Submersible pump IBO SDM 3-11

Product detailed description

This submersible pump is commonly used in domestic and industrial water supply systems, particularly in locations where water is drawn from wells, boreholes, tanks, reservoirs, or collection shafts. It is ideal for irrigation, fire protection systems, and water circulation in residential and light industrial applications. The modular design of the IBO SDM 3-11 ensures that the hydraulic and motor components are separated, making it easier to inspect and maintain the unit in the event of a malfunction. This configuration also supports faster repairs compared to monoblock pumps.

When installing the pump, the user should consider the specific conditions of the water source, such as the presence of abrasive particles like sand. The IBO SDM 3-11 is designed with enhanced resistance to these substances, which helps reduce wear and prolong the pump’s service life. The pump is equipped with thermal overload protection, ensuring safe operation under abnormal conditions. The 20 m power cable provides flexibility in positioning the control unit above ground.

The listed parameters are essential for selecting the correct pump for a given application. The maximum flow rate of 105 l/min and a head of 63 m determine the pump’s ability to move water through the system. The 230 V voltage requirement means it must be connected to a standard single-phase supply. The 20 m cable length allows for installation in deeper wells or reservoirs. The dimensions and weight are relevant for handling and fitting within the installation space.

Installation and connection

To install the IBO SDM 3-11, the pump must be lowered into the water source using a suitable support system. The inlet port is typically connected to a pipe via a threaded coupling, ensuring a secure and leak-free seal. The 230 V power supply should be connected to a dedicated circuit with appropriate overcurrent protection. Before commissioning, the installer should verify the correct orientation of the pump and ensure that the intake is fully submerged. Common installation errors include incorrect cable routing, failure to secure the pump properly, and neglecting to check the alignment of the discharge pipe. A thermal overload protector is already built in, but the installer should confirm that the electrical connections are made according to local standards.

Compatibility and accessories

The IBO SDM 3-11 is compatible with standard water supply systems and can be integrated with pressure switches, control panels, and flow meters. For optimal performance, it is recommended to pair the pump with a non-return valve to prevent backflow and a pressure tank to stabilise the system. Additional accessories such as filters or chemical dosing units may be required depending on the water quality and application. No related products are available for this model.

Technical background for designers

The IBO SDM 3-11 operates on a centrifugal pumping principle, where the impeller generates kinetic energy to move water through the system. The separation of the hydraulic and motor components reduces mechanical stress and improves reliability. The pump is constructed using durable materials that resist corrosion and abrasion. The modular design facilitates integration into existing systems and supports easy access for servicing. The presence of abrasive particles in the water can affect the pump’s efficiency and longevity, so the system should be designed to include filtration where necessary. The pump’s dimensions and weight must also be considered when planning the installation location and support structures.

Service and operation

Routine checks should include verifying the integrity of the electrical connections, the condition of the sealing rings, and the absence of unusual noise or vibration during operation. The thermal overload protector will automatically disconnect the pump if overheating occurs. In the event of a fault, the modular design allows the hydraulic section to be removed and inspected without replacing the entire unit. No specific service intervals are provided in the technical documentation, but regular inspections are recommended to ensure continued performance.

Frequently asked questions

Can the IBO SDM 3-11 be used in a new well without prior treatment?
It is recommended to disinfect the well before installation to prevent contamination and improve water quality. The manufacturer suggests using a suitable disinfectant such as PolyWELL.

Is the IBO SDM 3-11 suitable for fire protection systems?
Yes, the pump is suitable for use in small to medium-sized fire protection stations due to its high-pressure capability and reliability.

Can the pump be operated continuously without interruption?
The pump is designed for continuous operation, but it is important to monitor the system for signs of overheating or excessive load. The built-in thermal protection helps prevent damage in such cases.

What is the purpose of the 20 m power cable?
The 20 m cable length allows the pump to be installed at greater depths while keeping the control panel or switchbox above ground level for safety and accessibility.
