Leading engine products and drive systems supplier, Dayco, is further expanding its thermal management portfolio with the introduction of electric water pumps, for not only hybrid and electric vehicles, but also for selected traditional internal combustion engine powered applications. 

When it comes EVs and selected hybrid applications, e-pumps are the only solution assuring correct temperature management of the inverters and battery packs. Vehicle manufacturers globally are under huge pressure to reduce emissions and improve fuel consumption, which is why they work in partnership with system specialists such as Dayco to develop original equipment solutions, to achieve these objectives.

Additionally, to maximize efficiencies for ICE thermal management, maintaining different operating temperatures around the engine is a necessity. To optimize the combustion process for example, the cylinder head area needs to run several degrees hotter than the block, where, to enhance the performance characteristics of the oil, it needs to run cooler. These differences would not be possible without split, or dual, cooling systems and the use of additional, electrically operated ‘on demand’ e-pumps to supplement, and in some applications, replace, the system’s mechanical pump.

As a result, to support its aftermarket customers globally and to provide installers with the service and repair solutions they need, Dayco has introduced a wide range of main and auxiliary e-pumps to its thermal management program. The company’s water pump offering, which is manufactured to OE equivalent standards, is under continuous development and reflects the requirements of an ever-changing market.

To underpin the e-pump offering, Dayco also provides, technical advice, fitting tips and comprehensive cataloging support.
