4SPN5-15
This is a 4SPN5-15 DC solar submersible water pump with a 1.5-inch outlet, designed with a centrifugal pumping system for efficient and reliable water delivery. It is powered by a high-performance 3000W (4.02HP) motor, capable of achieving a maximum head of 170 meters and a maximum flow rate of 9.7 cubic meters per hour. The pump features an internal controller and is equipped with a water-filled PMSM motor, which ensures stable operation, improved cooling, and long service life. Built specifically for demanding environments, this 1.5-inch solar submersible water well pump is ideal for rural irrigation applications, offering strong performance, energy efficiency, and dependable operation in off-grid water supply systems.
The solar water pump motor has a rated power of 3000W and is constructed from durable AISI 304 stainless steel, using a high-efficiency BLDC motor design. It features an encapsulated, water-filled structure with a thrust bearing system for reliable long-term operation. The motor operates on a maximum DC current of 15A and is suitable for submersion depths of up to 150 meters, handling water temperatures up to 40°C while achieving a maximum efficiency of 85%. It is built with insulation class F and supports a maximum open-circuit voltage (VOC) of 100V DC, with an optimal operating voltage range of 40–90V DC. Depending on the impeller type, the maximum speed is 4500 RPM for plastic, 4000 RPM for SS304, and 4000 RPM for helical configurations. The motor is fully waterproof with an IPX8 enclosure rating and requires a minimum cooling flow of 0.5 L/s to maintain optimal performance.
