Pedrollo 6SR12 / 11-PD submersible apple

For stable, powerful, and reliable water supply from deep wells, where an optimal balance of performance and efficiency is required, choose the Pedrollo 6SR12/11-PD submersible pump. This advanced multi-stage centrifugal electric pump is designed for continuous submerged operation and demonstrates outstanding efficiency and exceptional reliability. It is ideal for use in residential, industrial, and agricultural settings to supply clean water from deep wells with a diameter of at least 6 inches (152 mm), as well as for efficient irrigation systems and fire safety provisions.

Operating Principle and Design Features:

The operating principle of the 6SR12 series pumps is similar to that of other high-quality multi-stage centrifugal pumps. Impellers, mounted on a single drive shaft, rotate inside carefully designed guide vane diffusers. This mechanism ensures sequential fluid movement, where the liquid, upon exiting each impeller, is directed to the suction port of the next. After passing through all consecutively installed impellers, the liquid exits the pump through the discharge port. Each impeller with its corresponding diffuser creates a pumping stage, providing a pressure differential that adds up to the differentials created by previous stages. This guarantees a powerful and stable head at the outlet. The motor connects to the pump via a bracket whose parameters comply with NEMA standards, ensuring a reliable and durable connection.

Installation and Area of Application:

The Pedrollo 6SR12/11-PD pump is designed for pumping clean water containing no more than 50 g/m³ of sand, which highlights its specialization in working with clean sources. For safe and efficient operation, the electric pump must be fully submerged in water, positioned at a depth that guarantees its complete submergence even with a possible drop in water level during operation. At the same time, the distance to the bottom of the well must be at least 1 meter to prevent the intake of bottom sediments. As a precautionary measure and for reliable pump fixation in the well, it is recommended to use a stainless steel or strong nylon rope, secured through the specially provided holes in the discharge casing.

The Pedrollo 6SR12/11-PD is a reliable investment in uninterrupted, efficient, and long-lasting water supply, which will provide your system with high-quality water for many years to come.
