Description
Submersible motors are electric motors with IP68 protection for pumps operating underwater, primarily in irrigation systems and at water intakes. The website states a range of 200–250 kW for irrigation, and the catalogue 'Synchronous & Induction Machines' mentions high-voltage submersible motors up to 2 MW. A submersible motor works in a very confined space and has a large length-to-diameter ratio; the design keeps compact dimensions while meeting requirements for efficiency, thermal behaviour, cooling and protection degree. Cooling is closed-circuit, with no contact between the internal and external environment: depending on the pump layout, heat is removed by the pumped liquid flowing over the housing or by a water jacket. Bearings are maintenance-free, with oil cooling or grease lubrication for the full service life. The housing is made of special cast steel or stainless steel and is designed for permanent immersion without corrosion of the stator; the shaft is of precision-machined stainless steel with seats for mechanical seals. Special mechanical seals and watertight cable glands withstand water or liquid pressure up to 4 bar. Motors are designed to the pump's torque requirements and can be started direct-on-line or from a variable frequency drive. Production takes place at the plant in Bangalore (India).
