Pedrollo 6SR44 / 9-PD submersible apple

When record head and uninterrupted water supply from deep wells are required, especially for the most demanding industrial systems, the Pedrollo 6SR44/9-PD submersible pump is the optimal choice. This powerful submersible borehole electric pump from an Italian manufacturer, thanks to the unique design of its hydraulic section and specially selected materials (stainless steel, nickel-plated cast iron, special rubber, and technopolymer), guarantees uninterrupted clean water supply, reliably protecting against seizing even with up to 100 g/m³ of abrasive impurities (sand, metals).

Operating Principle and Design Features

The pumps of the Pedrollo 6SR44 series are multi-stage centrifugal electric pumps, designed for continuous submerged operation. Their operating principle is based on the efficient summation of pressure: impellers, mounted on a single drive shaft, rotate inside guide vane diffusers, directing the fluid flow to the next stage. Passing through all consecutively installed impellers ensures the creation of a powerful and stable head at the discharge port. The motor connects to the pump via a bracket whose parameters comply with NEMA standards, providing a strong and reliable connection. Installed intermediate bearings further reduce the risk of breakdowns, and a special design allows the pump to be installed even in crooked boreholes, which significantly simplifies installation in challenging conditions.

Area of Application and Advantages

The Pedrollo 6SR44/9-PD pump is ideally suited for pumping water from boreholes and wells, demonstrating high performance and exceptional reliability. It can be successfully applied in the municipal, agricultural, and industrial sectors for:

Water supply to residential homes and enterprises.

Irrigation and watering of gardens and vegetable patches.

Water supply to fountains.
