Submersible pump 6SD 25/15 - RTS

Product detailed description

The IBO 6SD 25/15 submersible pump is commonly used in fresh water extraction from wells, boreholes, and storage tanks. It is particularly suited for environments where water contains fine abrasive particles such as sand, which can damage standard pumps over time. This model is often found in agricultural irrigation systems, domestic water supply setups, and fire protection installations where reliability and long-term performance are essential. Installers should consider the pump’s modular construction and hydraulic separation from the motor when planning for maintenance access and replacement procedures.

The pump is frequently deployed in systems requiring high-pressure delivery, such as elevated water towers or pressurized distribution networks. Its ability to handle high head pressures makes it ideal for multi-level buildings or areas with low static water levels. The installation should be planned with sufficient space for submerging the unit fully and for future servicing.

Technical parameters

Installation and connection

Installation begins with verifying the water quality and ensuring the pump is fully submerged. The power cable is 1 m in length, so additional cable or connectors may be needed depending on the depth of the well or tank. The pump connects via standard threaded or flanged fittings—exact dimensions should be confirmed against the system’s piping configuration. Before commissioning, verify the correct polarity of the three-phase supply and test the thermal protection function to ensure the pump will shut down safely in case of overheating. Common installation errors include insufficient submersion depth, incorrect electrical wiring, and failure to secure the cable properly, which can lead to mechanical stress or electrical faults.

Compatibility and accessories

The IBO 6SD 25/15 is compatible with standard water supply systems and can be integrated into pressurized pipelines or header tanks. When installing in a well, a protective cage or filter system may be required to prevent large debris from entering the pump. Additional components such as pressure switches, control panels, and check valves should also be considered to complete the system. While no alternative models are listed here, similar submersible pumps from the IBO range may offer comparable specifications for different applications.

Technical background for designers

This pump operates using a centrifugal mechanism, where the impeller generates kinetic energy to move water through the system. The modular design separates the hydraulic assembly from the motor, reducing the risk of internal damage from abrasion and simplifying repairs. The pump is constructed primarily from durable metal components, which provide resistance to corrosion and wear from abrasive substances in the water. For optimal efficiency, the pump should be installed in clean water with minimal suspended solids, and the system should be sized to avoid excessive cavitation or overloading. Longevity depends on regular inspection of seals and bearings, as well as maintaining proper water levels to prevent dry running.

Service and operation

Maintenance includes inspecting the intake screen or filter to ensure it remains free of blockages and checking the condition of the power cable for signs of wear or insulation breakdown. The thermal overload protection should be tested periodically to confirm it functions correctly. There are no specified service intervals in the provided data, but routine visual inspections are recommended to detect early signs of wear or malfunction. In the event of a fault, the modular design allows for targeted replacement of the affected component rather than the entire unit.

Frequently asked questions

Can the IBO 6SD 25/15 be used in brackish water?
It is not recommended due to potential corrosion effects on the internal components, which are not specified for saltwater conditions.

Is the pump suitable for continuous operation?
Yes, the design supports continuous duty cycles provided the water level remains above the minimum submersion requirement.

Does the pump have built-in dry-run protection?
No, it relies on the operator ensuring adequate water coverage during operation to prevent motor overheating.

Can the pump be retrofitted with a pressure switch?
Yes, a pressure switch can be added externally to automate the pump’s operation based on system demand.
