4" Unterwasserpumpen

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 pressurisation. 
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 150 gm/m3 . Installation is possible in the vertical and horizontal position.
