Domestic waterworks IBO WZI 750 / 50l

Product detailed description

This domestic waterworks unit is commonly used in small residential properties, cottages and seasonal homes where a reliable supply of drinking water is required. It is suitable for installation in basements, utility rooms or near the water source. The system is designed for intermittent use, such as in holiday homes or for garden irrigation. The pump operates automatically, maintaining pressure in the distribution system and reducing the need for manual intervention. The pressure tank ensures stable water delivery during short-term demand spikes.

The system is typically integrated with standard plumbing networks and can support various applications including drinking water supply, garden irrigation and pressure boosting in low-pressure systems. Installers should ensure the site has sufficient space for the unit and that the suction conditions comply with the pump’s limitations. The pump is not recommended for continuous operation in aggressive environments due to its plastic housing, which is suitable for general use but not for extreme conditions.

The maximum flow rate of 50 l/min and a pressure head of 60 m make this system suitable for properties with up to six users. The 50-litre pressure tank helps maintain consistent pressure and reduces pump cycling. The 230 V power supply is standard for most European electrical systems, ensuring compatibility with typical household circuits. The dimensions (77 x 71 x 41 cm) and weight (18.45 kg) should be considered when planning the installation location.

Installation and connection

The installation process begins with positioning the unit close to the water source to minimize suction losses. The pump should be mounted on a stable surface to prevent vibration. The suction hose must be connected securely to the pump inlet using the provided 0.5 m power cable and elbow. The discharge side connects to the existing plumbing network via standard fittings. The pressure tank is pre-charged and requires no additional setup unless the pressure setting is adjusted.

• Ensure the suction depth does not exceed 8 m.
• Verify the electrical supply matches the 230 V requirement.
• Check the integrity of all connections and seals to prevent leaks.
• Mount the unit on a level surface to avoid misalignment and vibration.

Common installation mistakes include incorrect orientation of the pump, insufficient sealing at the suction point and failure to secure the pressure tank properly. These issues can lead to air ingress, reduced efficiency and premature wear of components. Always follow the manufacturer’s guidelines for mounting and alignment.

Compatibility and accessories

The WZI 750 / 50l is compatible with standard domestic plumbing systems and can be integrated with additional components such as filters, expansion vessels and pressure switches. For long-term or seasonal use, it is advisable to pair this unit with a frost protection system if installed in unheated areas. Accessories such as non-return valves and pressure gauges may also be required to enhance system performance and safety.

When sourcing additional parts, ensure that all components meet the same pressure and flow requirements to maintain system balance. For example, connecting a higher-capacity tank or a more powerful pump could disrupt the system’s stability and lead to overpressure or underperformance. Accessories should be selected based on the specific needs of the installation site and the expected usage patterns.

Technical background for designers

This system operates on a self-priming centrifugal pump mechanism, which draws water from the source and delivers it to the pressure tank. The pump is housed in a plastic casing, which is suitable for general use but not for aggressive chemical environments. The pressure tank maintains a reserve of pressurized water, reducing the frequency of pump activation and extending its service life.

The pump’s efficiency is influenced by the suction depth, pipe friction losses and the condition of the impeller. Regular inspection of the intake filter and internal components is essential to prevent clogging and maintain performance. The system integrates seamlessly with standard domestic water networks, provided the pressure settings are within acceptable limits. The use of a pressure switch ensures automatic control of the pump based on demand, optimizing energy consumption and reducing wear.

Service and operation

This unit is designed for low-maintenance operation. Routine checks should include verifying the pressure in the tank and inspecting the pump for signs of wear or leakage. The pressure tank should be checked annually to ensure it maintains the correct pressure level. If the tank loses pressure frequently, it may indicate a faulty membrane or valve.

During operation, the pump will cycle on and off depending on the demand for water. If the pump runs continuously or fails to start, it may indicate an issue with the pressure switch or an obstruction in the suction line. In such cases, the system should be inspected for blockages or electrical faults. No scheduled service intervals are specified in the technical documentation, but periodic inspections are recommended to ensure continued reliability.

Frequently asked questions

Can the WZI 750 / 50l be used for continuous water supply?
No, the pump is not intended for continuous operation due to its plastic housing and standard pressure tank.

Is the pressure tank included with the unit?
Yes, the system includes a 50-litre pressure tank as part of the standard configuration.

What is the maximum suction depth for this pump?
The maximum suction depth is 8 m. Exceeding this limit may result in reduced performance or failure to prime.

Can this unit be installed in an unheated room?
It is not recommended for long-term use in unheated areas. Frost damage may occur if the system freezes, especially in the pump and pressure tank.
