Whether cooling complex mold cavities or regulating temperature in continuous production cycles, this pump meets the rigorous standards of modern injection molding processes.

• High-Efficiency Closed Impeller Design: The enclosed impeller structure optimizes fluid dynamics, minimizing energy loss and enhancing pump efficiency. This design also contributes to low noise operation (≤60dB), creating a quieter working environment for precision manufacturing facilities.
• Permanent Magnet Brushless Technology: The brushless motor configuration reduces power consumption while achieving a compact footprint, making the pump easy to install in space-constrained injection molding setups. Its efficient power conversion ensures consistent performance without compromising on flow rate or lift capacity.
• Long-Life Shaft Assembly: Equipped with ultra-durable friction pair materials in the shaft system, the pump exceeds 40,000 hours of service life, reducing maintenance frequency and operational downtime for injection molding operations.
• Leak-Proof Centrifugal & Shielded Structure: The combination of centrifugal pumping principle and shielded design eliminates leakage risks, protecting both the pump and surrounding equipment from fluid contamination. This feature is critical for handling corrosive media like glycol-water mixtures and electronic fluorinated solutions.
• Dual Speed Regulation Options: With standard RS485 communication and optional PWM control, the pump allows precise flow rate adjustment to match dynamic cooling demands in injection molding. This flexibility ensures optimal temperature control for different mold designs and production parameters.
• Comprehensive Protection Mechanisms: Integrated safeguards against reverse connection, overvoltage, overcurrent, dry running, and overtemperature prevent pump damage and extend service life. These protective features enhance operational safety and reduce the risk of production interruptions.
• Corrosion-Resistant Wet Parts: Stainless steel construction for wetted components ensures compatibility with a wide range of cooling media, including corrosive glycol mixtures and dielectric oils, making the pump suitable for long-term use in aggressive industrial environments.
