New Energy Power parts water pump 1307010-C5189(5AH1YKRJ)

As a key part of NEV thermal management systems, the 1307010-C5189(5AH1YKRJ) water pump is responsible for precise, continuous coolant circulation to prevent overheating of high-power components. For EVs: it circulates coolant through the traction motor and inverter, dissipating heat generated during high-speed driving or rapid charging (which can raise component temperatures to 120°C+). For HEVs/PHEVs: it balances cooling between the internal combustion engine (ICE) and electric motor, switching flow priorities based on powertrain mode (electric-only vs. hybrid). For FCVs: it cools the fuel cell stack, maintaining its optimal operating temperature range (60-80°C) to ensure efficient hydrogen-electrolyte reaction. The pump’s variable-speed control (adjustable via NEV thermal ECU) enables real-time flow rate adjustment (from 5L/min to 30L/min), ensuring energy-efficient cooling—critical for extending NEV driving range by reducing parasitic power consumption

The 1307010-C5189(5AH1YKRJ) water pump features a NEV-optimized rugged structure built to withstand the unique harsh conditions of new energy power systems—including high voltage, frequent start-stop cycles, and long-term exposure to coolants (e.g., ethylene glycol-based or low-conductivity NEV-specific coolants). The pump housing is constructed from glass-fiber reinforced PPS (Polyphenylene Sulfide) or aluminum alloy (ADC12), offering excellent chemical resistance to coolants and heat resistance (operating temperature range: -40°C to 150°C). The internal impeller uses engineering plastic (PA66+GF30) with a precision-machined surface, minimizing flow resistance and ensuring long-term wear resistance (even after 10,000+ hours of operation). The motor assembly (for electric-driven variants) uses high-temperature-resistant enameled wire (rated for 180°C) and a sealed bearing system (IP6K9K waterproof/dustproof), preventing coolant intrusion and ensuring reliability in NEV underbody or powertrain-mounted locations

The 1307010-C5189(5AH1YKRJ) is calibrated with NEV-specific technical parameters to maximize cooling efficiency and energy savings. Its electrical system supports NEV common voltages: 12V/24V for low-voltage auxiliary systems or 48V/300V/600V for high-voltage direct-drive variants (compatible with EV/HEV powertrain architectures). The pump’s maximum flow rate (up to 35L/min) and head pressure (up to 50kPa) are optimized to meet the cooling demands of high-power NEV components (e.g., 200kW+ traction motors). It features a variable-speed control range (500-3000 RPM) with PWM (Pulse-Width Modulation) signal compatibility, allowing the NEV thermal ECU to adjust flow in 1% increments—ensuring precise temperature control while minimizing power consumption (typical power draw: 50-150W, 30% lower than fixed-speed pumps). Additionally, the pump’s noise level is ≤55dB (at 1m distance), meeting NEV cabin quietness requirements

The 1307010-C5189(5AH1YKRJ) water pump meets strict global NEV quality and safety standards to ensure reliability in new energy applications. It is manufactured in accordance with ISO/TS 16949 (automotive quality management system) and complies with NEV-specific standards: IEC 60664 (insulation coordination for high-voltage systems) for high-voltage variants, and GB/T 18384 (safety requirements for EVs) for Chinese-market models. Each unit undergoes 100% factory testing, including: 1) Performance testing (flow rate, head pressure, speed control accuracy); 2) Environmental testing (temperature cycling, humidity, vibration per ISO 16750-3); 3) Durability testing (10,000-hour continuous operation simulation, equivalent to 200,000km NEV driving); 4) Electrical safety testing (insulation resistance, dielectric strength for high-voltage variants). To support NEV manufacturers and repair facilities, the pump comes with a 24-month/60,000km warranty and access to technical support—including coolant compatibility guidance and high-voltage safety installation training
