Domestic waterworks with submersible pump 3 SQIBO - 0,75/50l

Product detailed description

This domestic water system with a submersible pump is designed for installations requiring a continuous and stable water supply from deep wells or reservoirs. It is commonly used in private homes, summer cottages, schools, and agricultural facilities. The system integrates all essential components—pump, pressure tank, control switch, and piping—into a single unit for efficient and straightforward setup. Installers typically encounter this system in off-grid or rural settings where municipal water supply is unavailable or unreliable. The unit ensures consistent pressure and flow while reducing the need for additional components.

The 3 SQIBO - 0,75/50l system is particularly suited for installations where the water source is located more than 8 m below ground level. The compact design allows for easy integration into existing plumbing layouts, and the included accessories ensure minimal configuration during commissioning. The system supports both potable and non-potable water applications, making it versatile for various domestic and utility purposes such as irrigation and garden watering.

The maximum flow rate of 40 l/min and head capacity of 115 m make this pump ideal for deep well or borehole applications. The 230 V power requirement ensures compatibility with standard household electrical systems. The 15 m cable length provides sufficient reach for most well configurations. The overall dimensions and weight should be considered when assessing space constraints and transport logistics during installation.

Installation and connection

Begin by positioning the pump at the bottom of the well or water source, ensuring the intake is fully submerged. Connect the inlet using the provided 1" coupling and check for secure sealing. The pressure tank should be mounted vertically to maintain proper air/water separation. Ensure the pressure switch is correctly set between cut-in and cut-out pressures according to the tank’s specifications. Connect the pump cable to the switch and verify all electrical connections are properly insulated and grounded. A check valve must be installed in the discharge line to prevent backflow and protect the pump from sudden pressure drops. Common installation errors include incorrect pressure switch settings, improper tank orientation, and failure to secure all fittings, which can lead to leaks or system inefficiency.

Compatibility and accessories

This system is compatible with standard plumbing systems using 1" threaded connections. The included components allow for immediate deployment, but additional fittings such as ball valves or adapters may be required depending on the specific layout. It is recommended to pair the system with a pressure regulator or expansion vessel if integrated into a closed-loop system. No related products are specified for this model.

Technical background for designers

The submersible pump operates on a centrifugal principle, drawing water through the intake and discharging it via the outlet. Constructed with durable materials to withstand immersion in water, the pump is designed for long-term performance in corrosive environments. The pressure tank stores water under compressed air, allowing for steady delivery even during low-demand periods. The system’s efficiency depends on the correct matching of pump capacity to the water source and the stability of the electrical supply. Overloading the pump beyond its rated flow or head can lead to premature wear and reduced service life.

Service and operation

Periodic inspection of the pressure tank’s air pressure and the integrity of all seals and connections is recommended to maintain optimal performance. Check the electrical connections for signs of corrosion or overheating. No scheduled service intervals are specified in the documentation. In case of unusual noise or reduced flow, inspect the pump for blockages and verify the check valve is functioning correctly. Always disconnect the power before performing any maintenance.

Frequently asked questions

Can the system be used for both drinking and irrigation purposes?
Yes, the pump is suitable for potable and non-potable water applications, depending on the water quality and local regulations.

Is it possible to connect the pump to a solar power system?
A 230 V pump requires a stable electrical supply. Solar-powered installations would need an appropriate inverter and battery system to match the voltage requirements.

What should be checked if the pump does not start?
Verify that the power supply is active, the pressure switch is correctly set, and all electrical connections are secure and free from damage.

Can the pressure tank be replaced with a different size?
Yes, but the tank should have a similar working pressure range to ensure compatibility with the pump and switch settings.
