Pedrollo 6SR18 / 18 / PD submersible apple

Presenting the Pedrollo 6SR18/18/PD submersible pump – a high-quality product that meets the best performance characteristics. 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 pump or drain clean water or liquids with a negligible sand content (up to 100 g/m³) while achieving high efficiency and low power consumption, then you should pay attention to 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, increases the fluid pressure as it sequentially passes through all stages. This ensures a powerful and stable head at the outlet. The motor connects to the pump via a bracket compliant with NEMA standards. For improved safety statistics, the pump features a durable galvanized steel casing, which repels moisture and corrosive damage, significantly extending its service life. The pump is compatible with more powerful systems that can be used for pumping abrasive liquids.

Area of Use and Installation

The Pedrollo 6SR18/18/PD pump is designed for use in domestic or light industrial drainage systems, as well as for broader tasks. Operation is possible within wells with a diameter of at least 6 inches (152 mm). The electric pump is lowered into the well to a depth where it is fully submerged (minimum 50 cm from the top level of the water), even during operation when the fluid level may decrease, and nevertheless, no less than 1 meter from the bottom of the well. It is recommended to use a stainless steel or nylon safety cable, secured through the holes in the discharge casing, for additional safety.

This model is suitable for the following functions:

Accumulation and pumping of water from sumps, wells, etc.

Supplying clean water and boosting pressure in conjunction with water supply systems.

Pumping water for irrigating gardens and vegetable patches.

Use in fire safety systems, as well as in the sphere of collective use. The nominal temperature of the pumped water is approximately +35ºC.

The Pedrollo 6SR18/18/PD is a high-quality, reliable, and energy-efficient piece of equipment capable of meeting the highest water supply requirements in various applications.
