Pedrollo 6SR27/8-PD submersible pump

For stable and powerful water supply from deep wells, where efficiency and durability are critically important, choose the Pedrollo 6SR27/8-PD submersible pump. This high-performance multi-stage centrifugal electric pump is designed for continuous submerged operation and demonstrates the highest 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 a versatile choice for demanding applications in the municipal, agricultural, and industrial sectors.

Operating Principle and Design Features

The 6SR27 series pumps, which include the Pedrollo 6SR27/8-PD, operate on the principle of multi-stage centrifugal pumps. Impellers, located 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 gradually builds up pressure, which accumulates at each stage, creating a powerful and stable head at the pump outlet. The motor connects to the pump via a bracket whose parameters comply with NEMA standards, guaranteeing a strong and reliable connection.

Installation Conditions and Area of Application

The Pedrollo 6SR27/8-PD pump is designed for operation in wells with a diameter greater than 6 inches (150 mm). For safe and efficient operation, the electric pump must be lowered into the casing to a depth where it is fully submerged in water (minimum 50 cm below the water level), even if its level drops during operation. It is also important to maintain a distance of at least 1 meter from the bottom of the well to prevent the intake of bottom sediments. 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.
