The CLC/TS 50537 series “Railway applications – Mounted parts of the traction transformer and
cooling system” consists of four different parts:
• Part 1: HV bushing for traction transformers;
• Part 2: Pump for insulating liquid for traction transformers and reactors;
• Part 3: Water pump for traction converters;
• Part 4: Gas and liquid actuated (Buchholz) relay for liquid immersed transformers and reactors
with conservator for rail vehicles.

The CLC/TS 50537 series shall be read in conjunction with CLC/TS 50534 “Railway applications -
Generic system architectures for onboard electric auxiliary power systems”.
This standardization project was derived from the EU-funded Research project MODTRAIN
(MODPOWER). It is part of a series of standards, referring to each other. The hierarchy of the
standards is intended to be as follows:

1 Scope
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.
