Description :

The 3.5SDM2 Borehole Submersible Pump is a reliable and efficient water pumping solution designed for borehole applications. It allows for efficient water flow and reduces energy consumption, ensuring optimal water extraction from boreholes.. Its durable construction, submersible design, and user-friendly operation make it a dependable choice for extracting water from boreholes.

Key Features :

1、This pump features a double rings hole design and a stainless steel thickened base, ensuring durability and long-lasting performance.The double rings hole design enhances the pump's efficiency and performance.
2、The stainless steel thickened base adds to the pump's durability and resistance to corrosion. This ensures that the pump can withstand the harsh conditions of being submerged in water for extended periods, providing reliable performance over time.
3、The submersible design of the pump allows it to be fully submerged in water, maximizing efficiency and minimizing noise. It eliminates the need for priming, making the pump easy to operate and maintain.
4、 Maximum fluid temperature up to +35℃
Maximum sand content : 0.25%
Minimum well diameter : 3.5"
