Dayco Electric Water Pumps

Electronic Water Pumps from Dayco

Dayco is an original equipment (OE) power transmission specialist that has been consistently growing its aftermarket programme to allow it to provide workshops with an ever wider range of high quality components that they and their customers can rely on.

Thermal management is one of the product groups that Dayco has put a particular focus on, as there is a natural association with its core belt drive systems strengths, and water pumps are central to this category. Although this initially began with mechanically driven pumps, which feature in more than 300 of its water pump kits, (belt, tensioners, idlers and pump), reflecting the developments in automotive design and the huge growth in, first hybrid and now pure electric drivetrains, electric water pumps (e-pumps) have become a growing presence in the aftermarket, as these vehicles are now entering the independent workshop.

For electric vehicles and many hybrid applications, e-pumps are the only solution able to effectively ensure the correct temperature management of the vehicle’s inverters and battery packs, for example. However, vehicle manufacturers globally are under huge pressure to reduce emissions and maximise the efficiencies of their combustion engine powered models and with these, reaching and maintaining different operating temperatures around the engine is a necessity.

To optimise 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.

So, to provide workshops with the service and repair solutions they need, Dayco introduced a wide range of e-pumps, which are manufactured to OE equivalent standards, and reflect the requirements of an ever- changing market.

In addition to primary e-pumps, and reflecting the fact that some modern applications can have up to four e-pumps undertaking individual and collective operations, the Dayco range also includes auxiliary e-pumps and cooling system support e-pumps.

Whatever the pump used in the cooling system, effective thermal control is still governed by engine thermostats, and, with even stricter future emissions regulations that will require engines to operate at 10% higher temperatures and increased pressure to fall within the limits, as well as to minimise fuel combustion, these often-overlooked components are growing in number and complexity.

So, although the traditional naked version, which was introduced in the 1920s, remained almost unchanged for the rest of the century, today it’s a different story with integrated thermostat housings and MAP thermostats that are controlled and activated via the vehicle’s ECU. Therefore, only OE quality products, such as those supplied by Dayco, should be used when they are replaced, as inaccuracies of more than plus or minus two degrees centigrade will have a considerable effect on the level of emissions emitted.
