27、cal Specification covers requirements for centrifugal and peripheral electric pumps which generate the circulation of cooling liquid in converters of rail vehicles and their associated cooling system. The pumps covered in this Technical Specification are rotodynamic pumps driven by canned motors or
28、magnetically coupled motors. CLC/TS 50537-3 gives consideration to both technical and normative requirements of the railway environment and restricts the variety provided by industry-wide standards for pumps (for example EN 50216-7, EN 733 and EN ISO 9906). It determines requirements and tests enabl
