Pedrollo 6SR27 / 4-PD submersible apple

Looking for a powerful and reliable submersible pump for your water supply system? The Pedrollo 6SR27/4-PD submersible pump is a highly efficient multi-stage centrifugal electric pump, designed for continuous submerged operation. It is ideally suited for pumping clean water with a sand content of no more than 100 g/m³, making it a versatile choice for a wide range of tasks. Thanks to its high efficiency and proven reliability, this model is successfully applied in the municipal, agricultural, and industrial sectors.

Operating Principle and Design Features

The 6SR27 series pumps operate on the principle of multi-stage centrifugal units. Impellers, mounted on a single drive shaft, rotate inside 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 a powerful and stable head at the pump outlet. The motor connects to the pump via a bracket compliant with NEMA standards, ensuring a reliable and sealed connection.

Installation and Area of Application

Pedrollo 6SR27 pumps are designed for installation in wells with a diameter greater than 6 inches (150 mm). For optimal and safe operation, the pump is lowered into the casing until fully submerged (minimum 50 cm below the water level and 1 m from the well bottom), with the dynamic water level always taken into account. 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:

Water supply as part of automatic pumping stations: for stable water supply.

Firefighting installations: provides the necessary head for effective fire suppression.

Irrigation and watering systems: for agricultural needs.

Pressure boosting in the network: for maintaining optimal water supply.

Usage Limits
