Electrification of automotive water pumps and rising demand for auxiliary coolant pumps

Demand for electric water pumps—both main and auxiliary—is expected to grow strongly with increased sales numbers for mild hybrids, full HEVs, ICEs with stop-start and forced induction, and BEVs. The business for main and auxiliary electric water pumps is expected to grow to USD1.6 billion and USD1.5 billion, respectively, by 2023.

The internal combustion engine (ICE) is the dominant propulsion system technology driving the global transportation industry and has remained so for the better part of the century since the dawn of automobile. The ICE generates the power required to drive the wheels using the energy derived from the combustion of fuel (gasoline/diesel or alternative fuels) within the cylinders. During the combustion process, the burning gases within the engine cylinder can reach a temperature of up to 2500°C based on the engine—beyond the melting point of the materials that make up the cylinder block and head of the engine. The heat, if not managed, can lead to several critical issues
