Pedrollo 6SR18 / 9-PD submersible pump

When high pressure and reliable supply of clean water from deep wells are required, especially for systems with increased demands, the Pedrollo 6SR18/9-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 ideally suited for use in industrial enterprises, large agricultural complexes, and residential systems with high water supply requirements, including large-scale irrigation and fire safety systems.

Construction and Operating Principle:

The pumps of the 6SR18 series, to which the Pedrollo 6SR18/9-PD belongs, are multi-stage centrifugal units. The operating principle is based on the effective summation of pressure at each stage: impellers, installed on a single drive shaft, rotate inside guide vane diffusers, directing the fluid from the outlet of one impeller to the suction port of the next. As it passes through all consecutively installed impellers, the fluid 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. The galvanized steel casing ensures durability and corrosion resistance.

Operating Conditions and Area of Application:

The Pedrollo 6SR18/9-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. For safe and efficient operation, the electric pump must be fully submerged in water (at least 50 cm from the surface), and at least 1 meter from the bottom of the well to prevent sediment intake. It is recommended to use a stainless steel or strong nylon rope, secured through the specially provided holes in the discharge casing. The maximum temperature of the pumped water is +35ºC.

The Pedrollo 6SR18/9-PD is a powerful and durable piece of equipment, designed to ensure uninterrupted water supply for the most critical systems, where reliability and performance with low energy consumption are paramount.
