Pedrollo 6SR27 / 7 / PD submersible apple

For powerful and uninterrupted water supply from deep wells, where maximum efficiency and durability are required, choose the Pedrollo 6SR27/7/PD submersible pump. This high-performance multi-stage centrifugal electric pump is designed for continuous submerged operation and demonstrates outstanding efficiency and exceptional reliability. It is ideally suited for pumping clean water with a sand content of no more than 100 g/m³, making it indispensable for industrial enterprises, large agricultural complexes, and municipal systems.

Operating Principle and Design Features

The 6SR27 series pumps, which include the Pedrollo 6SR27/7/PD, operate on the principle of multi-stage centrifugal pumps. Impellers, mounted on a single drive shaft, rotate inside guide vane diffusers. This mechanism ensures sequential fluid movement: upon exiting each impeller, the fluid is directed to the suction port of the next. As it passes through all consecutively installed impellers, the fluid gains the necessary pressure and exits the pump through the discharge port. This design guarantees a powerful and stable flow. The motor connects to the pump via a bracket whose parameters comply with NEMA standards, ensuring a robust and reliable connection.

Operating Conditions and Area of Application

The Pedrollo 6SR27/7/PD pump is designed for installation in wells with a diameter greater than 6 inches (150 mm). For safe and efficient operation, the electric pump must be fully submerged in water (minimum 50 cm below the water level), and at least 1 meter from the bottom of the well to prevent sediment intake. During installation, it is recommended to secure the pump with a stainless steel cable, passing it through the special eyelets on the hydraulic section body.

This model is ideally suited for:

Industrial applications: for water supply to manufacturing processes.

Agricultural use: for large-scale irrigation systems and farm water supply.

Municipal services: for water supply systems in cities and towns.

Firefighting systems: provides high head for critically important tasks.
