Description
The 3SR 1/21 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 3SR 1/21 can be easily installed in 3-inch or larger wells.
The use of stainless steel makes the electric pump extremely solid and resistant.
