Description :

The 4SPM2 4" Stainless Steel Impeller Overload Protection High Efficiency Borehole Submersible Pump is a reliable and efficient water pumping solution designed for borehole applications. This pump is equipped with a stainless steel impeller, overload protection, and high efficiency features.


Key Features :

1、The stainless steel impeller is a key feature of this pump, providing durability and resistance to corrosion. It is designed to efficiently move water, ensuring optimal performance and longevity of the pump.
2、The overload protection feature is designed to safeguard the pump from damage caused by excessive load or electrical issues. It automatically shuts off the pump when it detects an overload, preventing motor burnout and extending the lifespan of the pump.
3、The high efficiency design of the pump ensures that it operates with minimal energy consumption. This not only reduces electricity costs but also makes the pump environmentally friendly.
4、The 4SPM2 pump is specifically designed for borehole applications, allowing it to be fully submerged in water. This submersible design maximizes efficiency and minimizes noise, making it suitable for various settings including residential, commercial, or agricultural.
5、Maximum fluid temperature up to +50℃
6、Maximum sand content : 0.25%
7、Minimum well diameter : 4"
