3SRm 5/6 - 0.33 HP single-phase submersible electric pump
Flow rate up to 120 l/min (7.2 m³/h). Head up to 18 m. 0.25 Kw (0.33 HP) motor.




The Pedrollo 3SRm 5/6 submersible electric pump is recommended for domestic and civil applications. It is primarily used for domestic water supply, irrigation, and water systems for small communities.
The hydraulic components, coupled with a high-efficiency electric motor, make this 3SR electric pump extremely efficient in the 3-inch category.
The 3SRm 5/6 allows you to save water thanks to its efficient performance and consequent reduced electricity consumption.
Its construction allows the pumping of water with a sand content of up to 150 grams per cubic meter.
Thanks to their compactness and lightness, this electric pump can be easily installed in wells of 3 inches or more.
The submersible motor is designed with a rewindable oil bath technique.
The 3SRm 5/6 can be installed up to 100 meters below water level, with an appropriately long power cable.
It has a flow rate that varies from 15 to 120 litres per minute with a head of 5 to 15 metres.
It must be powered by a single-phase voltage, has a horsepower of 0.33 HP and the temperature of the liquid to be pumped reaches up to +35 degrees centigrade.
The pump has an IP68 protection rating.
The 3SRm 5/6 has a pump body and shaft made of AISI 304 stainless steel and a noryl impeller which give the product good resistance and robustness.
