Pedrollo 6SR27 / 12-PD submersible apple

For tackling the most ambitious water supply challenges from extremely deep wells, where maximum head, an enormous volume of pumped water, and absolute reliability are required, we present the Pedrollo 6SR27/12-PD submersible pump. This most powerful multi-stage centrifugal electric pump is designed for continuous submerged operation, providing record efficiency and unparalleled durability. It is the ideal choice for the largest industrial enterprises, municipal waterworks, and critically important facilities where a guaranteed and stable water flow is necessary under any, even the most extreme conditions.

Engineering Solutions and Operating Principle

The pumps of the 6SR27 series, which include the Pedrollo 6SR27/12-PD, operate on the principle of multi-stage centrifugal pumps. Liquid sequentially passes through numerous impellers, each rotating on a single drive shaft inside its guide vane diffuser. This process ensures a sequential increase in fluid pressure, which accumulates at each stage, allowing for the achievement of maximum head and flow rate performance, critically important for the most demanding systems. The motor connects to the pump via a bracket whose parameters comply with strict NEMA standards, guaranteeing an absolutely robust, reliable, and sealed connection capable of withstanding extreme operational loads.

Operating Conditions and Installation

The Pedrollo 6SR27/12-PD pump is designed for operation in wells with a diameter greater than 6 inches (150 mm). It is capable of pumping clean water with a sand content of no more than 100 g/m³. For safe and efficient operation, the electric pump must be fully submerged in the well (minimum 50 cm below the water level), and to prevent the intake of bottom sediments, the distance to the bottom of the well must be at least 1 meter. It is critically important to use a stainless steel safety cable, securely fastened through the special eyelets on the hydraulic section body, to ensure maximum safety.

This model is ideally suited for:

Applications in municipal services, agriculture, and industry.

Water supply systems, fire fighting systems, pressure boosting systems, and irrigation.

The Pedrollo 6SR27/12-PD is an uncompromising, high-tech, and extremely powerful piece of equipment, created to provide uninterrupted, efficient, and long-lasting water supply for the most critical, large-scale, and strategic projects.
