Key Applications
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).
Core Advantages
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.
