Pedrollo 6SR18 / 22-PD submersible apple

Introducing the Pedrollo 6SR18/22-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. If you need to transfer or pump clean water or liquids with an insignificant sand content (up to 100 g/m³) while achieving the highest efficiency with minimal power consumption, then you should consider this model.

Operating Principle and Design Features

The 6SR18 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. For enhanced safety and extended service life, the pump is equipped with a durable galvanized steel casing, which effectively repels moisture and prevents corrosive damage. The pump is designed for compatibility with powerful systems, allowing the pumping of liquids with a small content of abrasive particles.

Area of Use and Installation

The Pedrollo 6SR18/22-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 minimum diameter of 6 inches (152 mm). For optimal performance, the electric pump is lowered into the well 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 or nylon safety cable, secured through the special holes in the discharge casing, to ensure maximum safety.

Key areas of application include:

Accumulation and pumping of water from sumps, deep wells, and reservoirs.

Supplying clean water and generating high pressure in water supply systems.

Efficient pumping of water for large-scale irrigation of gardens and agricultural lands.

Use in fire safety systems and in the sphere of collective water supply. The nominal temperature of the pumped water is approximately +35ºC.

The Pedrollo 6SR18/22-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.
