3-inch DC Solar Centrifugal Pump ARL-4SPN8-2P

3-inch DC Solar Centrifugal Pump ARL-4SPN8-2P

The 3-inch DC Solar Centrifugal Pump ARL-4SPN8-2P is a highly efficient 600W DC solar centrifugal pump system, engineered for a variety of water pumping applications. Constructed from durable AISI 304 stainless steel and featuring an encapsulated water-filled BLDC motor, this pump ensures long-lasting performance and environmental safety. With an internal MPPT controller, the system intelligently optimizes solar power input, allowing it to deliver a maximum head of 21 meters and a robust flow rate of 15.1 cubic meters per hour. The pump is designed for easy installation and includes comprehensive protection features to ensure reliable operation. While the controller is IP65 rated, it’s recommended to install it away from direct sunlight for optimal longevity.
