Description :

The 6SDM25 6" High-lift Overload Protection Insulated Wire Borehole Submersible Pump is a powerful and reliable water pumping solution designed for high-lift applications in boreholes. This pump is equipped with overload protection and insulated wire features, ensuring safety and optimal performance.

Applications :

Provides water supply from wells or reservoirs for various use cases.

Caters to domestic, civil, and industrial applications with stable performance.

Supports garden maintenance and agricultural irrigation operations efficiently.

Key Features :

1、Overload Protection : The overload protection feature of the pump is designed to prevent motor burnout and damage caused by excessive load or electrical issues. It automatically shuts off the pump when an overload is detected, ensuring the longevity and reliability of the pump.
2、The insulated wire feature adds an extra layer of safety to the pump. It helps to prevent electrical issues and ensures that the pump operates smoothly and efficiently.
3、The 6SDM25 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.
4、The high-lift capability of the 6SDM25 pump allows it to efficiently lift water from deep wells or boreholes to higher elevations. This makes it suitable for applications where water needs to be transported over long distances or to elevated locations
