Product Description

Electric Water Pump Driven by BLDC Motor with Long Life Span for Electric Vessels' Battery Cooling

High-Efficiency Brushless DC Pump for Electric Boat Battery & Engine Coolant Circulation

Model: OWP-BL43-200 - Designed specifically for electric boat battery cooling and engine coolant circulation, this brushless DC pump delivers reliable performance to protect critical marine systems from overheating. Its engineering excellence and robust build make it an ideal choice for marine applications where durability, efficiency, and safety are non-negotiable.

Key Advantages for Marine Use

Superior Efficiency: Verified by professional electromagnetic theory design, its motor efficiency is 3-5% higher than competing pumps. Professional software-driven hydraulic simulation optimizes the match between the impeller and volute, ensuring higher hydraulic efficiency to maintain steady coolant flow for batteries and engines.
Extreme Durability: Built with automotive-grade electronic components, it withstands harsh marine environments (humidity, vibration, temperature fluctuations). Compliant with IP67 waterproof standards (per EN60529), it features an aluminum pump housing, SUS 304 stainless steel screws, and a PPA GF motor winding frame—all resisting corrosion and wear. It offers a service life of over 20,000 hours at rated voltage (24VDC) and 36℃ (86°F) ambient temperature.
Comprehensive Protection: Equipped with constant flow control, reverse polarity protection, dry running protection, over-voltage/over-current protection, and overload/over-temperature protection. These features prevent pump damage and shield connected battery/engine systems from failures.
Energy-Saving & Quiet Operation: Powered by a high-efficiency brushless DC motor, it reduces power consumption (critical for electric boats' battery life) while operating at ≤60dB—minimizing noise disruption on board.
