This Technical 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 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 enabling the
interchangeability especially regarding electrical, mechanical and hydraulic interfaces. Furthermore,
service conditions are described.
