DC48V 275L_min 30m Head Centrifugal Shielded Electric Pump for In row CDU Applications

The OWP-BL2000H-D3-1 is a horizontal single-stage centrifugal shielded electric pump designed exclusively for In row CDU systems.

It operates on DC48V power, delivering 275L/min flow rate at 30m head to meet high-density cooling demands.

With IP67 protection and ≥40,000h lifespan, it ensures reliable operation in harsh data center environments.

The pump integrates brushless permanent magnet synchronous motor technology for efficiency and zero-leakage performance.

In row CDU systems require stable coolant circulation for multiple server racks, facing critical technical challenges.

Traditional pumps suffer from leakage risks due to mechanical seals, endangering data center equipment and safety.

Fluctuating flow rates lead to uneven cooling, affecting server performance and lifespan.

Harsh operating conditions (wide temperature ranges, high humidity) demand robust environmental adaptability.

Energy inefficiency and short service lives of conventional motors increase operational costs significantly.

• Centrifugal shielded design eliminates leakage by integrating rotor and impeller in a sealed pressure chamber.
• Brushless permanent magnet synchronous motor achieves high efficiency (up to 82% peak efficiency) and extended lifespan.
• Constant flow control maintains stable cooling performance even under varying system loads.
• Comprehensive protection mechanisms (reverse polarity, dry run, overvoltage, overcurrent, overload, overtemperature) prevent pump damage.
• Wide operating voltage (DC42~58V) and temperature ranges (-40℃~60℃ ambient) adapt to extreme working conditions.
• RS485 communication enables seamless integration with CDU control systems for remote monitoring.

The OWP-BL2000H-D3-1 is optimized for In row CDU (Coolant Distribution Unit) applications in data centers.

It provides continuous, leak-free coolant circulation for multiple server racks in row-based cooling architectures.

The φ64mm quick-install chuck enables fast, secure pipeline connections, reducing installation time.

Constant flow control ensures uniform heat dissipation across all servers in the row.

IP67 protection and wide temperature tolerance suit the demanding data center environment.

Cast aluminum wetted parts ensure compatibility with deionized water and antifreeze media.

The pump adopts an integrated "motor + pump" structure with a sealed pressure chamber.

A thin-walled shield sleeve isolates the stator from the rotor and medium, eliminating leakage points.

The brushless permanent magnet synchronous motor converts electrical energy to mechanical energy with minimal loss.

Rotation of the impeller creates centrifugal force, driving coolant flow at the specified head and rate.

Internal coolant circulation lubricates bearings and cools the motor, preventing overheating.

Built-in sensors monitor operating conditions, triggering protective actions when anomalies occur.

RS485 communication transmits real-time data to the CDU control system for dynamic adjustments.

1. Calculate Heat Dissipation Capacity

   Follow the 1.5L/min per 1KW heat dissipation rule: 275L/min ÷ 1.5L/(min·KW) ≈ 183KW.

   The pump suits In row CDU systems supporting hosts with total heat dissipation ≤183KW.

2. Verify Voltage Compatibility

   Ensure the CDU’s power supply matches the pump’s DC42~58V operating range.

   Prioritize systems with stable DC48V output for optimal performance.

3. Check Medium Requirements

   Confirm the cooling system uses deionized water or antifreeze (compatible with cast aluminum parts).

   Avoid corrosive media that may damage wetted components.

4. Assess Environmental Conditions

   Validate ambient temperature (-40℃~60℃) and humidity (5~95%) fit the installation site.

   Ensure altitude does not exceed 3000m to maintain performance.

5. Evaluate System Pressure

   The pump operates within -0.9Bar~10Bar; match with the CDU’s pressure specifications.

   Consider pressure fluctuations for long-term reliability.
