4SRm 6/4 S-PS - 0.75 HP single-phase submersible electric pump
Flow rate up to 150 l/min (9 m³/h). Head up to 26.5 meters. 0.55 kW (0.75 HP) motor.




The 4SRm 6/4 S-PS submersible electric pump from the 4SR series by Pedrollo can pump clean water with a maximum sand content of 200 grams per cubic meter.
The refined hydraulic design ensures remarkable resistance to wear caused by the presence of water in the sand.
The construction is solid and robust, made to last over time.
The 4SRm 6/4 S-PS is suitable for water distribution in conjunction with pressure tanks, for irrigation, for washing systems and for pressure boosting.
It can be installed both vertically and horizontally up to 300 meters below water level.
