Description

The 4HR 18/4 - PS submersible electric pump from the 4HR series by Pedrollo is characterised by high mechanical resistance.

Its resistance to sand and corrosion makes it ideal for installations in coastal areas and in the presence of brackish water.

It can pump clean water with sand content not exceeding 100 grams per cubic meter of sand.

Made entirely of micro-cast stainless steel of considerable thickness, the 4HR 18/4 - PS is recommended when a high-quality product that guarantees a long operating life is required.

It can be installed up to 200 meters below water level both horizontally and vertically.
