Description
The 3SRm 1/31 submersible electric pump from the 3SR series by Pedrollo guarantees high performance with consequent economic savings.
The hydraulic components, coupled with a high-efficiency electric motor, make the electric pump extremely efficient in the 3-inch category.
Its construction allows it to pump water with a sand content of up to 50 grams per cubic meter.
The 3SRm 1/31 can only be installed vertically up to 100 meters below water level.
Pedrollo created the electric pump with a mix of AISI 304 and 316L stainless steel to provide resistance and solidity.
