Pedrollo 6SR44 / 3-PD submersible apple

Looking for a powerful and reliable submersible pump for your water supply system? The Pedrollo 6SR44/3-PD submersible pump is a highly efficient multi-stage centrifugal electric pump, developed by the Italian manufacturer for continuous submerged operation. It is ideally suited for pumping clean water with a sand content of no more than 100 g/m³, making it a versatile choice for a wide range of tasks. Thanks to its high efficiency and exceptional reliability, this model finds successful application in the domestic, agricultural, and industrial sectors.

Operating Principle and Design Features

The Pedrollo 6SR44 series pumps operate on the principle of multi-stage centrifugal units. Impellers, mounted on a single drive shaft, rotate inside guide vane diffusers. This design ensures sequential fluid movement, where each pumping stage adds its own pressure differential, cumulatively with the previous ones. This approach guarantees the creation of a powerful and stable head at the pump outlet. The motor connects to the pump via a bracket whose parameters comply with NEMA standards, providing a reliable and sealed connection. High-quality materials are used in the manufacturing of the pumps: stainless steel, nickel-plated cast iron, special rubber, and technopolymer, which ensures durability and resistance to abrasive particles.

Installation and Area of Application

Pedrollo 6SR44 pumps are designed for installation in wells with a diameter greater than 6 inches (150 mm). For optimal and safe operation, the pump is lowered into the casing until fully submerged (minimum 50 cm below the water level and 1 m from the bottom of the well), taking into account the dynamic water level in the well. During installation, it is recommended to secure the pump with a stainless steel cable, passing it through the special eyelets on the hydraulic section body.

This model is ideally suited for:

▪️Water supply to residential homes and cottages: for creating a comfortable and uninterrupted water supply system.

▪️Irrigation of gardens and vegetable patches: ensures efficient watering.

▪️Use as part of automatic water lifting stations: for stable water supply.

▪️Fire protection systems: for ensuring the necessary water pressure in emergency situations.

The Pedrollo 6SR44/3-PD is a reliable, productive, and durable piece of equipment that will provide uninterrupted and efficient water supply for a variety of needs.
