3-inch DC Solar Centrifugal Pump ARL-4SPW2-11

3-inch DC Solar Centrifugal Pump ARL-4SPW2-11

The 3-inch DC Solar Centrifugal Pump ARL-4SPW2-11 is a highly efficient 3-inch DC solar centrifugal pump, designed for a variety of water pumping applications. It features an 1800W / 2.41HP BLDC motor and an external MPPT controller, allowing it to reach a maximum head of 116 meters and a flow rate of 6.1 cubic meters per hour. Constructed with a stainless steel 304 pump body and impeller, the ARL-4SPW2-11 utilizes an encapsulated water-filled motor to prevent pollution and ensure a longer operational life. Its soft-start running capability and thrust bearing system further enhance its durability and performance. This pump is powered by DC only, making it ideal for solar applications.
