Submersible pump Pedrollo 4SR4-35

If you need a powerful and exceptionally reliable hydraulic section for your borehole pump, capable of providing high head and a significant volume of pumped water, then the Pedrollo 4SR4-35 hydraulic section is the ideal solution. This patented design from the Italian manufacturer is developed for working with clean water containing up to 150 g/m³ of abrasive particles. Thanks to the unique combination of innovative materials and a specially designed 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 industrial, agricultural, and municipal sectors.

Advantage in Every Detail: Pedrollo Technologies

The Pedrollo 4SR4-35 hydraulic section is the key component of the pump, ensuring its high efficiency and durability. Its patented design is specifically optimized for flawless operation in well conditions where sand is present. The innovative front insert with axial impeller movement 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 4SR4-35 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:

With the 4PD motor (oil-filled, rewound), a pump submersion depth of up to 200 meters below the water level is possible.

With the 4PS motor (water-cooled), up to 100 meters below the water level is possible.

Pumping systems equipped with the Pedrollo 4SR4-35 hydraulic section successfully solve a wide range of tasks:

Automated water supply: for large residential properties, cottage communities, and small industrial enterprises.

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 protection 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 4SR4-35 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.
