Pedrollo 6SR18 / 4-PD submersible apple

Are you looking for a reliable and high-performance solution for water supply from large-diameter wells? The Pedrollo 6SR18/4-PD submersible pump is a multi-stage centrifugal electric pump designed for continuous submerged operation. This model is ideal for pumping clean water with low sand content (up to 100 g/m³) from wells with a diameter of at least 6 inches (152 mm). Thanks to its high efficiency and exceptional reliability, the 6SR18/4-PD pump will find widespread application in residential, industrial, and agricultural settings, effectively providing water for various needs, including irrigation systems and fire safety.

Operating Principle and Advantages:

The 6SR18 series pumps operate on the principle of multi-stage centrifugal units. Impellers, located on a single drive shaft, rotate inside guide vane diffusers. This creates a sequential fluid movement, where each pumping stage adds its own pressure differential, cumulatively with the previous ones, ensuring a powerful and stable head at the outlet. The motor connects to the pump via a bracket compliant with NEMA standards, guaranteeing a reliable and sealed connection. The robust galvanized steel casing ensures resistance to moisture and corrosion, significantly extending its service life.

Installation and Area of Application:

For optimal and safe operation, the electric pump must be fully submerged in the well (minimum 50 cm from the upper water level) and located at least 1 meter from the bottom of the well to avoid drawing in bottom sediments. It is recommended to use a stainless steel or nylon rope, secured through the specially provided holes in the discharge casing, for additional fixation. The Pedrollo 6SR18/4-PD pump is ideal for:

Accumulating and pumping water from excavations and wells.

Supplying clean water and boosting pressure in water supply systems.

Pumping water for irrigating gardens and vegetable patches.

Use in fire safety systems and collective water supply.

The Pedrollo 6SR18/4-PD is a reliable investment in stable and long-term water supply, providing high performance with low power consumption and water temperatures up to +35ºC.
