Automotive Water Pump OWPD250LQ-24-P38 High Capacity and Quality for HEV Buses Battery Cooling

The OWPD250LQ-24-P38 Electric Water Pump is a high-performance, durable solution engineered for precise liquid circulation, ideal for demanding cooling and thermal management needs. Its core working principle relies on a single-stage centrifugal design paired with magnetic force transmission (shield pump structure), which eliminates leakage risks while ensuring efficient fluid transfer. Powered by a high-efficiency brushless DC (BLDC) motor, it uses PWM speed control to adjust flow dynamically, and integrates multi-layer protections—including reverse polarity, dry running, over-voltage, over-current, overload, and over-temperature safeguards—to ensure stable operation even in harsh conditions.

This versatile pump excels in thermal management across industries, including:

• Electric Vehicles (EVs): EV motor cooling, motor controller cooling, battery thermal management (BMS), and coolant circulation for EV charging stations.
• High-Tech Cooling: Large-scale GPU cooling, supercomputer cooling, immersion cooling for data centers, and communication base station cooling.
• Industrial & Energy: Fuel cell cooling, battery energy storage cooling, turbocharger intercooler circulation, glycol boosters, and electric insulating oil boosting.
• Automotive/Heavy-Duty: Electric truck coolant systems, automotive antifreeze circulation, and liquid-cooled supercharger pumps.

1. Superior Efficiency: Professional electromagnetic design boosts motor efficiency by 3-5% vs. competitors; hydraulic simulation optimizes impeller-volute matching for higher fluid transfer efficiency.
2. Extreme Durability: IP67 waterproofing, SUS 304 stainless steel fasteners, and automotive-grade electronic components enable operation in -40℃ to +85℃ temperatures and humidity ≤90%.
3. Low Maintenance: BLDC motor delivers over 20,000 hours of service life, while magnetic transmission and dry-running protection reduce wear and failure risks.

Primary markets include EV manufacturers, data center infrastructure providers, renewable energy (battery storage/fuel cell) companies, industrial cooling system integrators, and high-performance computing (HPC) suppliers seeking reliable, energy-efficient liquid circulation solutions.
