3SRm 3" Submersible pumps & motors (Single Phase)
3SR 3" submersible borehole pumps are designed to transfer clean water, making them perfect for household use, irrigation, and small community water systems.
The increased efficiency of 3SR pumps not only saves electricity but also offers economic advantages. Their small size and light build allow for easy installation in wells 3 inches wide or more. With a blend of hydraulic parts and a high-efficiency motor, 3SR pumps excel in the 3-inch category, capable of handling water with up to 150 g/m3 of sand.
