The electromagnetic clutch water pump developed by Risun for modern internal combustion engines adopts an electromagnetic clutch module, which can intelligently switch the pump's operational status based on engine conditions: it automatically disengages during cold starts to reduce warm-up time and instantly engages during high-temperature operation to guarantee cooling efficiency. This effectively reduces engine internal resistance and improves fuel economy. Furthermore, the electromagnetic clutch structure allows for dynamic switching of the drive system to change the fan rotation direction, serving the purpose of clearing flammable debris from the engine surface. Risun's electromagnetic clutch water pump innovatively combines the reliability of mechanical drive with the energy-saving advantages of intelligent control. Its precision-machined aluminum alloy pump body, paired with reinforced ceramic seals, offers both lightweight construction and superior durability. The optimized flow channel design ensures high-flow, low-pulsation circulation, making it particularly suitable for high-thermal-load engines like turbocharged units. The integrated circuit protection design provides resistance to interference and vibration, ensuring perfect compatibility with various electronic control systems.
