Low-Noise Electric Coolant Pump for New Energy Lithium Battery Coaters - Ion

Custom-engineered for thermal management in new energy lithium battery coater equipment, the OWP-BL800H-D3-2 Electric Coolant Pump integrates ion-free stainless steel construction and high-performance circulation capabilities to meet the stringent requirements of lithium battery manufacturing. Its design prioritizes media purity and equipment protection, making it an ideal solution for coater cooling systems where corrosion prevention and stable flow are critical to production quality.

1. Closed Impeller Engineering: The closed impeller design optimizes hydraulic efficiency, enabling the pump to deliver consistent flow rates with minimal energy loss while restricting noise emissions to ≤60dB. This configuration ensures smooth fluid movement, which is essential for maintaining uniform temperature distribution across coater components, directly supporting coating precision.
2. Permanent Magnet Brushless Motor: Equipped with a permanent magnet brushless motor, the pump achieves a compact footprint and low power consumption without sacrificing its 800W rated output. This motor technology enhances energy efficiency, reducing operational costs and aligning with the sustainability goals of new energy manufacturing facilities.
3. Ultra-Durable Shaft System: The shaft assembly utilizes high-wear resistance friction pair materials, selected to withstand continuous operation in lithium battery production environments. This design extends the pump’s service life beyond 40,000 hours, minimizing maintenance downtime and ensuring reliable long-term performance in high-volume production lines.
4. Centrifugal & Shielded Structure: The integrated centrifugal and shielded design eliminates leakage risks while preserving high operational efficiency. The shielded construction prevents medium contamination and protects internal components, ensuring leak-proof operation even when handling corrosive fluids like glycol-water mixtures or dielectric oil.
5. Dual Speed Regulation Modes: Standard RS485 communication allows for precise speed adjustment, with an optional PWM control mode to adapt to dynamic coater cooling demands. This flexibility enables real-time flow optimization, matching pump output to varying production stages and ensuring consistent thermal management.
6. Multi-Layer Protection Mechanisms: Built-in safeguards against reverse polarity, overvoltage, overcurrent, dry running, and overtemperature prevent component damage under abnormal operating conditions. These protections enhance system reliability and mitigate the risk of production interruptions in critical lithium battery coating processes.
7. Ion-Free Corrosion Resistance: Wet parts constructed from stainless steel ensure no ion析出 (ion leaching), eliminating the risk of coater equipment corrosion. This material selection provides robust resistance to the pump’s compatible media, maintaining both pump integrity and the purity of cooling fluids in sensitive lithium battery manufacturing.

The OWP-BL800H-D3-2 Electric Coolant Pump is specifically tailored to the cooling requirements of new energy lithium battery coaters. Its 800W rated power is perfectly matched to the circulation demands of coater cooling systems, delivering a rated flow rate of 125L/min (up to 200L/min maximum) and 30M lift head to ensure efficient heat dissipation from coating rollers and other critical components. The stainless steel wet parts’ ion-free property eliminates the risk of equipment corrosion, a key concern in lithium battery production where even minor rust or contamination can compromise battery performance. With a medium temperature range of -40℃ to 80℃, the pump adapts to the thermal variations of coater operations, maintaining stable performance in both startup and continuous production phases. The IP67 protection rating allows installation in harsh industrial environments, while the ≤60dB noise level supports a safe workplace. Additionally, the pump’s long service life and comprehensive protection features reduce maintenance costs, making it a reliable, high-performance solution for lithium battery manufacturers seeking to optimize coater cooling and ensure consistent production quality.
