The Evergreen V4 Borewell Submersible Pump is another type of submersible pump commonly used for borehole applications. It's designed to be submerged in the water, typically deep within a borewell, to pump water to the surface. The "V4" designation usually refers to the pump's diameter, with V4 pumps having a 4-inch diameter, which is a common size for borewell pumps.
These pumps are often used in agricultural, industrial, and domestic settings where there's a need to draw water from underground sources. They come in various power ratings and configurations to suit different borehole depths and water pumping requirements. The "Evergreen" brand likely signifies reliability and longevity, traits important for equipment operating in harsh conditions like submersible pumps in borewells.
