High Efficiency Electric Water Pump for Blockchain Servers Cooling System with Long Service Life
OWP-BL93-300 Brushless DC Centrifugal Pump: Working Principle, Uses, Advantages & Specs
The OWP-BL93-300 is a high-performance single-stage centrifugal pump designed for efficient fluid transfer in demanding cooling applications. Its core working principle relies on magnetic force transmission (shielded pump structure) and a brushless DC motor: the motor drives an impeller to rotate at constant speed, creating centrifugal force that draws in fluids (e.g., glycol-water mixtures, dielectric oil) and pushes them through the volute—optimized via professional hydraulic simulation software for maximum flow efficiency. The brushless motor, paired with automotive-grade electronics, ensures low power consumption while delivering consistent performance, with built-in protections (dry running, reverse polarity, over-voltage/current/temperature) to prevent damage in harsh conditions.
Key Uses
This pump excels in thermal management across industries:
- EV & Automotive: Cooling EV motors, motor controllers, batteries, and turbocharger intercoolers; thermal management for electrified engineering vehicles.
- Data & Computing: Large-scale GPU cooling, supercomputer cooling, and IT fluid cooling solutions (ideal for immersion cooling systems).
- Energy & Industrial: Battery energy storage cooling, fuel cell cooling, communication base station cooling, and industrial cooling systems.
Core Advantages
- Higher Efficiency: Professional electromagnetic design boosts motor efficiency by 3-5% vs. competitors; optimized impeller-volute matching enhances hydraulic efficiency.
- Extreme Durability: IP68 waterproof rating (per IEC 60529) and -40℃ to +85℃ operating temperature range (medium/ambient) suit harsh environments; >20,000-hour service life at rated voltage (12V) and 36℃ ambient.
- Reliable Protection: Integrates dry running, reverse polarity, over-voltage, over-current, overload, and over-temperature protections to minimize downtime.
- Lightweight & Robust: Weighs only 1.1kg with a die-cast aluminum housing (sandblasted/impregnated) and SUS 304 stainless steel hardware for corrosion resistance.
