OWP-BL2000H-D3-1 DC48V Shielded Centrifugal Pump: Ideal for Liquid-to-Air Cooling Systems & CDU

The OWP-BL2000H-D3-1 is a horizontal single-stage centrifugal shielded electronic pump designed for Liquid-to-Air cooling systems and CDU applications.

It delivers 275 L/min flow rate at 30m head with DC48V power supply, featuring IP67 protection and cast aluminum wetted parts.

This pump integrates brushless permanent magnet synchronous motor technology, ensuring high efficiency and a service life of over 40,000 hours.

It supports deionized water and antifreeze media, with multiple protection functions for reliable operation in harsh environments.

Liquid-to-Air cooling systems and CDUs face critical challenges in high-power heat dissipation scenarios.

Leakage risks from traditional pumps threaten system safety, especially when handling expensive or sensitive cooling media.

Inefficient motors lead to high energy consumption and shortened service life, increasing operational costs.

Extreme temperature fluctuations (-40℃~60℃) and humidity (5~95%) demand robust environmental adaptability.

Lack of comprehensive protection functions often results in pump damage from dry running, overvoltage, or reverse connection.

The centrifugal shielded design eliminates leakage risks by integrating rotor and impeller in a sealed chamber.

Brushless permanent magnet synchronous motor achieves higher efficiency than conventional motors, reducing energy loss.

Constant flow control maintains stable cooling performance regardless of system pressure changes.

Multiple protection mechanisms prevent pump failure: reverse connection, dry running, overvoltage, overcurrent, overload and overtemperature protection.

Cast aluminum wetted parts offer excellent corrosion resistance and structural stability.

IP67 protection rating ensures reliable operation in dusty, humid, or water-exposed environments.

• The pump’s 275 L/min flow rate and 30m head efficiently circulate coolants in high-power heat exchange systems.
• Wide temperature adaptation suits both indoor and outdoor Liquid-to-Air heat dissipation equipment.
• IP67 protection resists dust and moisture, suitable for industrial and data center cooling environments.
• Quick-connect chuck design simplifies installation, disassembly and routine loop maintenance.

• Stable constant flow control ensures uniform coolant distribution across multiple cooling nodes.
• RS485 communication supports real-time monitoring and remote system linkage.
• Working pressure range meets the operation requirements of high-density liquid cooling CDU equipment.
• Cast aluminum contact parts operate stably with deionized water or antifreeze coolant.

• The shielded centrifugal structure separates the motor stator from coolant to realize zero-leakage operation.
• The brushless permanent magnet synchronous motor converts electric energy into rotating mechanical energy efficiently.
• High-speed rotating impeller generates centrifugal force to drive continuous coolant circulation.
• Built-in constant flow algorithm stabilizes flow output under varying system resistance.
• RS485 interface realizes real-time data upload and remote parameter adjustment.
• Built-in detection circuits activate protective shutdown once abnormal operating conditions are detected.

1. Confirm Host Heat Dissipation Power

   Adopt the standard ratio: 1.5 L/min flow corresponds to 1 KW heat dissipation capacity.

   With the maximum available flow of 275 L/min, the pump can support hosts with heat load up to around 183 KW.

   Select OWP-BL2000H-D3-1 for Liquid-to-Air systems or CDUs whose total heat dissipation ≤ 183 KW.

2. Confirm Power Supply Condition

   Check that the on-site power supply stays within DC42V ~ 58V working voltage range.

   Avoid excessive voltage fluctuation which may trigger built-in electrical protection.

3. Verify Coolant Medium

   This pump is designed for deionized water and antifreeze only.

   Confirm the coolant temperature stays within -30℃ ~ 60℃ during long-term operation.

4. Check Environmental Limits

   Verify ambient temperature, humidity, altitude and system pressure match product specifications.

   Do not use the pump beyond defined environmental boundaries to avoid shortened service life.

5. Confirm Interface and Installation Space

   Match pipeline layout with φ64mm quick-install chuck interface.

   Reserve sufficient installation space for the 4.5kg horizontal mounted pump.
