Submersible pump 6SD 25/9 - RTS

Product detailed description

Submersible pumps are essential components in water supply systems where direct immersion in the source is required. In residential, agricultural and light industrial applications, these pumps are typically installed in drilled wells, boreholes, storage tanks or collection pits. Installers working with such systems often encounter challenges related to sediment content in water, mechanical stress from frequent start-stop cycles and the need for rapid fault diagnosis and repair. The IBO 6SD 25/9 is engineered to address these concerns through its modular construction and abrasion-resistant components. The pump is particularly suited for environments where water contains sand or other abrasive particles. This makes it suitable for newly drilled wells, older boreholes, reservoirs and collection shafts. Its modular construction ensures that individual components can be replaced without removing the entire unit from the water source, reducing downtime during maintenance or repairs.

The 113 m head and 920 l/min flow rate make this pump suitable for medium to high-pressure applications. The 400 V three-phase power supply is standard for industrial installations. The 1 m supply cable length should be considered when planning the electrical connection and control system layout.

Installation and connection

Before installation, verify that the pump is compatible with the water source depth and diameter. Ensure the power supply matches the 400 V requirement and that the control system includes thermal protection and overload monitoring. Connect the pump using a standard threaded coupling that matches the pipe size in the system. During installation, avoid twisting the inlet cable and ensure secure grounding. Common mistakes include incorrect cable routing, which can lead to insulation damage, and failure to align the pump axis vertically, which can cause mechanical stress on the shaft and bearings.

Compatibility and accessories

This pump is typically used with standard steel or PVC piping systems. For deep well applications, it should be connected to a downpipe or guide rail system to maintain alignment. Additional components such as pressure switches, control panels and check valves may be required depending on the system configuration. Ensure that all electrical connections are made by qualified personnel and that the installation complies with local electrical codes.

Technical background for designers

The IBO 6SD 25/9 operates using a centrifugal pumping mechanism, where the impeller generates kinetic energy to move water through the system. The hydraulic section is separated from the motor, which enhances durability and simplifies maintenance. The pump housing is constructed from abrasion-resistant materials to withstand particulate-laden water. The thermal protection feature prevents overheating in case of dry running or excessive load. When integrating this pump into a system, consider the total dynamic head, including friction losses in the piping and fittings, to ensure optimal performance.

Service and operation

Routine checks should include verifying the integrity of the power cable, inspecting the pump for signs of wear or blockage, and ensuring that the thermal protection device is functioning correctly. If the pump stops operating unexpectedly, check the power supply and control system before attempting any disassembly. No specific service intervals are provided, but regular visual inspections are recommended to identify potential issues early.

Frequently asked questions

Can the IBO 6SD 25/9 be used in municipal water supply systems?
Yes, it is suitable for municipal water supply applications where the water contains abrasive particles and requires high head delivery.

Is the pump suitable for continuous operation?
It is designed for intermittent operation, but can handle continuous use if the system is properly sized and maintained according to the manufacturer's guidelines.

Can the pump be repaired on-site?
The modular design allows for some components to be replaced without removing the entire unit, but major repairs should be carried out by a qualified service technician.

What type of electrical protection is included?
The pump is equipped with thermal protection to prevent motor damage from overheating during abnormal operating conditions.
