Submersible pump 2,5" STM 31 - RTS

Product detailed description

Submersible pumps are essential components in water supply systems for wells, boreholes, and reservoirs. In installations where the water source contains abrasive particles or the borehole is narrow, a robust and modular design is critical. The IBO STM 31 - RTS is designed for use in 2.5-inch diameter bores and is suitable for both new and existing wells, as well as water tanks and collection shafts. It can be integrated into domestic, industrial, and irrigation systems to boost pressure or provide a reliable water source. The modular construction allows for easier servicing, reducing downtime and maintenance costs.

Its resistance to sand and other abrasive materials makes it suitable for environments where water quality is variable. The pump is also appropriate for small and medium fire protection stations and domestic water supply systems. The 20 m power cable length provides flexibility in installation depth and positioning within the water source.

The maximum head of 85 m and flow rate of 45 l/min make this pump suitable for applications requiring high pressure and moderate flow. The 230 V power supply is standard for single-phase systems, and the 20 m cable length allows for installation in deep or narrow sources. The dimensions of 143 cm in length and 6.35 cm in diameter ensure compatibility with 2.5-inch bores.Installation and connection To install the IBO STM 31 - RTS, the pump must be lowered into the water source using a suitable cable or lifting system. The 20 m power cable should be connected to a 230 V power supply with appropriate circuit protection. The pump is designed for submersion in water and must not be operated dry. The modular design allows for disassembly in the event of a fault, reducing the need for full replacement. Common installation mistakes include incorrect cable routing, failure to secure the pump properly, and operating the pump without water, which can cause overheating and motor failure. The pump should be positioned so that the intake is clear of sediment and debris.Compatibility and accessories This submersible pump is compatible with standard water supply and irrigation systems. It can be used in conjunction with pressure tanks, control panels, and filtration units to enhance performance and longevity. Additional components such as check valves, pressure switches, and control systems may be required depending on the specific application. No related products are specified for this model.Technical background for designers The IBO STM 31 - RTS operates on a centrifugal principle, where the impeller generates pressure to move water through the system. The pump's modular design separates the hydraulic components from the motor, allowing for easier maintenance and repair. The floating impeller design reduces wear from abrasive materials, extending the service life. The pump is constructed from materials suitable for submersion in water and is protected against overheating with a thermal fuse. Integration into the system requires consideration of the required flow rate, head, and power supply. The pump is not a monoblock design, which simplifies servicing and reduces downtime.Service and operation Regular inspection of the pump and its connections is recommended to ensure continued performance. The thermal fuse provides protection against overheating, but if the pump fails, it can be disassembled for inspection or repair. No specific service intervals are provided in the technical data. The modular design allows for replacement of individual components rather than the entire unit, reducing maintenance costs. The pump should be operated only when submerged in water to prevent damage to the motor and internal components.Frequently asked questions
