The 48V 400mm Centrifugal Fan for Water Pumps represents a specialized cooling solution engineered specifically for water pump systems. Combining compact design with high-performance airflow, this centrifugal fan delivers reliable thermal management for various pump applications. Operating on a safe 48V low-voltage power supply, it eliminates the risks associated with higher voltage systems while maintaining optimal performance. The 400mm impeller diameter ensures sufficient air movement to prevent overheating in continuous operation scenarios, making it an essential component for maintaining water pump efficiency and extending service life.
Equipped with a high-efficiency motor, this centrifugal fan achieves an impressive static pressure range of 500-5,330 Pa, ensuring effective heat dissipation even in confined pump enclosures. The optimized impeller design minimizes air resistance, resulting in airflow rates up to 15,000 m³/h while maintaining energy consumption at economical levels.
Constructed with corrosion-resistant materials including stainless steel components and anti-rust coatings, the fan is specifically designed to withstand the humid environments typical of water pump installations. The robust housing protects internal components from moisture and particulate matter, ensuring reliable operation in challenging conditions.
Featuring thermal overload protection and insulated wiring, the 48V 400mm Centrifugal Fan meets international safety standards for electrical equipment. The low-voltage operation reduces electrical hazards, making it suitable for both indoor and outdoor installations. The fan's sealed motor design prevents water ingress, achieving an IP54 protection rating for enhanced durability.
Ideal for cooling large industrial water pumps used in manufacturing facilities, this fan maintains optimal operating temperatures during continuous duty cycles. Its high airflow capacity effectively dissipates heat generated by heavy-duty pump motors.
In agricultural settings, the fan provides essential cooling for irrigation pump stations, ensuring reliable water delivery for crops even in high-temperature environments. Its corrosion-resistant properties make it suitable for farm conditions.
Within water treatment plants, the fan contributes to the cooling of circulation pumps and filtration system motors. Its ability to operate in humid environments ensures consistent performance in these critical applications.
The 48V 400mm Centrifugal Fan operates at a noise level of 65-75 dB(A), well within the industrial noise standards specified by ISO 3744 and GB/T 2888, which recommend noise levels below 85 dB(A) for industrial environments.
Under normal operating conditions and with proper maintenance, the fan motor is designed to provide a service life of approximately 20,000 hours of operation. Regular cleaning of the impeller and housing extends this lifespan further.
While specifically optimized for medium to large water pumps, the fan's versatile mounting options allow for adaptation to various pump models. The 400mm size provides sufficient airflow for most industrial pump configurations.
While the fan comes with mounting hardware and installation instructions, professional electrical installation is recommended to ensure proper wiring and alignment with the pump system. This ensures optimal performance and safety compliance.
