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.

-> teslasub.it gets a new look
New TESLA website is now online. Reflecting the new and more modern look of Tesla, the website has been fully re-designed, to allow an immediate access to products technical sheet. The download section, at the moment under construction, will be soon ready, with all the newest technical and commercial documents.

CSA/UL APPROVAL
it is with great pleasure that we wish to inform you that our complete assortment of 4 canned type submersible motors do meet the cCSAus as per the safety standard of CSA C22.2 No. 100-04 and UL 1004. Do not hesitate to contact our offices for more details. The official document will be available shortly in our web site.

 
Submersible motor 4 GG series


4 series high performance water filled submersible motors made of AISI 304 stainless steel (parts in contact with water). 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.

COMPONENTS
 All Tesla motors are provided with removable cable connector. This solution allows fast assembly/disassembly of the hydraulic part and facilitates maintenance operations.   
 Kingsbury type thrust bearing unit consisting of tilting pads made of highly-resistant stainless steel and machined by Tesla using the spherical lapping process; this machining guarantees to this strategic component high reliability and high resistance to axial load.   
 Shaft made of AISI 304 with a special process of surface hardening and polishing of the working area of the bushes; rotor with copper cage for motors with power exceeding 4 HP.  
 Encapsulated stator with outer casing made of AISI 304L. The stator has 24 slots for better elasticity and regularity of operation; class H double insulated copper wire.
