High-Efficiency Electric Coolant Pump for Injection Mold Cooling Circuits - Corrosion-Resistant Shielded Design

Designed for demanding thermal management in injection mold cooling systems, the OWP-BL800H-D3-2 Electric Coolant Pump integrates advanced shielded technology and high-performance engineering to deliver reliable, long-lasting cooling solutions. This pump is optimized to handle corrosive media and extreme temperature ranges, making it an ideal choice for maintaining precise temperature control in industrial mold cooling circuits where efficiency and durability are critical.

• Closed Impeller Design: The adoption of a closed impeller ensures superior hydraulic efficiency, minimizing energy loss while reducing operational noise to ≤60dB. This design optimizes fluid dynamics, enabling consistent flow rates even under varying system pressures, which is essential for stable mold temperature control.
• Permanent Magnet Brushless Technology: Equipped with a permanent magnet brushless motor, the pump achieves compact dimensions and low power consumption without compromising performance. This motor technology enhances energy efficiency, directly contributing to reduced operational costs and environmental sustainability.
• Long-Life Shaft Assembly: The shaft system utilizes ultra-durable friction pair materials, specifically selected to withstand continuous operation under harsh conditions. This design extends the pump’s service life beyond 40,000 hours, reducing maintenance frequency and downtime for industrial applications.
• Centrifugal & Shielded Construction: The integrated centrifugal and shielded structure eliminates leakage risks while maintaining high operational efficiency. The shielded design prevents media contamination and protects internal components, ensuring reliable performance in corrosive medium environments.
• Dual Speed Regulation Options: Standard RS485 communication enables precise speed adjustment, with an optional PWM control mode to accommodate diverse system integration requirements. This flexibility allows for seamless integration into automated production lines, supporting real-time flow rate optimization.
• Comprehensive Protection Mechanisms: Built-in safeguards against reverse polarity, overvoltage, overcurrent, dry running, and overtemperature ensure the pump operates safely under abnormal conditions. These protections prevent component damage and extend service life, enhancing system reliability.
• Corrosion-Resistant Materials: Wet parts constructed from stainless steel provide exceptional resistance to corrosive media such as glycol-water mixtures and electronic fluorinated solutions. This material selection ensures compatibility with harsh cooling fluids, maintaining performance integrity over long-term use.

The OWP-BL800H-D3-2 Electric Coolant Pump is specifically engineered to meet the unique demands of injection mold cooling circuits. Its 800W rated power is precisely matched to the resistance characteristics of typical mold cooling loops, ensuring sufficient flow and pressure to maintain consistent temperatures across mold cavities. The stainless steel wet parts effectively resist moisture and corrosive media erosion, a common challenge in mold cooling systems where glycol-water mixtures are widely used. With a maximum flow rate of 200L/min and lift head of 30M, the pump efficiently circulates cooling media to dissipate heat generated during the injection molding process, preventing mold overheating and ensuring product quality stability. The IP67 protection rating allows for installation in harsh industrial environments, while the low noise operation (≤60dB) contributes to a safer and more comfortable workplace. Additionally, the pump’s long service life (＞40,000 hours) and comprehensive protection features minimize maintenance needs, making it a cost-effective and reliable solution for high-volume injection molding operations seeking consistent thermal management performance.
