Pedrollo 6SR12 / 8-PD submersible apple

Are you looking for a high-performance and reliable submersible pump for your water supply system, capable of operating in large-diameter wells? The Pedrollo 6SR12/8-PD submersible pump is an advanced multi-stage centrifugal electric pump, specifically designed for continuous submerged operation. This model is ideal for pumping clean water with low sand content (no more than 50 g/m³), making it a perfect choice for wells with a diameter of at least 6 inches (152 mm). Thanks to its high efficiency and exceptional reliability, the 6SR12/8-PD pump will find widespread application in residential, industrial, and agricultural settings, effectively providing water for various needs, including large-scale irrigation and fire safety systems.

Technologies and Operating Principle:

The 6SR12 series pumps are based on the proven principle of multi-stage centrifugal action. Impellers, precisely mounted on a common drive shaft, rotate inside specially designed guide vane diffusers. This design ensures sequential fluid movement, where each pumping stage adds its own pressure differential, cumulatively with the previous ones. This approach guarantees the creation of powerful and stable pressure at the pump outlet. The motor, compliant with NEMA standards, connects to the pump via a robust bracket, ensuring a reliable and sealed connection.

Installation and Area of Application:

For optimal and safe operation, the electric pump must be lowered into the well via the discharge pipeline to a depth where it is fully submerged. It is important that, even during operation, when the water level in the well may drop, the pump remains completely submerged (minimum 50 cm from the upper water level). At the same time, to prevent the intake of bottom sediments, the distance to the bottom of the well should be at least 1 meter. As an additional precaution and for secure pump fixation in the well, it is highly recommended to use a stainless steel or strong nylon rope, secured through the specially provided holes in the discharge casing.

The Pedrollo 6SR12/8-PD is not just a pump; it's an investment in a stable, efficient, and long-term water supply that will ensure the uninterrupted operation of your system for many years to come.
