The OWP-BL400H-D2-21 stainless steel brushless electric water pump is a high-performance cooling component engineered for demanding applications in off-grid power generation and energy storage thermal management systems. This robust pump also serves critical roles in data center server liquid cooling, AI computing center cooling equipment, marine engine and battery cooling, copper-containing component liquid cooling, and electric vehicle charging/swapping station thermal management.

• Durability & Longevity: Stainless steel water-contacting components and IP68 protection rating provide exceptional corrosion resistance and protection against dust/water intrusion, with a working life exceeding 20,000 hours.
• Stable Performance: Operates at DC18V-32V (rated DC24V) with 400W±5% rated power, delivering ≥20m head at 3000L/h flow; PWM speed control enables flexible cooling adjustment.
• Comprehensive Protection: Features reverse connection, no-load, locked-rotor, over-voltage, and under-voltage protection to prevent damage; high/low level signal feedback allows real-time status monitoring.
• Low Noise & Air Tightness: Generates ≤60dB(A) noise at 1m (loaded) for quiet operation; air tightness test at 0.35Mpa shows leakage <0.8mL/min for reliable performance.
• Wide Adaptability: Functions in -40℃~85℃ working environment (relative humidity ≤90%) and handles -40℃~85℃ coolant; flange quick-connect design simplifies installation.
