Advantages

  • Extreme Environment Adaptability
    IP68 top-level protection defends against dust and water immersion, paired with an ultra-wide temperature range (-50°C to +100°C) for stable operation in harsh climates—ideal for all vehicle working conditions.
  • Flexible & Reliable Power Compatibility
    Broad operating voltage (18–32VDC) matches 24VDC rated systems perfectly, resisting voltage fluctuations and ensuring steady performance even in complex automotive electrical environments.
  • High Efficiency & Low Noise Operation
    Delivers powerful flow (3000L/h) and head (13m) with only 240W rated power; load noise ≤60dB(A) achieves quiet running, meeting vehicle interior noise standards.
  • Long-Durability & Low Maintenance Cost
    ≥20000h long operating life reduces replacement frequency; lightweight design (2.2kg±5% with bracket) cuts installation labor and space costs.


Application

Ideal for new energy vehicle thermal management systems, Sunlight water pumps serve as a reliable core component for coolant circulation in both passenger and commercial EVs. Engineered to thrive in extreme climate zones—from frigid high-altitude areas to scorching desert regions—they deliver consistent performance in dust-laden, high-humidity, and vibration-intensive working conditions.
Beyond automotive applications, these pumps are also widely adopted in industrial cooling systems and heavy-duty equipment where stable, low-maintenance fluid circulation is critical. Their compact, easy-to-install design seamlessly integrates into OEM assembly lines and aftermarket upgrade projects, catering to the needs of global vehicle manufacturers, thermal system integrators, and maintenance service providers.

Installation Tips

1.Secure the pump firmly with the matched mounting bracket to avoid vibration-induced wear during long-term operation; compatible with both OEM assembly lines and aftermarket retrofitting projects.

2.Ensure tight sealing of fluid connections to prevent leaks; the pump’s robust structure allows flexible installation in confined engine bays or industrial equipment compartments.

3.Match the pump with compatible vehicle/equipment electrical systems for stable power supply; no additional voltage regulators required for mainstream setups.

4.Install the pump in a well-ventilated location to optimize heat dissipation and further extend service life.


Usage Tips

1.Use dedicated coolant media recommended for automotive thermal management systems to avoid clogging or corrosion of internal components.

2.Perform regular visual inspections of connections and surfaces; keep the pump free from dust and debris accumulation to maintain peak performance.

3.The pump operates reliably in extreme temperature zones—no extra protective measures needed for frigid high-altitude areas or scorching desert environments.

4.Shut down the pump promptly if abnormal noise or performance issues occur; contact our after-sales team for professional troubleshooting guidance.
