Product Specification

OWP Series Electric Coolant Pump for Data Center GPU Array Liquid-cooled 

# OWP-D-250LT-24-P38 High-Efficiency BLDC Coolant Pump: Specs, Uses & Advantages

The OWP-D-250LT-24-P38 is a industrial-grade brushless DC (BLDC) coolant pump engineered for high-performance thermal management. Built to withstand extreme conditions, it is a top choice for EVs, data centers, and industrial systems requiring reliable fluid circulation—addressing global demand for energy-efficient, long-lasting cooling solutions.

## Working Principle

This pump operates as a **single-stage centrifugal pump** with **magnetic force transmission** (shield pump structure), eliminating leakage risks and ensuring sealed performance. Its high-efficiency BLDC motor reduces power consumption while delivering consistent flow, supported by professional electromagnetic theory design for optimal energy use. Key protections include: constant flow control, reverse polarity protection, dry running protection, and over-voltage/current/load/temperature safeguards—preventing damage in harsh operations. PWM speed regulation allows flexible flow adjustment, adapting to dynamic cooling needs, while an IP67 waterproof rating (per EN60529) ensures dust and water resistance.

## Key Applications

The OWP-D-250LT-24-P38 is versatile across thermal management scenarios, including:

- Electric Vehicle (EV) systems: Motor cooling, controller cooling, battery thermal management, and high-power charging station cooling

- Data & computing: Immersion cooling, large-scale GPU cooling, and supercomputer cooling

- Industrial & energy: Fuel cell cooling, battery energy storage (BESS) cooling, glycol circulation boosting, and industrial cooling systems

- Telecommunications: Communication base station cooling

- Automotive: Turbocharger intercooler circulation and antifreeze circulation

## Core Advantages

What sets this pump apart from competitors:

1. **Higher efficiency**: 3-5% better motor efficiency (via professional electromagnetic verification) and optimized hydraulic performance (via simulation-based impeller/volute matching).

2. **Extreme durability**: Automotive-grade electronic components resist harsh environments; >20,000-hour service life (at rated voltage and 36℃ ambient temperature).

3. **Wide adaptability**: Handles media like 50-60% glycol-water mixtures, dielectric oil, and electronic fluorinated solutions; operates at -40℃ to +85℃ (medium/ambient temperature).

4. **Low noise & reliability**: ≤60dB noise levels for quiet operation, with SUS 304 stainless steel fasteners and PPA GF motor windings for corrosion resistance.
