All about Schaeffler’s electric auxiliary water pumps

Schaeffler has introduced a range of electric auxiliary water pumps under the INA brand. The range meets OEM standards and offers wide coverage of the European vehicle parc.

Efficient and reliable engine cooling solutions are essential to ensure optimum operating temperatures and thermal load on critical components, according to Schaeffler, with thermal management becoming more challenging as EVs can place higher demands on the cooling system, whilst also increasing system complexity.

Auxiliary water pumps can play a major role in after-run, fuel and turbocharger cooling. They are also essential for cooling the high-voltage battery and the inverter in hybrid and EVs.

Initially, Schaeffler is launching 11 INA auxiliary water pumps for high-volume vehicles from manufacturers, including Toyota and Volkswagen. The range will be expanded during this year and beyond.

One highlight is a pump for Toyota, Volvo and Lexus models used for hybrid inverter cooling (part number 539 0006 10). Pumps launched for VAG manage additional cooling of the water circuit and after-run cooling when the engine is switched off (part numbers 539 0010 10 and 539 0014 10).
