3SRm 2/21 - 0.75 HP single-phase submersible electric pump
Flow rate up to 50 l/min (2.7 m³/h). Head up to 84 meters. 0.55 kW (0.75 HP) motor.




The 3SRm 2/21 submersible electric pump from the 3SR series by Pedrollo is recommended for domestic and civil installations.
It can pump clean water with sand content up to 150 grams per cubic meter.
Collation can be carried out, using a special cable, up to 100 metres below the water level, exclusively vertically.
Compact and lightweight, the 3SRm 2/21 can be easily installed in wells 3 inches or larger.
The use of stainless steel makes the electric pump extremely solid and resistant.
