Pedrollo 6SR12 / 15-PD submersible apple

When powerful pressure and reliable supply of clean water from deep wells are required, especially for systems with high demands, the Pedrollo 6SR12/15-PD submersible pump will be your indispensable assistant. This high-performance multi-stage centrifugal electric pump is designed for continuous submerged operation and demonstrates outstanding efficiency and exceptional reliability. It is ideal for use in industrial enterprises, large agricultural complexes, and residential systems with increased water supply requirements, including large-scale irrigation, as well as for fire safety systems.

Construction and Operating Principle:

The pumps of the 6SR12 series, to which the Pedrollo 6SR12/15-PD belongs, are multi-stage centrifugal units whose operating principle is based on the effective summation of pressure at each stage. Impellers, mounted on a single drive shaft, rotate inside guide vane diffusers. These diffusers ensure the movement of liquid from the outlet of one impeller to the suction port of the next. Passing through all consecutively installed impellers, the liquid gains the necessary pressure and exits the pump through the discharge port. This design guarantees a powerful and stable flow. The motor connects to the pump via a bracket whose parameters comply with NEMA standards, ensuring a robust and reliable connection.

Operating Conditions and Area of Application:

The Pedrollo 6SR12/15-PD pump is designed for installation in wells with a minimum diameter of 6 inches (152 mm) and is capable of pumping clean water with a sand content of no more than 100 g/m³. This allows its use where the purity of the pumped medium is important. For safe and efficient operation, the electric pump must be fully submerged in water, even if the liquid level drops during operation, and must be at least 1 meter from the bottom of the well to prevent sediment intake. As a precautionary measure and for reliable pump fixation in the well, it is recommended to use a stainless steel or strong nylon rope, secured through the specially provided holes in the discharge casing.

The Pedrollo 6SR12/15-PD is a powerful and durable piece of equipment, designed to ensure uninterrupted water supply for the most critical systems, where reliability and performance are paramount.
