Electric submersible pumps with float switch With external sensor

AgriEuro's offers on the best submersible pumps with external float switch

When it comes to draining or transferring water from cisterns, wells, or tanks, choosing the right submersible pump makes the difference between efficient work and one complicated by technical issues. One of the most common causes of interruptions or malfunctions is the device’s automatic activation system. In tight spaces or areas with internal obstructions, a traditional float can easily get stuck, preventing the pump from starting or stopping. This poses a risk of damage to the machine or improper drainage of the area.

To address these issues, electric submersible pumps with an external sensor float switch offer a reliable and practical solution. The float is not mounted directly on the pump body but is externally connected via a cable: this allows for more flexible installation, free from obstructions, and greater accuracy in water level control. Automatic start and stop become more secure, even in confined or uneven spaces.

These pumps are ideal for those who need practical solutions for draining flooded rooms, irrigation, or use in deep cisterns. Operation is simple: once submerged, they activate automatically based on the water level detected by the external sensor. They are designed for a wide range of users, from gardening enthusiasts to semi-professionals working on residential or agricultural systems.

The external sensor float feature expands its range of applications, improving precision, reliability, and safety during operation.

Main technical features of submersible pumps with external float switch

On AgriEuro, you can select electric submersible pumps with an external float switch by applying specific technical filters. This function allows you to accurately identify the most suitable model based on installation needs, water type, and the depth of the well or cistern. Each pump in this category features an external sensor float, offering greater operational freedom than integrated floats. Technical parameters vary to suit different usage levels, from hobby use to semi-professional applications.

Here is a summary of the main selectable technical features:

• Power supply: all pumps are electric, designed for use with a standard power outlet. Startup is immediate and does not require complex operations.
• Application: models are available for clear water or dirty water. Clear water pumps are suitable for clean liquids without residues; dirty water pumps can handle suspended solid particles.
• INOX casing: many models feature a stainless steel body, which ensures long life and high resistance to corrosion, even in humid or acidic environments.
• For deep wells: some models are designed for use in cisterns or wells with significant depth. The structure is optimized to ensure efficiency at greater submersion levels.
• Maximum flow rate from 3800 to 25000 l/h: flow rate indicates the water volume moved per hour. This is a useful parameter to evaluate the pump’s operating speed.
• Maximum head from 4.5 to 65 m: this value indicates the maximum height the pump can push water. It is essential for vertical installations or where elevation differences exist.
• Maximum submersion depth from 5 to 22 meters: specifies how deep the machine can be safely submerged while maintaining stable performance.

When to use a submersible pump with external float switch?

The submersible pump with external float switch is used to extract water from wells, cisterns, or flooded rooms, managing automatic start and stop via the external sensor. Its main feature is the separated float position, which enables more accurate water level control and reduces malfunction risk in tight spaces or where there are internal obstructions. This system offers greater reliability, especially when traditional integrated float systems are unsuitable.

Practical usage examples include:

• Emptying underground cisterns: the external float allows activation even in narrow and deep cisterns where a traditional float could get stuck;
• Irrigation from domestic wells: the high head and deep submersion capability make these pumps suitable for pushing water over long distances or uphill;
• Removing rainwater from tanks or reservoirs: the ability to handle clear or slightly dirty water allows usage with collected rainwater;
• Draining flooded technical rooms or basements: automatic activation with the external float prevents the need for constant manual intervention in case of repeated water ingress;
• Semi-professional agricultural applications: the high hourly flow rate allows fast water transfer from one area of the system to another.

These pumps are suitable for hobby and semi-professional use levels, thanks to solid construction quality and medium-level performance. They are not suited for continuous operation in intensive production environments where professional-grade or industrial machines are required.

Why buy submersible pumps with external float switch?

Submersible pumps with external float switch offer a range of technical advantages that make them a smart choice for a variety of needs. Every design element is built to enhance functionality in complex environments such as narrow cisterns, deep wells, or tanks with internal obstructions. The external sensor enables precise automation, reduces manual intervention, and extends the pump’s service life.

Key benefits include:

• Greater reliability in confined spaces: the external sensor float doesn’t get stuck against walls or internal obstacles, ensuring automatic activation even in tight environments;
• Precise automatic operation: water level control is managed by a separate sensor, maintaining more consistent start/stop thresholds compared to traditional models;
• High submersion depth: available models reach up to 22 meters in depth, making them suitable for deep wells or underground cisterns;
• Wide range of head and flow rates: the selection includes models with heads up to 65 meters and flow rates up to 25,000 l/h, adapting to system types and water volumes;
• Durable INOX construction: many models feature stainless steel casing, offering strong protection against corrosion and long-term wear even in humid settings.
