The Electric Water Pump OWP-BL43-200 is a high-reliability, efficient solution tailored for thermal management, with a strong focus on energy storage systems. Operating on a single-stage centrifugal structure paired with magnetic force transmission (shield pump design), it uses a high-efficiency brushless DC motor (service life >20,000 hours) to drive fluid circulation. This motor reduces power consumption while integrating multiple protections: reverse polarity, dry running, over-voltage/over-current, and overload/over-temperature safeguards, ensuring safe operation even in harsh conditions. PWM speed control enables precise flow adjustment, and its IP67 waterproof rating (per EN60529) supports use in wet or dusty environments.
Its core application is energy storage thermal management systems, where it regulates coolant flow to maintain optimal temperatures for battery energy storage units—preventing overheating, extending battery life, and ensuring stable energy output. It also adapts to EV motor cooling, high-power EV charging station cooling, and industrial cooling (e.g., data center immersion cooling), but excels in energy storage due to its wide operating temperature range (-40℃ to +85℃) and constant flow control.
