In remote agricultural environments, rural households, or off-grid installations, access to a consistent and efficient water supply is non-negotiable. The SAMKING 3SPN1-11P 600W Brushless DC Solar Submersible Water Pump offers a dependable, energy-efficient solution designed to meet the modern demands of water delivery — without relying on grid power or fossil fuels.

Backed by SAMKING’s expertise in solar pumping systems, the 3SPN1-11P stands out as a compact yet powerful option for deep-well water extraction, with the versatility to support irrigation, livestock, and domestic supply.

Designed for Sustainable Water Delivery

The 3SPN1-11P is purpose-built for solar operation. With a 600W brushless DC motor, it runs directly on solar panel input, offering a clean and cost-effective solution for areas where grid access is limited or unavailable. Its design eliminates the need for inverters, fuel, or batteries — although it can be integrated with a controller and batteries for extended operation if required.

Using solar energy reduces long-term operating costs and environmental impact while increasing energy independence for rural users.

How SAMKING Submersible Water Pumps Work Using Solar Power

Key Technical Specifications

• Model – 3SPN1-11P
• Rated – Power 600W
• Rated Voltage – DC 60V–72V
• Maximum Head – 114 meters
• Maximum Flow Rate – 1.0 m³/h (approximately 16.6 L/min)
• Outlet Size – 1 inch
• Motor Type – Brushless DC
• Minimum Well Diameter– 3 inches
• Compatible Solar Panel – 900W (Recommended)

These specifications make the pump suitable for deep wells, boreholes, and other demanding environments, with a stable output ideal for small to mid-scale water needs.

Brushless DC Motor Advantage

Unlike conventional AC solar pumps, the brushless DC motor in the 3SPN1-11P offers high efficiency, longer service life, and low maintenance. The absence of brushes means less mechanical wear and better thermal performance — all of which are critical in harsh field conditions.

Moreover, it allows for soft-start functionality, improving system safety and reducing stress on both the pump and power source.

Built to Withstand Harsh Environments

Durability is a key factor in solar pumping systems deployed in remote or semi-permanent installations. The 3SPN1-11P features corrosion-resistant stainless steel construction for both the pump body and impeller components. This ensures long-term reliability even in high-mineral-content water sources.

The water-lubricated bearing system also reduces operational noise and mechanical friction, further extending the pump’s life.

Wide Range of Applications

Thanks to its high head and efficient flow rate, this model suits multiple applications:

• Agricultural irrigation: Efficiently supplies water to small fields, greenhouses, or drip irrigation systems.
• Livestock and poultry farming: Delivers consistent water to troughs and tanks without the need for daily manual refilling.
• Off-grid domestic water supply: Provides clean water to remote homes, cabins, or homesteads where grid electricity is not an option.
• Rainwater harvesting and tank refilling: Complements water conservation systems for sustainable water use.

Its compact diameter makes it ideal for wells as narrow as 3 inches, broadening its usability across different property types.
