Submersible pump 4 SD 10-13 / 400V - RTS

Product detailed description

This submersible pump is commonly used in deep well and reservoir applications where water is drawn from depths exceeding 8 m or transported over long distances. Installers typically encounter this model in new drilling projects, fresh wells, and water storage systems. It is suitable for both domestic and industrial water supply, including fire protection stations and irrigation systems. The modular design ensures easy access to the hydraulic components and allows for straightforward maintenance when necessary. The pump is also equipped with thermal protection to prevent overheating during operation.

Its modular construction separates the hydraulic unit from the motor, which simplifies repairs and replacements without the need to dismantle the entire pump. This makes it a preferred option for installers who require quick troubleshooting and minimal downtime. The inclusion of floating impellers enhances its performance in water sources with high particulate content. The pump is frequently integrated into pressurisation systems, irrigation circuits, and water distribution networks where a stable and efficient flow is required.

Technical parameters

The maximum head of 72 m indicates the pump's ability to lift water to significant heights, making it ideal for elevated tanks or multi-storey buildings. The flow rate of 360 l/min determines how much water can be supplied per minute, which is essential for sizing the pump according to the demand of the system. The 400 V rating means it operates on a three-phase power supply and requires proper phase balance for optimal performance. The cable length of 1 m should be considered when planning the depth of installation and the need for additional cabling if required.

Installation and connection

Before installation, verify that the water source is free of large debris and that the well or borehole is sufficiently sized to accommodate the pump's dimensions (165 x 9.8 cm). The pump should be lowered vertically into the water using a suitable guide pipe or casing to prevent lateral movement and abrasion. Ensure the inlet is fully submerged to avoid air intake and cavitation.

Connect the pump to a 400 V three-phase power supply using a dedicated circuit breaker and protective devices. Check that the power cable is properly secured and insulated against moisture. Confirm that the phase sequence is correct to avoid motor reversal. After installation, perform a dry run test (if allowed by the manufacturer) and monitor the pump for unusual noise or vibration. Avoid running the pump dry for extended periods to prevent damage to internal components.

Compatibility and accessories

This submersible pump is compatible with standard water supply systems, irrigation setups, and fire protection installations. It works well with general-purpose pipes and fittings of appropriate size and material. Additional accessories such as pressure tanks, check valves, and control panels may be required depending on the application. Installers should also consider a separate disinfection process using approved solutions such as PolyWELL when commissioning new or fresh wells to ensure water quality and system longevity.

Technical background for designers

The IBO 4 SD 10-13 employs a centrifugal pumping mechanism, where water is drawn in through the inlet and expelled through the outlet under pressure generated by the rotating impeller. The hydraulic unit is separated from the motor, which reduces mechanical stress and improves durability. The pump housing is constructed from corrosion-resistant materials suitable for continuous immersion in water. The floating impeller design helps reduce wear caused by abrasive particles, ensuring longer operational life in sandy or particulate-rich environments. Integration into the system requires careful consideration of the total dynamic head, flow requirements, and electrical load capacity to optimise efficiency and avoid overloading the motor.

Service and operation

Regular inspections should include checking the integrity of the power cable, verifying the stability of the pump within the well, and monitoring for signs of vibration or noise. The thermal protection feature will automatically shut down the pump in case of overheating, indicating the need for investigation into possible blockages or insufficient cooling. If the pump stops unexpectedly, disconnect the power supply before inspecting the cause. No specific service intervals are provided in the technical documentation; however, routine checks are recommended to ensure continued performance and early detection of potential issues.

Frequently asked questions

Can the IBO 4 SD 10-13 be used in shallow wells?
No, this model is specifically designed for deep well applications and is not suitable for shallow water sources due to its construction and performance characteristics.

Is the pump suitable for intermittent operation?
Yes, the IBO 4 SD 10-13 can handle intermittent operation, but it is important to follow the manufacturer's guidelines to ensure that the pump remains adequately cooled between cycles.

What type of water quality is acceptable for this pump?
The pump is designed for use with clean or slightly turbid water, but it includes enhanced resistance to sand and other abrasive materials found in groundwater sources.

Does the pump require a pressure tank for operation?
A pressure tank is not mandatory, but it is recommended for systems where fluctuating demand could affect the pump’s performance and extend the motor’s lifespan.
