4SR 10/5 N-PS - 1 HP three-phase submersible electric pump
Flow rate up to 250 l/min (15 m³/h). Head up to 31.5 metres. 0.75 kW (1 HP) motor.




The 4SR 10/5 N-PS submersible electric pump from the 4SR series by Pedrollo , thanks to its refined design, offers exceptional performance and efficiency.
Recommended for agricultural, civil and domestic installations.
Its high efficiency and reliability make it suitable for water distribution in conjunction with pressure tanks, for irrigation, for washing systems and for pressure boosting.
The 4SR 10/5 N-PS, thanks also to its resistance to wear and corrosion, is among the best in the 4-inch submersible pump category.
It can pump clean water with a maximum sand content of 150 grams per cubic meter.
