Overview
This Technical Specification specifies requirements for centrifugal and peripheral electric pumps which generate the circulation of cooling liquid in converters of rail vehicles and their associated cooling systems. The pumps covered in this Technical Specification are rotodynamic pumps driven by canned motors or 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 standards, such as EN 50216-7, EN 733 and EN ISO 9906. It specifies requirements and tests enabling the interchangeability, especially regarding electrical, mechanical and hydraulic interfaces. Furthermore, operating conditions are described. The responsible Committee is Subcommittee UK 351.1 "Fahrzeuge" ("Rolling stock") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
