Pedrollo 6SR18 / 15-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 6SR18/15-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 critical facilities where a guaranteed and stable water flow is necessary under any, even the most extreme conditions, including high-performance irrigation and fire safety systems.

Engineering Solutions and Operating Principle

The pumps of the 6SR18 series, of which the Pedrollo 6SR18/15-PD is the pinnacle, 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. 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. The casing made of durable galvanized steel reliably protects against corrosion.

Operating Conditions and Installation

The Pedrollo 6SR18/15-PD pump is designed for operation in wells with a minimum diameter of 6 inches (152 mm) and 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 (at least 50 cm from the surface), and the distance to the bottom of the well must be at least 1 meter to prevent the intake of bottom sediments. It is critically important to use a stainless steel or nylon safety cable, securely fastened through the specially provided holes on the discharge casing, to ensure maximum safety. The maximum temperature of the pumped water is +35ºC.

The Pedrollo 6SR18/15-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, all with low energy consumption.
