Compact BLDC Electric Coolant Pump - Optimized for PV Inverter & Industrial UPS Liquid Cooling Systems

The OWP-BL93-201 Electric Coolant Pump is a high-performance fluid circulation solution crafted to address the thermal management needs of PV inverters and industrial UPS systems. Leveraging permanent magnet brushless DC technology and a rugged design, it delivers consistent flow and pressure under varying operating conditions, ensuring reliable heat dissipation for critical electronic components.

• Permanent Magnet BLDC Configuration: Features a compact footprint and low power consumption, making it ideal for space-constrained PV inverters and UPS systems while reducing energy usage.
• Multi-Layer Protection Functions: Integrates safeguards against reverse polarity, overvoltage, overcurrent, dry running, and overtemperature to prevent component damage and ensure operational safety.
• Long-Lasting Shaft Assembly: Utilizes ultra-durable friction pair materials for the shaft system, minimizing wear during high-speed operation and extending the pump’s service life beyond 20,000 hours.
• Centrifugal & Shielded Hybrid Structure: Combines centrifugal pumping efficiency with a shielded design to isolate the motor from the circulating medium, enhancing leak resistance and operational stability.
• Lifetime Maintenance-Free Operation: Sealed construction and premium material selection eliminate the need for regular upkeep, reducing downtime and operational costs for industrial applications.
• Closed Impeller Design: Incorporates a precision-machined closed impeller to maximize hydraulic efficiency, minimize energy loss, and maintain low noise levels (≤45dB) during operation.

The OWP-BL93-201 Electric Coolant Pump is specifically designed for liquid cooling systems in PV inverters and industrial UPS units. With a rated power of 100W, maximum flow rate of 2800L/H, and 11M lift head, it efficiently circulates cooling media to dissipate heat generated by high-power electronic components. Compatible with glycol-water mixtures, dielectric oil, and electronic fluorinated solutions, it operates reliably across a wide temperature range (-40℃ to 85℃), adapting to harsh industrial environments. The IP68 protection grade ensures suitability for both indoor and outdoor installations, while its fixed-speed operation provides consistent flow for stable thermal management. This pump directly enhances the performance and lifespan of PV inverters and industrial UPS systems by maintaining optimal operating temperatures, reducing the risk of overheating-related failures.
