AID - Franklin Electric Europa

Franklin Application/Installation Data Europe No. 1/2009For years now, coastal regions are experiencing a decrease in well water quality. From asubmersible motor manufacturer’s perspective, this creates corrosion failures on motorsbuilt with standard AISI 304 stainless steel components. While motors of higher grade (AISI316) materials are available, cost implications often prevent these solutions from beingadopted.In this issue of our FE Aid Bulletin we want to demonstrate how you can extend the servicelife of standard 304 SS motors by means of a couple of simple tricks, even when employedin adverse water conditions.1. Sacrificial anodes for 4“ SS and HT motors, which can easily be assembled to thebottom part of the submersible motor:4“ SS FE no. 308250912; 4“ HT FE no. 3082509132. Stainless steel fitting with galvanized pipe at the pump outlet:Length approx. 0,5- 0,75 m3. Potential adjustment between upper end bell of motor and galvanized pipe.4. A proper, low resistance connection of potential equalizing wires to motor and pipe.Information on our free-of-charge seminars at theTraining Center in Wittlich/Germany can be obtained by visiting following link:http://www.franklin-electric.de/de/training.aspYourFranklin Electric Field Service Team
