Pedrollo 6SR27 / 10-PD submersible pump

When high head and maximum flow rate are required for water supply from deep wells, the Pedrollo 6SR27/10-PD submersible pump is the ideal choice. This powerful multi-stage centrifugal electric pump is designed for continuous submerged operation, ensuring exceptional efficiency and unparalleled reliability. It is ideally suited for large industrial facilities, extensive agricultural irrigation systems, and fire safety systems with the highest demands for the volume and pressure of pumped water.

Operating Principle and Design Features

The pumps of the 6SR27 series, which include the Pedrollo 6SR27/10-PD, operate on the principle of multi-stage centrifugal pumps. Liquid sequentially passes through a series of impellers and guide vane diffusers. Each impeller, rotating on a single drive shaft inside its diffuser, increases the liquid's pressure, directing it to the next stage. The summation of pressure differentials at each of the numerous stages allows for achieving impressive head and flow rate performance at the outlet of the discharge port. The motor connects to the pump via a bracket whose parameters comply with strict NEMA standards, guaranteeing a strong, reliable, and sealed connection capable of withstanding high operational loads.

Operating and Installation Conditions

The Pedrollo 6SR27/10-PD pump is designed for installation in wells with a diameter greater than 6 inches (150 mm). It specializes in pumping clean water with a sand content of no more than 100 g/m³. For safe and efficient operation, the electric pump must be lowered into the well to a depth where it is fully submerged (minimum 50 cm below the water level). It is important that even during operation, when the liquid level may decrease, the pump remains fully submerged. Furthermore, to prevent the intake of bottom sediments, the distance to the bottom of the well must be at least 1 meter. It is mandatory to use a stainless steel safety cable, secured through the provided eyelets on the hydraulic section body.

This model is ideally suited for:

Applications in industry, agriculture, and municipal services.

Organizing water supply in conjunction with pressure boosting systems.

Irrigation and network pressure boosting.

Use in fire fighting systems.
