The Electric Coolant Pump OWP-BL43-426C is a high-performance solution designed to meet the demanding heat dissipation needs of industrial equipment, with a primary focus on reflow oven liquid cooling applications. Its robust design, precise control, and wide compatibility make it a reliable choice for enhancing thermal management efficiency in electronic manufacturing processes.

The pump is primarily engineered for industrial thermal management, with its most critical use case centered on reflow oven liquid cooling systems (the core application for electronic manufacturing):

• Ensures precise post-soldering cooling: Reflow ovens require rapid, uniform cooling after the heating phase to avoid solder defects (e.g., tombstoning, cold joints) and protect sensitive PCB components. The pump circulates cooling mediums (glycol-water mixtures, dielectric oil, etc.) to absorb heat efficiently, maintaining stable thermal conditions during soldering.
• Adapts to industrial reflow oven demands: Its high rated flow rate (2400L/H @ H=17M, max 5000L/H) and 20M max lift head support reliable fluid circulation even in large, high-power reflow ovens, covering the thermal needs of both standard PCBs and dense semiconductor packages.
• Withstands harsh oven environments: Operates seamlessly in reflow oven workspaces—thanks to a wide ambient temperature range (-40℃ to +85℃) and IP68 dust/liquid protection—ensuring durability in manufacturing settings where temperature fluctuations and debris are common.
• Enables recipe-based cooling control: PWM speed regulation lets operators adjust flow rates to match specific reflow soldering recipes, optimizing cooling for different PCB densities or component types (e.g., high-power vs. low-power PCBs).

• Superior protective features:
  • Prevents operational failures: Equipped with reverse polarity protection, dry running protection, and safeguards against over-voltage, over-current, overload, and over-temperature—minimizing downtime and extending the pump’s service life.
  • Maintains stable performance: Built-in constant flow control ensures consistent cooling medium circulation, avoiding temperature inconsistencies that could harm reflow soldering quality.
• Reliable & long-lasting design:
  • Leak-free operation: Uses magnetic force transmission (shield pump structure) to eliminate fluid leakage risks, critical for handling cooling mediums in precision manufacturing.
  • High-efficiency, durable motor: A brushless DC motor reduces power consumption while delivering a service life of over 20,000 hours, lowering long-term maintenance and replacement costs.
• User-friendly & versatile:
  • Easy installation/maintenance: Flange quick-connect design simplifies setup and disassembly, saving time for factory technicians.
  • Low operational noise: Operates at ≤60dB, improving workplace comfort in manufacturing facilities.

Wide medium compatibility: Works with glycol-water (50-60%), dielectric oil, mineral oil, and electronic fluorinated solutions, adapting to diverse reflow oven cooling system requirements.
