Submersible pump Pedrollo 4SR2-20

Are you looking for a powerful and exceptionally reliable component for your borehole pump, capable of withstanding intensive loads and operating effectively in conditions of high sand content? The Pedrollo 4SR2-20 hydraulic section is an advanced, patented development from the Italian manufacturer, designed for pumping clean water with sand particles up to 150 g/m³. 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 uninterrupted and highly efficient water supply in the domestic sector, industry, and agriculture.

Advantage in Every Detail: Pedrollo Technologies

The Pedrollo 4SR2-20 hydraulic section is the foundation that ensures outstanding performance and long pump life. Its patented design is specifically optimized for operation in conditions where sand is present. The innovative front insert with axial impeller movement actively prevents the penetration of small abrasive particles into the working elements, significantly increasing reliability and extending the pump's operational lifespan. Numerous tests have confirmed the flawless operation of this hydraulic section, demonstrating a complete absence of failures related to sand clogging.

Optimal Application and Installation Parameters

The Pedrollo 4SR2-20 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:

4PD (oil-filled, rewound motor), allowing pump submersion up to 200 meters.

4PS (water-cooled motor), with a maximum submersion depth of up to 100 meters.

Pumping systems equipped with the Pedrollo 4SR2-20 hydraulic section are ideally suited for:

Automatic water supply: for large private homes, cottage settlements, and small industrial facilities.

Large-scale irrigation: efficient watering of extensive agricultural lands, fields, and large garden complexes.

Washing equipment: reliable water supply for industrial installations requiring high pressure and large volumes.

Pressure boosting: increasing pressure in water supply systems for municipal and industrial facilities.

Fire safety systems: ensuring a powerful and stable water flow in critical situations.

Installation of the pump with this hydraulic section is possible in both horizontal and vertical positions. For vertical installation, be sure to use a safety cable, passed through the special eyelets provided on the hydraulic section body, for added safety. It is important to maintain a minimum distance of one meter from the bottom of the pump to the bottom of the well.

The Pedrollo 4SR2-20 hydraulic section is a strategic investment in durable, highly efficient, and uninterrupted water supply, guaranteeing the reliable operation of your well system even in the most demanding conditions.
