Designed with industrial reliability in mind, the OWP-BL43-440T Electric Coolant Pump integrates advanced technologies to deliver exceptional performance. Its closed-type impeller ensures high pumping efficiency while minimizing operational noise, keeping the working environment quiet at ≤60dB. The permanent magnet brushless motor not only reduces the pump’s overall size for easy installation in space-constrained industrial setups but also lowers power consumption, aligning with energy-saving requirements. The shaft system adopts ultra-long-life friction pair materials, directly contributing to a service life exceeding 20,000 hours and reducing maintenance frequency. Featuring a centrifugal & shielded structure, the pump enhances operational stability and prevents media leakage. With PWM duty cycle speed regulation, users can precisely adjust the flow rate to match dynamic heat dissipation needs of industrial servo drives. Equipped with comprehensive protection functions—including reverse connection protection, overvoltage protection, overcurrent protection, dry running protection, and overtemperature protection—the pump safeguards both itself and the connected servo systems from potential damage, ensuring continuous operation. Boasting an IP68 rating, it offers superior waterproof and dustproof performance, making it suitable for harsh industrial environments.

The OWP-BL43-440T Electric Coolant Pump is specifically engineered for industrial servo drive heat dissipation in the industrial automation sector, a critical application where stable and efficient thermal management directly impacts equipment performance and lifespan. Industrial servo drives generate significant heat during high-speed, continuous operation, and improper heat dissipation can lead to reduced precision, frequent malfunctions, or even permanent damage to the drives. This pump addresses these challenges with its tailored specifications: the rated flow rate of 3000L/H at 20M head and maximum flow of 5000L/H ensures rapid circulation of cooling media (50-60% glycol + water, dielectric oil, or electronic fluorinated solution) to effectively absorb and dissipate heat from servo drive components. The 23M maximum lift head enables the pump to maintain consistent flow even in complex piping systems of industrial setups, while the 25mm outlet diameter facilitates smooth media transfer. Operating within a wide voltage range of 18-32VDC (rated at 24VDC) and supporting PWM speed regulation, the OWP-BL43-440T can adapt to varying power supply conditions and adjust cooling capacity in real time as the servo drive’s heat output changes—optimizing energy efficiency without compromising cooling effectiveness. The high/low-level fault feedback signal provides real-time status monitoring, allowing for prompt troubleshooting and minimizing downtime in automated production lines. With its -40℃ to 85℃ medium temperature tolerance, the pump performs reliably in extreme industrial environments, from cold storage automation facilities to high-temperature manufacturing workshops. Its IP68 protection and >20,000-hour service life ensure long-term, maintenance-free operation, reducing total ownership costs for industrial automation enterprises. Whether integrated into robotic arms, CNC machine tools, or automated conveyor systems, the OWP-BL43-440T Electric Coolant Pump delivers consistent, efficient heat dissipation to keep industrial servo drives running at peak performance.
