Communication of merger through incorporation according to the articles 2501 and subsequents of the C.C.
From the 1st of October 2013, TESLA srl will be merged through incorporation into the Company DAB PUMPS SPA. We would like to underline that this is merely a legal operation and does not preclude in any way the relation of partnership that has been established between us over the years. Moreover we do believe that this transaction not only strengthens our business relationship but also will bring us an added value. The TESLA brand, with its historical know-how on design and development of submersible motors for pump applications, will keep on being present into DWT Group.

Submersible motor 4 TW series


4 series high performance water filled submersible motors complete with starting capacitor. Encapsulated stator filled with inert gas avoiding the inflation of the inner casing and damages to rotor and shaft. This technology ensures that the motor can always be repaired. Lubrication of the motor and thrust bearing system is guaranteed by a water+glycol mixture; the motors are supported by Kingsbury type thrust bearing pads which ensure high axial thrust; all the motors are provided with a removable cable connector.
