275L/min 30m Head DC48V Horizontal Centrifugal Shielded Pump_ Reliable Cooling Solution for CDU

The OWP-BL2000H-D3-1 is a horizontal single-stage centrifugal shielded electric pump designed exclusively for Coolant Distribute Units (CDU).

It operates with deionized water or antifreeze, delivering 275L/min flow at 30m head under DC48V power supply.

Integrating brushless permanent magnet synchronous motor technology, this pump ensures zero leakage, high efficiency, and long-term stability—critical for CDU system performance.

Its robust design meets IP67 protection and wide environmental adaptability, making it a trusted choice for precision cooling.

Modern CDU systems face escalating demands for heat dissipation with the rise of high-power computing and industrial equipment.

Leakage risks from traditional pumps threaten sensitive components, as CDU circulates critical cooling media.

Fluctuating flow rates lead to uneven cooling, reducing system efficiency and shortening component lifespan.

Extreme operating conditions (temperature, humidity, pressure) and lack of protective mechanisms further increase downtime risks.

Additionally, energy consumption and maintenance costs remain major concerns for CDU operators.

The centrifugal shielded structure eliminates leakage by integrating pump and motor in a sealed cavity with static seals .

Brushless permanent magnet synchronous motor delivers over 40,000 hours of service life with superior energy efficiency .

Constant flow control maintains stable cooling performance, adapting to dynamic heat loads .

Comprehensive protection features (reverse connection, dry running, overvoltage, overcurrent, overload, overtemperature) prevent pump damage.

IP67 rating ensures dust-tight and temporary submersion protection, suitable for harsh environments .

RS485 communication enables centralized monitoring and coordinated operation .

This pump is engineered as the core power component for CDU systems, responsible for circulating deionized water or antifreeze.

It ensures uniform coolant distribution across servers, industrial machinery, or high-power equipment in CDU setups.

The 275L/min flow rate and 30m head meet the high-demand cooling requirements of modern CDU architectures.

With wide temperature adaptability (-40℃~60℃ ambient, -30℃~60℃ medium), it performs reliably in diverse CDU operating environments.

Cast aluminum water-contact parts resist corrosion from cooling media, ensuring compatibility and long-term service .

RS485 communication integrates seamlessly with CDU control systems for real-time monitoring and adjustment .

The pump adopts an integrated motor-pump design with rotor and impeller on the same shaft .

Shield sleeves isolate the stator from the medium, enabling leak-free operation while transmitting magnetic force .

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

Constant flow control is achieved via electronic regulation, maintaining preset flow rates regardless of pressure fluctuations .

Internal medium circulates through gaps to cool the motor and lubricate bearings, preventing overheating .

Protection mechanisms activate automatically: dry running protection stops the pump when no medium is detected, while overtemperature protection triggers at critical heat thresholds.

Calculate heat dissipation requirements: Follow the 1.5L/min per 1KW rule—this pump’s 275L/min flow supports up to 183KW (275/1.5) heat load.

Select it for CDU systems matching or below this power range to ensure effective cooling.

2. Verify voltage compatibility: Ensure the CDU’s power supply falls within DC42~58V; use a stable DC48V source for optimal performance.
3. Confirm medium type: The pump is compatible only with deionized water and antifreeze—avoid corrosive or viscous media.
4. Check environmental conditions: Ensure operating temperature (-40℃~60℃), humidity (5~95%), and altitude (≤3000m) match the application site.
5. Evaluate system pressure: Confirm the CDU’s working pressure is within -0.9Bar~10Bar to prevent pump failure.
