Hebei Nanfeng Automobile Equipment (Group) Co., Ltd., established in 1993, is a group company with six factories. As one of the main suppliers of new energy vehicle components in China and the designated supplier of Chinese military vehicles, Nanfeng has built a reputation for reliability. Its portfolio includes high-voltage coolant heaters, electronic water pumps, BTMS, electric air compressors, EPS, EHPS, electric air conditioning compressors, three-way valves, parking heaters, parking air conditioners, and plate heat exchangers.
A Proven Supplier of EV Electronic Water Pump Solutions
This broad portfolio allows OEMs to source multiple thermal management components from one experienced supplier. Nanfeng’s pumps are designed for demanding vehicle and energy storage applications, backed by military-grade quality standards.
Ev Coolant Pump Classification: Main and Auxiliary
Main EWPs handle coolant circulation in the engine, power battery, or electric drive main loop. Low-voltage (12 V/24 V) main pumps typically cover 300–600 W, while high-voltage platforms extend beyond 2.4 kW for intensive battery cooling during fast charging. Auxiliary EWPs serve turbocharger post-run cooling, heater circuits, auxiliary electric drive cooling, and transmission oil cooling, with ratings from 10 W to 280 W, split into small (10–70 W) and large (80–280 W) units.
EV Circulation Pump Voltage Platforms
12 V products serve ICE and mild-hybrid vehicles and certain auxiliary loops; 24 V platforms target commercial and heavy-duty applications; high-voltage EWPs cool BEV battery main loops, with isolation between low-voltage control and high-voltage drive sides for safety.
Automotive Electric Coolant Pump Platform Series
Nanfeng offers five series. The 1/3 Series (17–80 W, 12 V/24 V) serves HVAC, motor-controller, and battery thermal management for light and medium-duty NEV trucks. The 2/4 Series (80–180 W, 12 V/24 V) covers medium-duty trucks plus hydrogen fuel cell auxiliary cooling. The 6/7 Series (115–600 W, 24 V) addresses medium and heavy trucks, coaches, hydrogen fuel cell cooling, and energy storage thermal management units. The 8 Series (600–1,000 W, 24 V) targets heavy trucks and coaches over 12 m. The high-voltage platform (1.5–2.5 kW; DC 400–750 V high side, DC 9–32 V low side) serves the same heavy-duty and large-coach segments.
Electric Automotive Water Pumps: OEM Benefits and Integration Readiness
For OEMs, these pumps deliver on-demand cooling, reduced parasitic loss, over 20,000 hours of service life, multiple protections, low NVH, and IP67 or higher protection. As thermal management integration accelerates, Nanfeng’s platforms offer a reliable path from component selection to series production.
