Description

The 4SR 12/18 N-PS submersible electric pump from the 4SR series by Pedrollo can pump clean water and chemically non-aggressive liquids for the components.

The hydraulic design ensures exceptional performance and efficiency combined with greater resistance than that found in other series.

It allows for considerable energy savings which also translates into water savings.

The 4SR 12/18 N-PS can be installed both horizontally and vertically up to 300 metres below water level.

Pedrollo has created a solid and robust product, thanks to the use of stainless steel, built to last over time.
