Submersible pump 4 SKM 100

Product detailed description

Submersible pumps are essential components in residential water supply systems, particularly in areas where municipal water supply is not available. The IBO 4 SKM 100 is commonly used in narrow boreholes, wells and storage tanks to extract clean water for household use. Installers working in rural or semi-rural environments often rely on this type of pump to ensure a steady water supply. It is suitable for applications where the water is free from solid particles and abrasive substances. The pump can be deployed in depths up to 20 m below the surface level, making it ideal for deep water sources. Its compact design allows it to fit into narrow shafts, while the high head ensures delivery to upper floors or elevated storage tanks.

When installing the IBO 4 SKM 100, it is important to consider the water level fluctuations and the required flow rate. The pump is not intended for continuous operation under high load conditions and should be sized according to the specific application. The maximum number of starts per hour is limited to 20, which must be taken into account during system planning. The pump is typically used in single-phase systems and requires a stable power supply to function efficiently.

Technical parameters

The technical parameters define the performance and limitations of the IBO 4 SKM 100. The maximum flow rate of 40 l/min indicates the volume of water the pump can move under optimal conditions. The head of 60 m means the pump can lift water to a height of 60 m, which is useful for multi-storey buildings or elevated tanks. The 230 V rating specifies the electrical input required, which must match the local power supply. The cable length of 15 m provides flexibility in positioning the pump within the water source. These values are critical for correct sizing and system integration.

Installation and connection

Proper installation is crucial for the reliable operation of the IBO 4 SKM 100. Begin by inspecting the pump for any visible damage and confirming the correct model and specifications. The pump is lowered into the water source using a suitable hoisting mechanism, ensuring it is fully submerged but not in contact with the bottom. The 15 m power cable should be routed to a waterproof junction box, and all electrical connections must be made in accordance with local regulations. The pump must be connected to a 230 V single-phase supply with appropriate fusing and protection devices.

Key installation checks include verifying the water level, ensuring the pump is not cavitating and confirming the flow rate meets the system requirements. Common mistakes include incorrect cable routing, insufficient submersion depth and failure to secure the pump properly. It is also important to avoid overloading the pump beyond its rated capacity, as this can lead to premature wear and reduced efficiency.

Compatibility and accessories

The IBO 4 SKM 100 is compatible with standard residential water supply systems and can be integrated with pressure tanks, control panels and flow meters. Additional components such as check valves and strainers may be required to prevent backflow and protect the pump from debris. The pump does not require specific accessories for basic operation but may benefit from a dedicated control unit for automatic switching and overload protection. When selecting complementary equipment, ensure that the voltage and current ratings are compatible with the pump’s specifications.

Technical background for designers

The IBO 4 SKM 100 operates using a two-pole induction motor with a speed of 2850 rpm, providing sufficient torque for water lifting. The motor is constructed from stainless steel and cooled with mineral oil to ensure thermal stability. The bearings are self-lubricating, reducing the need for regular maintenance. The mechanical seal is made from graphite, offering resistance to wear and leakage. The pump is designed for integration into closed-loop systems where the water is non-corrosive and free from abrasives. The service life and efficiency are influenced by the water quality, operating temperature and frequency of use. To maximise performance, the pump should be operated within its specified limits and protected from extreme conditions.

Service and operation

Regular inspection of the IBO 4 SKM 100 is necessary to ensure continued performance. Key checkpoints include the condition of the power cable, the presence of leaks and the overall operation of the pump. The motor should remain cool during operation, and any unusual noise or vibration should be investigated. The pump does not require scheduled maintenance due to its sealed design and self-lubricating components. However, it is recommended to periodically test the pump under load to confirm its functionality. In the event of failure, the pump should be removed from the water source and inspected for signs of damage or wear.

Frequently asked questions

Can the IBO 4 SKM 100 be used in water temperatures above 35 °C?
No, the pump is designed for water temperatures up to 35 °C. Exceeding this limit may affect the motor cooling and reduce the service life.

Is the IBO 4 SKM 100 suitable for continuous operation?
No, the pump is not intended for continuous use. The maximum number of starts per hour is 20, and extended operation may lead to overheating.

What is the maximum depth the IBO 4 SKM 100 can be submerged?
The pump can be submerged up to 20 m below the water surface. Exceeding this depth may affect the pump’s performance and safety.

Does the IBO 4 SKM 100 require a pressure tank for operation?
No, the pump can operate without a pressure tank. However, a pressure tank may be beneficial for stabilising the water supply and reducing pump cycling.
