Submersible pump 4 SD 8-25 / 400V - RTS

Product detailed description

Submersible pumps are essential components in water supply systems where water is sourced from depths exceeding 8 m or transported over long distances. The IBO 4 SD 8-25 model is commonly used in new or fresh wells, boreholes, reservoirs, and collection shafts. It is suitable for integration into distribution pipelines to increase pressure, as well as for domestic, industrial, and irrigation purposes. The pump is particularly suited for environments where water may contain sand or other abrasive particles, thanks to its design with floating impellers and enhanced resistance to wear.

Installers and technicians often encounter scenarios where a reliable and durable pump is required for continuous operation. The IBO 4 SD 8-25 is designed to meet such demands, with a modular construction that allows for easy disassembly and repair. This feature reduces downtime and maintenance costs, making it a practical choice for installations where system reliability is critical. The pump is also equipped with thermal protection, ensuring safe operation under varying load conditions.

The pump operates at 400 V and delivers a maximum flow rate of 250 l/min with a head of 169 m. These parameters are essential for sizing the pump to match the hydraulic requirements of the system. The 1 m supply cable length must be considered during installation to ensure proper connection to the power source. The dimensions of 243 x 9.8 cm are relevant for assessing space constraints in the well or reservoir. These values are crucial for verifying compatibility with the installation site and for ensuring that the pump can meet the required flow and pressure conditions.

Installation and connection

The IBO 4 SD 8-25 is installed by lowering it into the well or reservoir using a suitable cable or lifting device. The power supply is connected via a 400 V three-phase electrical system, and the 1 m supply cable must be extended as needed. The pump is connected to the discharge pipe using standard thread types, and the connection must be sealed to prevent leaks. It is important to ensure that the pump is fully submerged and that the intake is positioned below the water level to avoid air ingestion. Common installation mistakes include incorrect cable length, improper sealing of the discharge connection, and failure to align the pump with the well casing. These errors can lead to reduced efficiency, mechanical stress, or premature failure.

Compatibility and accessories

The IBO 4 SD 8-25 is compatible with standard water supply systems and can be integrated into both new and existing installations. It is suitable for use with fresh water sources and is not recommended for chemically aggressive or highly contaminated media. To ensure proper operation, the pump should be used with a pressure tank and a control panel for managing flow and pressure. Additional accessories such as check valves, filters, and pressure switches may be required depending on the system configuration. No specific related products are listed for this model, but standard water supply components are typically used in conjunction with the pump.

Technical background for designers

The IBO 4 SD 8-25 operates on a centrifugal principle, with the impeller generating the necessary pressure to move water from the source to the distribution system. The pump is constructed with materials that provide resistance to abrasion and corrosion, making it suitable for environments where water contains sand or other particulate matter. The modular design allows for easy separation of the hydraulic and motor components, which simplifies maintenance and repair. The pump is intended for integration into systems that require a high head and moderate flow rate. Factors that affect service life and efficiency include the quality of the water, the frequency of operation, and the presence of abrasive particles. Proper system design, including adequate filtration and pressure regulation, is essential for maximizing performance and longevity.

Service and operation

The IBO 4 SD 8-25 requires regular inspection to ensure optimal performance. The thermal protection feature helps prevent overheating, but it is still important to monitor the pump for signs of wear or damage. The supply cable should be checked for insulation integrity, and the discharge connection should be inspected for leaks. No specific service intervals are provided in the brief, but routine maintenance is recommended to ensure continued operation. In the event of a failure, the modular design allows for quick replacement of the affected component, reducing downtime and repair costs. It is also recommended to apply disinfection, such as PolyWELL, when using the pump in new or fresh wells to help the water source regenerate and remain clean.
