Grundfos SQ - SQE Submersible Well Pumps

Grundfos SQ and SQE Submersible Well Pumps: Efficiency and Advanced Technology for Water Supply

Grundfos SQ and SQE series submersible pumps are state-of-the-art solutions for extracting water from boreholes, ensuring a reliable and efficient water supply in domestic and agricultural environments.

Main Features

• Compact Design : At just 3 inches in diameter, the SQ and SQE pumps are ideal for small diameter wells starting at 3 inches.

• Permanent Magnet Motor : Ensures high energy efficiency and optimised performance, reducing electrical consumption.

• Integrated Protection : Equipped with protection systems against dry running, overvoltage, undervoltage, overheating and overload, they ensure a long operating life.

• Soft-Start : Reduces motor wear and minimizes current peaks at start-up, prolonging the life of the pump.

• Constant Pressure (SQE Model) : With its variable speed motor, the SQE pump automatically adjusts performance to maintain constant water pressure, regardless of changing demand.

  
  

Typical Applications

• Domestic Water Supply : Supply of drinking water to private homes.

• Irrigation : Irrigation systems for gardens and small crops.

• Pressure Boost : Increase in water pressure in low pressure systems.

• Liquid Transfer : Movement of water from tanks or cisterns.

FAQ

• What is the difference between the SQ and SQE models?

  The main difference lies in the ability to maintain constant pressure: the SQE model is equipped with a variable speed motor that automatically adjusts the water pressure, while the SQ model operates at a fixed speed.

• Are the SQ and SQE pumps suitable for drinking water?

  Yes, both series are designed for drinking water supply, ensuring safety and hygiene.

• Can these pumps be installed in wells smaller than 3 inches in diameter?

  No, the minimum diameter of the well must be 3 inches (approximately 76 mm) to ensure proper installation.

• What is the maximum operating depth for these pumps?

  The SQ and SQE pumps can operate at significant depths, with heads of up to 200 metres, depending on the specific model.
