The OWP-BL43-300 Electric Coolant Pump is a high-performance, industry-grade fluid circulation system specifically developed to address the stringent liquid cooling requirements of reflow ovens. Leveraging advanced brushless DC motor technology and a shielded pump configuration, this pump delivers consistent flow regulation, comprehensive protection features, and durable operation—making it an indispensable component for maintaining precise temperature control and production reliability in reflow soldering processes.

Engineered for harsh reflow oven environments, this electric coolant pump integrates a suite of intelligent functions to ensure stable and safe operation. It features constant flow control to maintain uniform cooling performance, eliminating temperature fluctuations that could compromise solder joint quality. The pump is equipped with full-spectrum protection capabilities, including reverse polarity protection, dry running protection, over-voltage/over-current protection, and overload/over-temperature protection—effectively shielding both the pump and reflow oven components from potential damage. Its magnetic force transmission (shielded pump structure) eliminates leakage risks, while the high-efficiency brushless DC motor design ensures minimal power consumption and an extended service life of over 20000 hours.

The OWP-BL43-300 is meticulously designed to optimize the liquid cooling systems of reflow ovens, addressing critical heat management challenges in soldering processes. In high-precision reflow applications (such as Mini LED packaging, semiconductor component soldering, and automotive electronics assembly), the pump enables efficient coolant circulation in cooling zones, rapidly dissipating excess heat from heated PCBs and oven chambers. By maintaining stable coolant flow and precise temperature control (facilitated by PWM speed regulation), it ensures consistent cooling rates (0.5-3℃/s) that are essential for forming reliable solder joints and preventing thermal deformation of sensitive electronic components. Its IP68 waterproof and dustproof rating makes it resistant to flux fumes and workshop contaminants, while the wide operating temperature range (-40℃ to +85℃) adapts to extreme production environments. Whether for 24/7 continuous operation in high-volume SMT lines or precision soldering in specialty manufacturing, this pump delivers the reliable cooling performance needed to enhance process stability and product yield.
