# OWPD250L-24-P38 BLDC Electric Water Pump: Reliable Cooling for EVs, Industrial & Data Center Applications

The OWPD250L-24-P38 is a high-performance brushless DC (BLDC) electric water pump engineered for demanding cooling systems, leveraging magnetic force transmission (shield pump structure) and single-stage centrifugal design. Its working principle combines professional electromagnetic theory with optimized hydraulic simulation: the BLDC motor—encapsulated with nylon plastic magnets and SUS 304 stainless steel fasteners—drives the impeller to deliver consistent flow, while PWM speed control ensures precise adjustment. Equipped with comprehensive protections (reverse polarity, dry running, over-voltage/current/load/temperature), it operates safely in extreme conditions, backed by an IP67 waterproof rating and >20,000-hour service life.

This versatile pump excels across key applications: EV motor/controller cooling, battery thermal management (BMS), high-power EV charging station cooling, and fuel cell cooling. It also serves industrial needs like turbocharger intercooling, battery energy storage systems, immersion cooling for data centers/supercomputers, GPU cooling, communication base station cooling, and glycol/fluorinated liquid circulation. Automotive-grade electronic components and a wide operating temperature range (-40℃ to +85℃) make it ideal for harsh environments, from electric trucks to industrial cooling systems.

Key advantages set it apart from competitors: 3-5% higher motor efficiency via validated electromagnetic design, superior hydraulic performance from software-optimized impeller-volute matching, and ruggedness from automotive-grade parts. With a rated power of 250W, it delivers 2800L/H at 16M lift (max flow 4800L/H, max lift 20M) with ≤60dB noise, ensuring efficient, quiet operation.
