High sand resistance ‌ : designed with sand ring and double mechanical seal to ensure high sand resistance ‌
