Description
The Pedrollo 3SR Series is a high-performance 3″ submersible pump designed for use in clean water applications such as domestic supply, irrigation, and small-scale water systems. It is ideal for boreholes with a minimum diameter of 3 inches and delivers efficient water lifting with flow rates up to 7.2 cubic meters per hour and heads up to 267 meters, depending on the model.
Built with precision Italian engineering, the 3SR Series features stainless steel pump components for enhanced durability and corrosion resistance. The impellers and diffusers are constructed from high-grade polymer materials, offering high wear resistance and consistent hydraulic performance.
The motor is a rewindable, oil-filled, two-pole asynchronous type rated at 50Hz and operates at around 2900 RPM. It is available in both single-phase (230V) and three-phase (400V) configurations, with thermal protection and high starting torque for reliable operation even in variable voltage environments.
Designed for continuous operation, the pump can handle water temperatures up to 35°C and sand content up to 150 grams per cubic meter. A minimum water flow rate over the motor is required for cooling, and proper installation is recommended to ensure optimal performance and lifespan.
Compact, efficient, and dependable, the Pedrollo 3SR Series is an excellent solution for narrow boreholes where space and performance are both critical.
