Submersible pump Pedrollo 4SR2-39

For solving tasks requiring extremely high head and enormous volumes of water from deep wells, the Pedrollo 4SR2-39 hydraulic section is the optimal, unparalleled engineering solution. This advanced, patented design from the Italian manufacturer is specially developed for working with clean water containing up to 150 g/m³ of abrasive particles. Thanks to the unique combination of high-quality materials and an innovative front insert with axial impeller movement, this hydraulic section completely prevents sand ingress into the mechanism and prevents clogging, ensuring impeccable and highly efficient water supply in large industrial enterprises, large-scale agricultural complexes, and municipal systems.

Excellence in Every Detail: Patented Pedrollo Technologies

The Pedrollo 4SR2-39 hydraulic section is the foundation that ensures the highest efficiency and exceptional durability of the pump. Its patented design is specifically optimized for flawless operation in well conditions where sand is present. The innovative front insert, equipped with the axial impeller movement function, actively counteracts the penetration of even the smallest abrasive particles into critical mechanisms, substantially increasing reliability and extending the pump's service life. Numerous tests and trials have confirmed the absolute reliability of this hydraulic section, demonstrating its ability to operate continuously without failures caused by sand clogging.

Areas of Application and Installation Rules

The Pedrollo 4SR2-39 hydraulic section is designed for installation in wells with a minimum internal diameter of 100 mm (4 inches). It is perfectly compatible with two types of highly efficient Pedrollo submersible electric motors, ensuring optimal operating characteristics.

Pumping systems equipped with the Pedrollo 4SR2-39 hydraulic section successfully solve a wide range of tasks:

Automated water supply: for large industrial and agricultural facilities, as well as urban water supply systems.

Large-scale irrigation: efficient watering of extensive agricultural lands and large horticultural farms.

Industrial washing equipment: reliable water supply for industrial complexes where high pressure and volume indicators are required.

System pressure boosting: enhancing pressure in municipal and industrial water supply networks.

Fire safety systems: ensuring a critically important, powerful, and stable water flow in emergency situations.

Installation of the pump with this hydraulic section is permissible in both horizontal and vertical positions. For vertical installation, it is strongly recommended to use a safety cable, passed through the special eyelets provided on the hydraulic section body, to ensure additional safety. It is crucial to strictly observe a minimum distance of one meter from the bottom of the pump to the bottom of the well.

The Pedrollo 4SR2-39 hydraulic section – is a guarantee of continuous, highly efficient, and durable water supply, capable of ensuring stable operation of your well system even in the most challenging conditions with increased sand content.
