The 3SR 5/8 is recommended for domestic and civil use, in particular it can be used for domestic supply, irrigation and small water systems.

The pump can move clean water with sand content up to 150 grams per cubic meter. The motor of this pump is made with rewindable oil bath operation.

It has a flow rate that varies from 15 to 120 litres per minute with a head of 8 to 24 metres.

The 3SR 5/8 is a small pump and is therefore easy to install in wells. It can be mounted up to 100 meters deep with a suitable power cable. The water and dust protection classification of the pump is IP68.

It must be powered by a three-phase voltage, has a horsepower of 0.5 HP and the temperature of the liquid to be pumped reaches up to +35 degrees centigrade.

The 3SR 5/8 benefits from a solid construction, it is made of AISI 304 stainless steel which makes it robust and resistant.
