Domestic waterworks IBO WZI 750 / 80l

Product detailed description

This domestic waterworks system is suitable for small to medium residential properties requiring a reliable water supply from wells or boreholes. The system is commonly used in detached houses, cottages and small agricultural buildings where a stable water pressure and flow are required for domestic use. The unit is designed for continuous operation and is ideal for properties where water needs to be drawn from a source up to 8m in depth. The pump automatically activates when water pressure drops, ensuring a consistent supply without manual intervention. The pressure tank maintains a steady pressure and reduces the frequency of pump cycling, extending the system's lifespan.

Installation typically involves connecting the pump to the water source, fitting the pressure tank into the system and ensuring proper electrical connections. The compact dimensions and lightweight design allow for flexible installation in utility rooms, basements or dedicated pump houses. The system is particularly suited for seasonal or occasional use, although for continuous operation, stainless steel-bodied pumps are recommended to prevent corrosion in aggressive water conditions. The system is not intended for high-demand applications such as large households or commercial use.

The maximum flow rate of 50 l/min and a head of 60m are critical for determining the suitability of this system for a given application. The 80L pressure tank ensures a buffer of stored water, reducing the frequency of pump activation and maintaining stable pressure. The 230V electrical supply is standard for residential applications, and the 0.5m inlet cable length should be considered when planning the electrical connection. The overall dimensions of 80x45x85 cm are important for ensuring sufficient space for installation and maintenance.

Installation and connection

The installation process begins with connecting the pump to the water source using the included flexible hose with a 70cm length and elbow fitting. The pump must be positioned with the suction head not exceeding 8m to ensure self-priming capability. The pressure tank is connected to the pump via standard pipe fittings, and the system must be tested for leaks before operation. The electrical connection requires a dedicated 230V supply with proper earthing. It is essential to verify that the water source is free of large debris to prevent pump damage. Common installation mistakes include incorrect positioning of the pump relative to the water level, insufficient space for maintenance access and failure to secure the system against vibration.

Compatibility and accessories

The AQUA OLA WZI 750 / 80L is compatible with standard domestic plumbing systems and can be integrated with additional components such as pressure switches, filters and expansion vessels for enhanced performance. For complete system functionality, it is recommended to install a pressure switch to control the pump's operation and a filter to protect against sediment. The system is not supplied with a pressure gauge, so one may need to be added for monitoring. Accessories such as check valves and non-return valves are also recommended to prevent backflow and maintain system efficiency. Related products such as pressure switches and filters should be selected based on the system's flow rate and pressure requirements.

Technical background for designers

The system operates on a self-priming principle, allowing the pump to draw water from the source without the need for manual priming. The pump is constructed with materials suitable for general water conditions, although for aggressive or high-iron water, stainless steel-bodied alternatives are recommended. The pressure tank is a horizontal model with a 80L capacity, designed to store water under pressure and reduce the frequency of pump activation. The system's efficiency is influenced by the water source's depth, the quality of the water and the integrity of the plumbing connections. Proper sizing of the pressure tank and pump is essential to ensure stable pressure and prevent excessive wear on the pump motor.

Service and operation

The system is designed for low-maintenance operation, with no scheduled service intervals required. Regular checks should include verifying the pressure in the pressure tank and ensuring that the pump is free of debris. The system should be inspected for leaks and proper operation of the pressure switch. If the pump fails to start or the pressure drops unexpectedly, the system should be shut down and inspected for blockages or electrical faults. The pressure tank should be drained periodically to remove sediment and maintain optimal performance. The system is not designed for high-frequency use in aggressive water conditions, and for such applications, a stainless steel-bodied pump is recommended.

Frequently asked questions
