Happy New Year from Tesla Submersible Motors!!

-> 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 6" TR6 series


Three-phase submersible motors, asynchronous, two poles, rewindable, made up of stainless steel AISI 304 and cast iron with PVC windings in the standard version. Mitchell type thrust bearing. Cooling and lubrication of the thrust bearing system is granted by a mixture of glycole and water. Connection according to NEMA 6“ standard. Degree of protection IP 58 (on request IP68). Operation: vertical/horizontal (a minimum thrust must be applied on the thrust bearing pads). Motor protection must be granted by user. On request supports made up of AISI 316 or 904, windings in PE2+PA and mechanical seal in SiC/SiC.
