Submersible pumps for renewable energy with integrated inverter.
The engine has been specially developed for the system.SQFlex,And it is designed according to the permanent magnet principle with a built-in electronic unit.
The bombsGrundfos SQFlexThey can be very useful in places where we need the pump to work during the night as well, since we can connect it to different sources of energy, such as a wind turbine, batteries, a generator, or even to the electrical grid.
Another advantage it has is thedry well probeBuilt into the pump itself. It allows us to protect the installation and the motor in case our well runs out of water. When the water level is low, below the dry well probe situation, the pump shuts off. It reconnects automatically when the water level rises above it and stays there for 5 minutes.
In a horizontal setup, it is necessary for the water level to be above the pump, and the sensor should be positioned at least 30 to 60 cm above the pump to ensure protection against dry running.
High voltage or low voltage:
When the tension towards the pump is unstable, unwanted voltage "jumps" can occur. The pump will stop if the voltage falls or rises outside the operating range. The motor will start running again automatically when the voltage is within the working range.Grundfos SQFLEX pump.
This can also occur due to an unstable power source or a faulty installation.
Furthermore, the segmented motor stator significantly contributes to high efficiency.
Overload protection:
The motor will stop for 10 seconds. After this time, the pump will automatically try to start again. The overload protection prevents the motor from being damaged, so no external protection is needed for the motor.Grundfos SQFLEX pump.
Protection against high temperature:
The working temperature of theGrundfos SQFLEX pumpIf the temperature exceeds 85°C, the motor will automatically shut off. Once the temperature drops to 75°C, the Grundfos SQFLEX pump motor will restart automatically.
The special features of theGrundfos SQFLEX pump.They ensure easy installation, without the need for unnecessary external protections.
The built-in electronic unit provides a number of advantages to the system.SQFlex,If we compare it with other pumps on the market. The main one is themicroprocessorIntegrated with MPPT.
Thanks to the MPPT function, the pump's operating point is continuously optimized based on the available input power. The MPPT is only available for pumps connected to direct current (DC).
Reliability
The engineMSF 3It has been designed and developed with high reliability in mind, the following characteristics stand out:
The MSF 3 motor is a permanent magnet motor (PM motor) with higher efficiency within the power range compared to a conventional asynchronous motor.
It is protected against power supply transients according to EN/IEC 61000-4-5 (6 kV). In areas with high intensity of lightning strikes, external lightning protection is recommended.
It has an efficient internal circulation system that removes heat from the rotor, stator, and bearings, ensuring optimal operating conditions for the motor.
The wide voltage range for its operation allows the motor to be suitable for any voltage between 30-300 VDC or 90-240 VAC. This feature makes installation and sizing really easy.
