Pressure vessel AQUA OLA 80l, standing

Product detailed description

Expansion vessels are essential components in pressurised water systems, particularly in domestic and industrial applications where water is drawn from wells or reservoirs. These vessels act as storage units that maintain pressure stability and reduce the frequency of pump activation. In residential pumping stations, industrial water supply systems, or pressure boosting installations, expansion vessels help prevent excessive wear on pumps and valves. The AQUA OLA 80L standing model is suited for systems where a vertical installation is preferred, such as in utility rooms or compact spaces. It is commonly used in conjunction with submersible or surface pumps, where the vessel is sized to match the system’s water demand and pressure requirements.

When designing a water supply system, the correct sizing of the expansion vessel is crucial to ensure efficient operation. The vessel must be selected based on the system’s maximum pressure, the volume of water to be stored, and the pump’s flow rate. The AQUA OLA 80L model is suitable for systems with a working pressure up to 6 bar and is particularly effective in reducing the number of pump start-stop cycles. This contributes to longer system life and reduced energy consumption. The vertical orientation of the vessel also makes it easier to integrate into existing installations where space is limited.

The technical parameters of the AQUA OLA 80L expansion vessel are essential for proper system integration. The 80L capacity ensures sufficient water storage to reduce pump cycling, while the working pressure of 6 bar allows compatibility with a wide range of pump types. The factory pre-charge of 2 bar is set to optimise the vessel’s performance for potable water systems. The dimensions (96 x 42.5 cm) are important for determining the space required during installation. These parameters are key to selecting the correct vessel for a given system and ensuring that it operates within its design limits.

Installation and connection

The AQUA OLA 80L expansion vessel is installed in a vertical position and connected to the water system using standard pipe fittings. The vessel is typically connected between the pump and the pressure switch to stabilise pressure fluctuations. It is important to ensure that the vessel is installed in a location that allows for easy access for maintenance and pressure checks. The connection should be made using appropriate pipe sizes and fittings to avoid flow restrictions. A common mistake during installation is neglecting to check the pre-charge pressure after installation. This can lead to improper operation and reduced system efficiency. Installers should also ensure that the vessel is not subjected to excessive pressure beyond its rated capacity to prevent damage to the bladder or vessel body.

Compatibility and accessories

The AQUA OLA 80L expansion vessel is compatible with a wide range of pump types, including submersible and surface pumps, provided the system pressure does not exceed 6 bar. It is designed for use with potable water systems and features an EPDM bladder that is suitable for drinking water applications. When installing the vessel, it is important to ensure that the system includes a pressure switch and a pressure gauge to monitor system performance. Additional accessories such as isolation valves and pressure relief valves may also be required depending on the system configuration. No specific related products are required for this model, but proper system design and component selection are essential for optimal performance.

Technical background for designers

The AQUA OLA 80L expansion vessel operates on the principle of a diaphragm separating the air chamber from the water chamber. The EPDM bladder is pre-charged with air at 2 bar and expands or contracts as water is drawn from or returned to the system. This helps maintain a stable pressure and reduces the need for frequent pump activation. The vessel is constructed from steel and is designed to withstand internal pressures up to 6 bar. The choice of EPDM material ensures compatibility with potable water and provides resistance to chemical degradation. The integration of the vessel into the system is critical for its efficiency and longevity. Factors such as the system’s flow rate, pump characteristics, and pressure settings all influence the vessel’s performance. Proper sizing and installation are essential to ensure that the vessel functions as intended and contributes to the overall system reliability.

Service and operation

Regular maintenance of the AQUA OLA 80L expansion vessel is important to ensure continued performance. The air pressure in the vessel should be checked approximately every six months to ensure it remains at the factory setting of 2 bar. If the pressure is found to be lower than expected, it should be adjusted using an air pump. It is important to avoid over-pressurising the vessel, as this can damage the bladder or cause premature failure. During routine inspections, installers should also check for signs of corrosion or wear on the vessel body and fittings. If the bladder becomes damaged or the vessel fails to maintain pressure, it should be replaced to prevent system inefficiency or pump damage. No other service intervals are specified for this model, but regular checks are recommended to ensure optimal operation.

Frequently asked questions

Can the AQUA OLA 80L be used with a submersible pump?
Yes, the vessel is compatible with submersible pumps as long as the system pressure does not exceed 6 bar. It is commonly used in pumping stations and well water systems.

What is the factory pre-charge pressure of the vessel?
The vessel is pre-charged with air at 2 bar from the factory. This setting is suitable for most potable water applications and should be maintained during operation.

How often should the air pressure be checked?
The air pressure in the vessel should be checked approximately every six months to ensure it remains at the correct level. This helps maintain system efficiency and prevent pump cycling.

Can the vessel be used in systems with higher pressure than 6 bar?
No, the vessel is designed for a maximum working pressure of 6 bar. Exceeding this limit can cause damage to the bladder or vessel body and should be avoided.
