Compact Electric Coolant Pump for Chemical Heat Exchanger Systems - High-Flow

Engineered specifically for chemical industry heat exchange equipment, the OWP-BL800H-D3-2 Electric Coolant Pump delivers reliable medium circulation tailored to the cyclic operating conditions of conventional heat exchange systems. Its stainless steel wet parts and robust shielded design ensure resistance to cooling medium erosion, while optimized flow and power characteristics make it a dependable choice for maintaining efficient heat transfer in chemical processing environments.

1. Closed Impeller Design: The closed impeller optimizes hydraulic performance, achieving high operational efficiency while limiting noise output to ≤60dB. This design ensures consistent flow distribution, critical for maintaining uniform heat transfer efficiency in heat exchanger circuits where flow stability directly impacts thermal performance.
2. Permanent Magnet Brushless Technology: The integrated permanent magnet brushless motor enables a compact form factor and low power consumption, aligning with energy-saving requirements in industrial applications. This motor design enhances power conversion efficiency without compromising the 800W rated output needed for heat exchanger circulation.
3. Long-Life Shaft Assembly: The shaft system employs ultra-durable friction pair materials, selected to withstand prolonged cyclic operation in chemical media. This construction extends the pump’s service life beyond 40,000 hours, reducing maintenance frequency and ensuring uninterrupted performance in continuous-process heat exchange systems.
4. Centrifugal & Shielded Configuration: The combined centrifugal and shielded structure eliminates leakage risks while preserving high efficiency. The shielded design isolates internal components from corrosive media, ensuring leak-proof operation and protecting both the pump and heat exchanger system from contamination.
5. Dual Speed Control Capability: Standard RS485 communication supports precise speed adjustment, with an optional PWM control mode to adapt to varying heat exchanger loads. This flexibility allows real-time optimization of circulation rates, matching pump output to dynamic thermal demands in fluctuating process conditions.
6. Comprehensive Protection Features: Built-in safeguards against reverse polarity, overvoltage, overcurrent, dry running, and overtemperature prevent component damage during abnormal operations. These protections enhance system reliability and minimize downtime in critical chemical heat exchange applications.
7. Corrosion-Resistant Construction: Stainless steel wet parts provide robust resistance to damage from cooling media such as glycol-water mixtures, dielectric oil, and electronic fluorinated solutions. This material compatibility ensures the pump maintains structural integrity and performance in corrosive chemical processing environments.

The OWP-BL800H-D3-2 Electric Coolant Pump is specifically optimized for the cyclic operating conditions of conventional chemical heat exchange equipment. Its 800W rated power is precisely matched to the circulation demands of standard heat exchanger systems, delivering a rated flow rate of 125L/min (up to 200L/min maximum) and 30M lift head to ensure efficient medium circulation. The stainless steel wet parts resist erosion from corrosive cooling media, a key requirement in chemical processing where media compatibility prevents equipment degradation. With a medium temperature range of -40℃ to 80℃, the pump adapts to the thermal variations of heat exchanger operations, maintaining performance across extreme temperature conditions. The IP67 protection rating allows installation in harsh industrial environments, while the ≤60dB noise level supports workplace safety. Additionally, the pump’s long service life and comprehensive protection features reduce maintenance costs, making it a reliable, cost-effective solution for chemical manufacturers seeking consistent heat transfer efficiency in their heat exchange systems.
