Domestic waterworks IBO WZI 750 / 24l

Product detailed description

This domestic waterworks system is designed for residential water abstraction from wells and boreholes with suction depths up to 8m. The compact unit combines a self-priming pump with a 24L pressure tank, providing a complete solution for small-scale water supply systems. The system is suitable for permanent installation in residential properties requiring a basic water supply for 4-6 occupants. It supports applications including potable water supply, irrigation boosting and pressure stabilisation in distribution systems. The system is particularly suited to seasonal or occasional use in domestic settings where high-volume water delivery is not required.

The installation typically involves connecting the unit to a water source and distribution piping. The pump operates automatically, maintaining pressure within the system through the integrated pressure tank. The unit is designed for straightforward installation with standard plumbing connections and electrical supply. The system requires regular inspection of pressure levels and electrical connections to ensure continued operation.

The maximum flow rate of 50 l/min and 60m head capacity determine the system's suitability for small properties with moderate water demand. The 230V supply voltage requires standard single-phase electrical connection. The 0.5m inlet cable length must be considered during installation planning. The 24L pressure tank size influences the frequency of pump activation and system pressure stability.

Installation and connection

Installation begins with positioning the unit near the water source, ensuring the suction depth does not exceed 8m. The 60cm flexible inlet hose with elbow is connected to the pump inlet using standard thread fittings. The discharge side connects to the distribution system using appropriate pipe sizes. The 230V electrical supply must be connected to a dedicated circuit with proper earthing. Key checks include verifying the suction line is free of leaks and the pressure tank is correctly charged. Common installation errors include incorrect pressure tank pre-charge, improper pump alignment and insufficient electrical protection.

Compatibility and accessories

The system is compatible with standard domestic plumbing systems using threaded connections. Additional components required for complete operation include a pressure switch, pressure gauge and check valve. For seasonal use in corrosive environments, stainless steel pumps are recommended as an alternative. The system requires standard electrical infrastructure with 230V supply and appropriate circuit protection.

Technical background for designers

The system operates on a self-priming centrifugal pump principle, drawing water from the source and pressurising it for distribution. The cast iron pump body provides durability for permanent installation. The pressure tank maintains system pressure between pump cycles, reducing wear on the motor. The system's efficiency depends on correct suction line sizing and proper pressure tank pre-charge. The 50 l/min flow rate is suitable for basic domestic use but may require additional units for higher demand applications.

Service and operation

Routine maintenance includes checking the pressure tank's pre-charge pressure and inspecting electrical connections for corrosion. The system requires no scheduled service intervals but should be inspected periodically for leaks and pressure stability. Key operational checkpoints include verifying the pump starts and stops at the correct pressure points and ensuring the pressure tank maintains consistent pressure levels. The system is designed for low-maintenance operation with minimal service requirements.

Frequently asked questions

Can the WZI 750 be used for irrigation systems?
Yes, the system can be used for irrigation boosting. The 50 l/min flow rate is suitable for small-scale irrigation needs when combined with appropriate control valves.

Is the pump suitable for continuous operation?
The pump is designed for intermittent operation. For continuous use, a higher capacity pump with a larger pressure tank would be required.

What is the maximum suction depth for this system?
The system is rated for a maximum suction depth of 8m. Exceeding this depth may result in reduced performance or failure to prime.

Can the pressure tank be replaced with a larger size?
Yes, the system can be upgraded with a larger pressure tank to reduce pump cycling and improve pressure stability for higher demand applications.
