OWP-BL3000H-A3-1 centrifugal PMSM electronic Coolant pump for Coolant Distribute Units (CDU)

1. Specifications

2. Application

This product is exclusively tailored for Coolant Distribute Units (CDU), serving as the key power unit for coolant circulation in liquid cooling systems. The technical parameters of the OWP-BL3000H-A3-1 are precisely matched to the operational demands of CDU:

The compatibility with deionized water and antifreeze aligns with the common coolant types used in CDU systems, ensuring chemical stability and avoiding component corrosion. The wide temperature range (-40℃~85℃) enables reliable operation in both low-temperature outdoor installations and high-temperature industrial environments where CDU systems are typically deployed.

With a system pressure range of -0.9Bar to 10Bar, the pump adapts to the pressure fluctuations commonly encountered in CDU circulation loops, maintaining consistent flow output. The IP67 protection rating prevents dust and water ingress, a critical requirement for CDU units operating in harsh industrial settings.

The φ64mm quick-install chuck design facilitates rapid assembly and disassembly during CDU system installation or maintenance, improving operational efficiency. Additionally, the RS485 communication interface allows for real-time monitoring and control of the pump’s operating status, integrating seamlessly with CDU system management platforms.

3. Main Points & Industry Demands

CDU systems require coolant circulation solutions that prioritize heat dissipation efficiency, system adaptability, and long-term stability to ensure continuous operation of the associated cooling infrastructure. High heat load handling is a core demand, as CDU units are tasked with dissipating significant heat from industrial equipment or data center servers.

This necessitates a pump with sufficient flow rate and head to deliver coolant promptly across the circulation loop. Adaptability to diverse operating conditions is another key requirement, as CDU systems may be deployed in varying altitudes, humidity levels, and temperature extremes.

Stability and reliability are non-negotiable, as pump failures can lead to CDU system downtime and subsequent equipment overheating. Leak-proof performance is critical to protect sensitive components within the CDU and surrounding infrastructure.

Energy efficiency is also a growing industry focus, driving the demand for low-power-consumption pumps that reduce overall system operating costs. The OWP-BL3000H-A3-1 addresses these demands through its technical parameter configuration and structural design, aligning with the core needs of CDU applications.

4. Product Advantages as Core Solutions

• Centrifugal Shielded Pump Structure → Leak-Proof Advantage → Solution for CDU System Integrity: The centrifugal shielded design eliminates leakage risks, a direct response to the CDU industry’s need to prevent coolant loss and protect sensitive system components. This structural parameter ensures that the pump maintains a sealed operation, avoiding downtime caused by leaks and safeguarding the CDU’s cooling efficiency.
• Permanent Magnet Brushless Synchronous Motor → Small Size & Low Power Consumption → Solution for CDU Space & Energy Requirements: The adoption of a permanent magnet brushless synchronous motor (a key technical parameter) results in a compact footprint and reduced power consumption. This addresses the CDU’s need for space-efficient components (often installed in confined equipment rooms) while lowering energy costs, aligning with industry demands for energy-efficient solutions.
• Closed Twisted Impeller → High Flow Rate, High Efficiency & Low Noise → Solution for CDU Heat Dissipation & Operational Comfort: The closed twisted impeller design (a core structural parameter) enables the pump to achieve 400L/min flow rate at 25m head with high operational efficiency. This directly meets the CDU’s requirement for efficient heat dissipation by ensuring adequate coolant circulation, while the ≤70dB noise level (measured 1m from the pump) enhances the operational environment, particularly in indoor CDU installations.
• Ultra-High-Life Friction Pair Material → ≥20000h Service Life → Solution for CDU Long-Term Stability: The use of ultra-high-life friction pair material in the shaft system (a material parameter) guarantees a service life of at least 20000h. This addresses the CDU industry’s demand for long-term reliable operation, reducing maintenance frequency and downtime, and ensuring the pump can sustain continuous service in 24/7 CDU applications.

5. Operational Mechanism

The OWP-BL3000H-A3-1 operates based on the principle of centrifugal force generated by impeller rotation. When powered by the AC380V supply, the permanent magnet brushless synchronous motor drives the closed twisted impeller to rotate at high speed.

This rotation creates a pressure difference between the pump’s inlet and outlet: the low pressure at the inlet draws coolant (deionized water or antifreeze) into the pump chamber, while the centrifugal force generated by the impeller propels the coolant outward, generating the required head (up to 25m) to circulate the coolant through the CDU system.

The ultra-high-life friction pair material in the shaft system minimizes wear during high-speed rotation, extending the pump’s service life. The IP67 protection structure isolates the motor and internal components from external dust and moisture, ensuring stable operation in harsh environments.

The RS485 communication interface enables bidirectional data transmission between the pump and the CDU system controller, allowing for real-time monitoring of operating parameters (e.g., flow rate, temperature) and remote adjustments as needed. The φ64mm quick-install chuck facilitates secure and rapid connection to the CDU’s coolant pipelines, ensuring tight sealing and efficient fluid transfer.

6. Selection Guide

Based on the industry convention of 1.5L/min flow rate corresponding to 1KW heat dissipation capacity, the OWP-BL3000H-A3-1’s maximum flow rate of 400L/min (at 25m head) provides a reference for 适配 CDU host heat dissipation systems.

Calculating the approximate heat load range: 400L/min ÷ 1.5L/(min·KW) ≈ 266.7KW. This suggests the pump is suitable for CDU systems with a host heat dissipation capacity ranging from approximately 260KW to 270KW.

It is important to note that this range is for reference only. Actual 适配 depends on specific CDU system configurations, including pipeline length, resistance, coolant type, and operating temperature. For systems with higher pipeline resistance or different coolant properties, the effective flow rate may vary, and adjustments to the selection should be made based on detailed system requirements.

Users are advised to conduct a comprehensive assessment of their CDU system’s heat load, pressure loss, and installation constraints to confirm the pump’s suitability.
