Suitable for use in domestic, civil and industrial applications where the water, such as groundwater, surface water and sewage water, contains suspended solids up to Ø 50 mm.
4″ Submersible pumps suitable for pumping clean water for many applications such as domestic supply, irrigation for greenhouses, farms and water systems for communities and
The hydraulic components, coupled to a high performance electric motor, make the 4SR
pump extremely efficient in 4″ category.
Economic savings on the use of water thanks to the high efficiency and the consequent
reduced electricity consumption. The construction with floating impellers allows the
pumping of water with a sand content of up to 200 gm/m3 . Installation is possible in the
vertical and horizontal position.
