EN 50216-7 covers requirements for electric pumps which generate the circulation of insulating oil in transformers and reactors conforming to the EN 60076 series and their associated cooling systems.The pumps covered in this standard are rotodynamic pumps driven by a squirrel cage induction motor which is immersed in the insulating oil.Pump sets conforming to this standard may be of in-line or end suction design.This standard includes requirements for the electrical and hydraulic performance, mechanical design, routine testing and type testing. Additionally, performance and dimensions of preferred sizes of pump sets are specified (see normative annexes A and B).The insulating oils considered comply with subclause 2.5 of IEC 60296-1. If other insulating liquids are to be used, the performance and design of the pump shall be agreed between purchaser and manufacturer.
