Pedrollo 6SR27 / 20-PD submersible apple

Introducing the Pedrollo 6SR27/20-PD submersible pump – the pinnacle of engineering in the line of high-performance borehole pumps, capable of ensuring uninterrupted water supply from the deepest sources with maximum head. This borehole multi-stage centrifugal electric pump is designed for continuous submerged operation and will become an indispensable part of any large water supply or drainage system.

Operating Principle and Design Features

The 6SR27 series pumps operate on the principle of multi-stage centrifugal units, where each impeller, rotating inside guide vane diffusers, sequentially increases the pressure of the fluid as it passes through all stages. This ensures a powerful and stable head at the outlet, which is critically important for large-scale systems. The motor connects to the pump via a bracket whose parameters comply with strict NEMA standards, guaranteeing a reliable and robust connection.

Area of Use and Installation

The Pedrollo 6SR27/20-PD pump is oriented towards a wide range of applications: from residential and light industrial drainage systems to large-scale facilities. Operation of the pump is possible within wells with a diameter greater than 6 inches (150 mm). For optimal performance, the electric pump is lowered into the casing to a depth where it is fully submerged (minimum 50 cm from the upper water level), even with a possible decrease in liquid level. It is also important that the distance to the bottom of the well is at least 1 meter to prevent the intake of bottom sediments. It is recommended to use a stainless steel cable, secured through the special eyelets on the hydraulic section body, to ensure maximum safety.

Key areas of application include:

Applications in municipal services, agriculture, and industry.

Water supply systems, fire fighting systems, pressure boosting systems, and irrigation.

The Pedrollo 6SR27/20-PD is a high-quality, exceptionally reliable, and energy-efficient piece of equipment, capable of providing uninterrupted and powerful water supply for the most demanding and critical projects
