Submersible pump Pedrollo 4SR8-17

The hydraulic section is the central element of a deep-well pump, performing the main work of lifting water from a well, transporting it, and creating the necessary pressure. The efficiency, service life, and resistance of the pump to external loads depend on the design and characteristics of the hydraulic section. The Pedrollo 4SR8-17 model uses an advanced multi-stage design, consisting of 17 working stages, which ensures a powerful and stable water flow even at great depths. This makes the model an excellent choice for water supply systems with large consumption volumes – both in agriculture and in industry and the municipal sector.

Engineering Features and Design of Pedrollo 4SR8-17

The Pedrollo 4SR8-17 is developed based on the 4SR8 series – high-performance pumps. The model combines increased flow rate with high head, which is achieved through the large diameter of the impellers and optimized water flow within the hydraulic block.

Design features:

17 stages of impellers made of technopolymer with fiberglass reinforcement – resistant to abrasive wear and designed for long-term operation.

Increased flow diameter and high water delivery – ideally suited for systems requiring both head and flow simultaneously.

Stainless steel shaft and diffusers minimize friction and stabilize rotation even under high loads.

Patented sand protection system allows for safe operation with contamination up to 150 g/m³.

Installation versatility – can be mounted both vertically and horizontally (observing installation conditions).
