OWP-BL43-200 High-Efficiency Fixed-Speed Electric Water Pump: Ideal for Glycol Circulation
The OWP-BL43-200 Fixed-speed Electric Water Pump is engineered specifically for circulating glycol and other coolants, making it a critical component for maintaining steady temperatures in marine battery systems and engines. Designed to thrive in harsh marine conditions, it ensures reliable coolant flow to prevent overheating, supporting the smooth operation of electric and hybrid boats.
Key Advantages for Marine Applications
Superior Efficiency: Backed by professional electromagnetic design, its motor efficiency exceeds competing pumps by 3-5%. Advanced hydraulic simulation optimizes the impeller-volute match, boosting hydraulic efficiency to sustain consistent coolant flow for batteries and engines.
Extreme Durability: Constructed with automotive-grade electronic components, it resists humidity, vibration, and temperature fluctuations. Compliant with IP67 waterproof standards (per EN60529), it features an aluminum housing, SUS 304 stainless steel screws, and a PPA GF motor winding frame—all ensuring corrosion and wear resistance. It delivers over 20,000 hours of service life at 24VDC (rated voltage) 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 (vital for extending electric boats’ battery life) and operates at ≤60dB, minimizing on-board noise disruption.
