1. High Efficiency & Low Noise: Equipped with a closed impeller design, the OWP-BL3000H-A3-1 achieves large flow rates while optimizing energy efficiency and minimizing operational noise—meeting the ≤70dB noise standard at rated load for quiet operation.
2. Compact & Energy-Saving: As a permanent magnet brushless pump, it features a space-saving footprint and low power consumption, reducing both installation space requirements and long-term operational costs.
3. Durable Construction: The shaft assembly utilizes ultra-high-life friction pair materials, supporting a service life exceeding 20,000 hours. With IP67 protection and F-class insulation, it withstands extreme temperatures (-40℃ to 85℃) and humid environments (＜90%RH) for reliable performance.
4. Superior Sealing Performance: Tested at 0.35MPa, the pump ensures minimal leakage (＜0.8mL/min), preventing fluid loss and maintaining system integrity in critical circulation applications.

The OWP-BL3000H-A3-1 Electronic Coolant Pump is specifically designed to meet the rigorous demands of central air conditioning cooling water circulation systems, where consistent flow, pressure stability, and energy efficiency are paramount. Its rated power of 3000W and impressive flow capacity (400L/min with ≥25m head) enable efficient heat transfer across large commercial or industrial HVAC systems, ensuring optimal cooling performance even during peak load conditions. The pump’s wide operating voltage range (AC380V±15%) and temperature tolerance (-40℃ to 85℃ for both ambient and medium) make it adaptable to diverse environmental conditions, from cold climates to high-temperature industrial settings.

In central air conditioning systems, the OWP-BL3000H-A3-1’s closed impeller design enhances water circulation efficiency, reducing energy waste and lowering operational costs for building managers. The permanent magnet brushless technology not only minimizes power consumption but also contributes to the pump’s extended 20,000-hour service life, reducing maintenance frequency and downtime. With IP67 protection, the pump is safeguarded against dust and water ingress, ensuring reliable operation in damp HVAC mechanical rooms. The low noise level (≤70dB) is particularly beneficial for commercial buildings such as offices, hotels, and shopping malls, where quiet operation is essential for occupant comfort.

Additionally, the pump’s F-class insulation and strict leakage control (＜0.8mL/min) comply with industry safety standards, providing peace of mind for system integrators and facility managers. Whether used in new central air conditioning installations or as a replacement for outdated pumps, the OWP-BL3000H-A3-1 Electronic Coolant Pump delivers consistent performance, energy efficiency, and durability—making it a trusted solution for maintaining optimal cooling water circulation in commercial and industrial buildings.
