Modern high-speed trains are equipped with KSB canned motor pumps from the Etaseco series to cool the trains’ power electronics (Photo: KSB).

The pumps manufactured at KSB’s Pegnitz factory are used for cooling the power converters in traction systems.

Depending on the rated motor power, the converters for traction systems are either cooled by air or liquid. Today, the large electric drives mainly require liquid-cooled power converters.

In the cooling system, a zero-leakage canned motor pump ensures that a glycol/water mixture is circulated at a discharge pressure of up to 4 bar. The coolant temperature may vary between -50°C and +80°C max., depending on the climatic conditions.

One reason why this pump type has been so successful in these applications is that it meets high requirements with regard to quality, vibration characteristics, noise levels, service intervals and MTBF value (Mean Time Beween Failures).

Before the pump is actually used in railway applications, it has to undergo comprehensive testing to prove it is compliant with EN 60349-2 and EN 61373.

KSB pumps are currently employed in locomotives in countries all over the world, such as

  • Australia (Queensland)

  • Belgium

  • Bulgaria

  • China (DJ8, DJ4, CHN)

  • Denmark

  • Germany (ICE-3, BR 426-426, BR 185.2, BR 189)

  • France (TGV–POS, NAT)

  • Great Britain

  • Italy (E464, AGV)

  • Korea

  • Lithuania

  • Austria (ÖBB 1016/1116, 2016)

  • Portugal

  • Russia

  • Switzerland (Zurich urban train)

  • Spain

  • USA (NJT).

Canned Motor Pump Technology Has Multiple Advantages

13.03.2024 -

Using canned motor technology for submersible pumps provides significant advantages. A short shaft, only two slide bearings – independent from the immersion depth – and various monitoring functions not only ensure high reliability but also mean cost advantages for the operator. Since it is supplied as a lock pump, easy servicing is guaranteed at the same time.
