Optimised ground water extraction
For borehole raw water extraction, municipalities require the highest levels of energy optimisation and resource sustainability, reflected in lower lifecycle costs. Over the years, Grundfos has pioneered numerous innovations that become and continuously influence new standards, and we have experience from a huge installed base of stainless steel submersible pumps and motors.
For example, Grundfos pioneered the implementation of variable speed in pumping operations, and it is innovations such as this that will enable your water supply infrastructure to meet future challenges and regulations.

What is the maximum sand content of pumped water for submersibles?
The maximum sand content of the water may not exceed 50 g/m³. A greater sand content reduces the service life of the pump and increases the risk of pump blockages.
What is a cooling jacket and when should it be used for submersibles?
A cooling jacket, also referred to as a flow generator, ensures that there is always sufficient water flow across the motor surface in order to cool the motor.
In a typical well installation, the pump is surrounded by the walls of the well. The motor is installed below the pump. Because the pump draws in water from below, the water flows along the well walls and over the surface of the motor, cooling the motor in so doing.
If the pump is installed in open water, there will ...
