Speed Control
The OWP-BL43-450T Electric Coolant Pump is specifically tailored for heat dissipation in traction converters of metro and light rail systems, a critical application in the rail transit industry where thermal management directly impacts power conversion efficiency and operational safety. With a maximum flow rate of 9000L/H and 11M lift head, the pump efficiently circulates compatible cooling media to dissipate heat from IGBT modules, rectifiers, and inverters in traction converters—components that generate significant heat during power conversion for rail vehicle propulsion. Its wide medium temperature range (-40℃ to 85℃) adapts to extreme climates, from cold winters to hot summers, while the IP68 protection grade ensures resistance to dust, moisture, and harsh environmental factors in rail tunnels and outdoor routes. The PWM speed regulation and high/low-level fault feedback signal enable seamless integration with the rail vehicle’s control system, supporting real-time monitoring and adaptive cooling. This model’s compact design, low noise, and long service life make it an indispensable component for enhancing the reliability, safety, and efficiency of metro and light rail traction systems.
