Electric Coolant Pump Market Size and Trends

The global electric coolant pump market size was valued at US$ 328.3 million in 2023 and is expected to reach US$ 912.7 million by 2030, grow at a compound annual growth rate (CAGR) of 15.73% from 2023 to 2030. Electric coolant pumps are used in internal combustion engines and electric vehicles to circulate engine coolant and maintain optimal temperature. Key advantages include higher efficiency, reduced emissions, and lower parasitic losses compared to mechanical pumps. Major drivers include stringent emission norms, electrification of vehicles, and advancements in pump technology.

The electric coolant pump market is segmented by type, vehicle type, application, propulsion type, technology and region. By vehicle type, the passenger cars segment is expected to dominate the market owing to the rising production of economy and mid-priced passenger vehicles globally.

Electric Coolant Pump Market Drivers:

Stringent Emission Regulations: Government regulations to curb emissions are a major factor driving growth in the electric coolant pump market. With rising concerns over environmental pollution, regulations on emission control have become more stringent across developed and developing nations. For instance, the implementation of Euro 6d norms in Europe has compelled automakers to adopt advanced technologies, including electric coolant pumps. Electric pumps offer higher efficiency and eliminate belt drive losses from engine accessory drive systems. Their adoption helps Original Equipment Ms meet tightening CO2 emission targets. The introduction of BS-VI norms in India has also accelerated the installation of electric pumps in vehicles. Thus, increasingly stringent emission control regulations are stimulating the adoption of these pumps. For instance, passenger cars and vans are major contributors to greenhouse gas emissions in the EU, accounting for roughly 12% and 2.5% of total CO2 emissions, respectively. To address this issue, stricter CO2 emission performance standards were implemented for new vehicles in 2020. This change has already yielded significant results, with average CO2 emissions from new cars dropping by 12% in 2020 and an additional 12.5% in 2021.
Increasing Production of Hybrid and Electric Vehicles: The rising trend of vehicle electrification provides significant opportunities for electric coolant pump manufacturers. These pumps find wide application in hybrid, plug-in hybrid, and battery electric automobiles. They play a critical role in the thermal management of HV batteries and power control units in electrified powertrains. According to the International Energy Agency (IEA), the global electric car stock hit 10 million in 2020, a 43% increase over 2019. Moreover, hybrid electric vehicles accounted for over 5 million sales. The rapidly growing production of hybrid and electric cars and commercial vehicles will continue to propel the electric coolant pump market.
Advancements in Pump Technology: Original Equipment Manufacturers are increasingly focused on improving the efficiency and performance of electric coolant pumps. Automotive suppliers are developing innovative pump designs integrated with advanced Brushless DC motors and intelligent control units. Unlike conventional pumps, brushless pumps enable variable speed operation, resulting in reduced power consumption. Intelligent pumps can adjust the coolant flow rate based on driving conditions and cooling requirements. They can detect failures through integrated sensors and protect the engine. Such technological advancements are driving adoption among automakers.
Growing Adoption in Combustion Engine Vehicles: Besides the electrification trend, electric pumps are also gaining steady adoption in traditional internal combustion engine vehicles. Eliminating accessory drive belts and pulleys helps reduce parasitic losses and improve fuel efficiency. Engine downsizing is another key factor that increases the cooling demand, thereby driving the integration of electric pumps. As reducing CO2 emissions remains a key focus for automakers, demand for next-generation electric coolant pump will continue to grow through 2030.

Electric Coolant Pump Market Trends:

Development of High Efficiency Pumps: Manufacturers are increasingly focusing on improving pump efficiency to ensure reduced power consumption and long-term reliability. They are using electromagnetic designs and innovative brushless motors to achieve higher efficiency levels of over 90% at high speeds. Integration of variable speed drives also contributes to high efficiency across the operating range. Such advancements are resulting in widespread adoption among OEMs. High-efficiency pumps reduce CO2 emissions and help meet tightening vehicle emission norms.
Integration of Sensors for Diagnostics: Incorporation of sensors and electronics within electric coolant pumps is an emerging trend enabling advanced diagnostics, monitoring, and control functions. For instance, pressure, temperature, and speed sensors provide inputs to the integrated Electronic Control Unit. They enable condition monitoring capabilities, including early failure detection. Diagnostic data can be accessed via in-vehicle networks such as Controller Area Network This allows for proactive maintenance and reduces vehicle downtime. The sensor integration also aids in building smart pumps.
Growing Adoption of Seal-less Magnetic Pumps: Seal-less or magnet drive pumps that do not require shaft seals are gaining increasing prominence in electric coolant pump applications. Unlike traditional pumps, magnetic drive pumps prevent leakages caused by seal wear. They offer maintenance-free operation and ability to run dry without damage. BMW, Volkswagen, and Audi are some OEMs using seal-less magnetic pumps. Their adoption helps improve reliability and longevity while reducing costs associated with leakage issues. For instance, in November 2021, HMD Kontro, a leading specialist in magnetic drive sealless pumps, launched a new pump specifically designed for demanding hydrofluoric acid (HF) alkylation applications. Developed in collaboration with HF Unit Operators and UOP (Honeywell), the leading licensor of HF alkylation technology, this innovative pump features a high-integrity C22/C276 casing and offers exceptional leak-free performance.
Usage of Advanced Materials for Lightweighting: Lightweighting continues to be a key focus area for automotive cooling system suppliers in order to enhance fuel efficiency. Manufacturers are adopting advanced materials such as aluminum, plastics, and composites to reduce pump weight and dimensions. Thermoplastics like PBT can withstand high temperatures up to 200°C. The use of carbon fiber reinforced plastics also minimizes weight. Schaeffler a manufacturer of rolling element bearings and KSPG manufacturer of pumps and pumping equipment, offers plastic housing pumps, while Rheinmetall uses an alloy containing 70% aluminum. Lightweighting improves mechanical performance and heat resistance.
