4SR-F Submersible Pump

Description
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 200 gm/m3 . Installation is possible in the
vertical and horizontal position.
