Сообщение 2025-11-11 08:23:46

As farms, households, and industries search for sustainable solar water pumping solutions, solar-powered systems are emerging as the top choice. The SAMKING 4SPN3-18-A solar pump combines advanced technology with renewable energy to serve multiple applications—ranging from supplying fresh water to livestock to powering a solar thermal pump station for heating and circulation.

This blog explores why the 4SPN3-18-A solar water pump is an ideal choice for a water trough and how it works as a solar thermal circulation pump in different systems.

Introducing the 4SPN3-18-A Solar Thermal Pump

Manufactured by SAMKING, the 4SPN3-18-A is a robust 3000 W (≈4.02 HP) solar submersible pump that operates in both AC and DC modes. Housed in stainless steel (AISI-304) and driven by a high-efficiency PMSM (brushless DC motor), it’s built for durability and seamless integration into solar-equipped systems

Key specifications include:

Max Head: 191 m
Max Flow: 7.0 m³/h
Outlet Size: 1.25″
Internal MPPT Controller (up to 98% MPPT efficiency)
Voltage Compatibility: DC (60–450 V) and AC (150–240 V)
Motor Submersion Ratings: Up to 150 m depth, water temp up to 40 °C
Insulation & Protection: Class F, IPX8 (motor), IP65 (controller)
Certifications: CE, TUV, SUD, UL, ISO 9001 & ISO 14001

Why Choose a Solar Water Pump for Water Troughs?

Livestock health depends on a continuous supply of clean water. A solar water pump for water troughs ensures:

Uninterrupted water supply in remote, off-grid areas.
Energy savings by running directly on solar water pump panels without high electricity bills.
Durability and low maintenance, with stainless steel design and built-in protections like dry-run and overload safeguards.
Flexibility, as the SAMKING 4SPN3-18-A runs on both DC solar power and AC backup power when needed.

With its 7.0 m³/h flow rate and 191 m maximum head, this pump can draw water from deep wells and reliably deliver it to troughs across long distances.

Understanding the Solar Thermal Pump

A solar thermal pump is engineered to circulate hot water or fluids in solar heating systems. Unlike traditional pumps that depend on grid electricity, the SAMKING solar thermal pump runs efficiently on solar energy, ensuring uninterrupted circulation.

Key Advantages:

Energy independence – Operates directly from solar panels.
High durability – Stainless steel build for harsh environments.
Hybrid flexibility – Switches between DC solar input and AC grid power or generator backup.

The Role of a Solar Thermal Water Pump

The solar thermal water pump is ideal for homes, businesses, and farms seeking to reduce reliance on fossil fuels. Applications include:

Domestic hot water circulation – moving heated water from solar collectors to storage tanks.
Pool and spa heating – maintaining warm water efficiently.
Greenhouse heating – circulating warm water to maintain optimal plant growth conditions.

By incorporating this pump, users can achieve significant energy savings, while reducing their carbon footprint.

Conclusion

Whether you need a solar water pump for water troughs on your farm, a solar thermal pump station for large-scale irrigation, or a solar thermal circulation pump for domestic heating systems, the SAMKING 4SPN3-18-A delivers unmatched versatility and performance.

It’s not just a pump—it’s a sustainable investment for agriculture, households, and industries looking to cut costs and embrace renewable energy.
