Deep Well Submersible Pump Motors (Without Pump)
Deep Well Submersible Motor
A deep well submersible motor is an electric motor mounted below the pump stage in a borehole and operates submerged in water. It is filled with water (or specialist fluid) and cooled by the flow of borehole water; together with the pump stage, it forms a complete submersible pump assembly.
Available in 4″, 5″, 6″, 8″ and larger diameters, from 0.5 HP to 250 HP, in single-phase and three-phase. Rewound-type models are available, and larger power units are suitable for star-delta starting; 4″ and 6″ motors use standard NEMA connection dimensions.
