3SPN2-11
The 3SPN2-11 DC solar submersible water pump is a high-performance centrifugal pump designed for efficient irrigation applications, featuring a 1.25-inch outlet and a powerful 1200W (1.61 HP) motor. It delivers a maximum head of up to 75 meters and a maximum flow rate of 5.0 cubic meters per hour, making it suitable for deep-well and agricultural water supply needs. The pump is equipped with an internal controller for automatic operation and uses a water-filled permanent magnet synchronous motor (PMSM) to ensure reliable performance, high efficiency, and long service life. Built specifically for solar power systems, this automatic solar submersible pump provides a dependable and energy-efficient solution for irrigation and water transfer in off-grid locations.
The solar water pump motor has a power rating of 1200W 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 performance and long service life. The motor operates at a maximum DC current of 15A and is designed for submersion depths of up to 150 meters, with a maximum allowable water temperature of 40°C. It delivers an efficiency of up to 85% and is built with insulation class F for enhanced thermal resistance. The maximum DC open-circuit voltage is 100V, while the optimal operating voltage range is between 40V and 90V. Depending on the impeller type, the maximum speed reaches 4500 RPM with plastic components, and 4000 RPM with SS304 or helical configurations. The motor is rated IPX8 for full submersible protection and requires a minimum cooling flow of 0.5 liters per second to maintain optimal operation.
