| Clean water
---|---
| Domestic use
| Civil use
PERFORMANCE RANGE
- Flow rate up to 120 l/min ( 7. 2 m 3/h)
- Head up to 267 m
INSTALLATION AND USE
3-inch submersible pumps are designed to transfer clean water, making them perfect for household use, irrigation, and small community water systems.
KEY FEATURES
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.
