3SR

3" submersible pumps

Description
˜3" submersible pumps suitable for pumping clean water for many applications such as domestic supply, irrigation and water systems for small communities.
The hydraulic components, coupled to a high performance electric motor, make the 3SR pump extremely efficient in 3" category.
Economic savings on the use of water thanks to the high efficiency and the consequent reduced electricity consumption. With a diameter of only 3 inches, the costs of drilling a new well and the installation are greatly reduced.
In the case of pre-existing drilling the 3SR pump is the ideal replacement solution, especially in the presence of old and encrusted wells. The construction with floating impellers allows the pumping of water with sand content of up to 150 g/m3.
Installation is possible in vertical or horizontal position.
