The global trend of downsizing engines while keeping high power has increased to a proliferation of turbocharged engines. These smaller engines generate more heat than naturally aspirated ones, requiring advanced cooling solutions. Electric water pumps efficiently handle these higher cooling demands of these engines by operating at variable speeds, providing tailored thermal regulation under different conditions.
Electric water pump manufacturers are expanding their aftermarket portfolio. For instance, in March 2024, Schaeffler expanded its aftermarket portfolio with electric auxiliary water pumps under its INA brand. These pumps are essential for managing the temperature of modern combustion engines, hybrids, and electric vehicles. Schaeffler's Automotive Aftermarket division offers these pumps, meeting high OEM standards. This solution covers over 50 million vehicles from various well-known manufacturers, benefiting owners of combustion engines, hybrids, and electric vehicles.
Additionally, manufacturers are focusing on developing advanced electric water pumps that are lightweight, durable, and energy efficient. Innovations such as brushless motors, integrated control systems, and compact designs enhance overall vehicle efficiency while offering superior cooling performance. These advancements have accelerated the adoption of electric water pumps across various automotive applications.
Electric water pumps cost more than traditional mechanical pumps as it uses advanced parts such as high-performance motors, control systems, and electronic circuits. These costs increase due to specialized manufacturing and testing. Integrating these pumps into existing vehicles requires changes to engine design and software, raising development costs. This is a significant issue for automakers and markets with tight budgets, limiting adoption in regions that prefer affordable options over advanced technology.
