Shenhai HS-030-502C Electric Water Pump Assembly

The HS-030-502C is a 24V brushless magnetic drive electric water pump designed for thermal management of electric motors, controllers, and battery systems in new energy commercial vehicles. It features a sealed magnetic coupling eliminating shaft seals, ensuring zero leakage and extended service life in high-voltage coolant circuits. The pump housing utilizes high-strength ABS and metal construction for structural integrity and chemical resistance to ethylene glycol coolant mixtures. This assembly serves as a direct OEM replacement for Nanjing Kaivo NJL6809 electric buses and cross-references applications across Zhongtong, Jinlong (Golden Dragon), Haige (Ankai), Higer, and Kinglong bus platforms. The unit weighs approximately 4.0 kg and integrates standard flange mounting and electrical connectors for plug-and-play installation in OEM cooling modules.
