Pressure vessel AQUA OLA 50l, standing

Product detailed description

Expansion vessels are essential components in closed water systems, particularly in domestic water supply, transfer pumps, and pressure stations. These vessels help stabilise pressure fluctuations and reduce the frequency of pump cycling, thereby extending the lifespan of the system. The AQUA OLA 50L standing vessel is suitable for both residential and light industrial applications. It is commonly used in systems where a compact, vertical design is preferred, such as in basements or utility rooms with limited floor space. The vessel is compatible with a wide range of pump types, provided the system pressure does not exceed the maximum working pressure of the vessel. Installers should ensure that the vessel is correctly sized for the system volume and pump characteristics to optimise performance.

When installing expansion vessels, it is important to consider the system’s hydraulic requirements and the pump’s operating parameters. The vessel should be positioned in a location that allows for easy access for maintenance and inspection. It is also important to ensure that the vessel is not subjected to excessive mechanical stress or thermal variations that could affect its integrity. The AQUA OLA 50L is designed for integration into systems that require a reliable and durable solution for pressure stabilisation and water storage.

The technical parameters of the AQUA OLA 50L expansion vessel are critical for proper sizing and system compatibility. The 50L capacity ensures sufficient water storage to reduce pump cycling, while the maximum working pressure of 6 bar defines the upper limit of the system pressure. The dimensions (75x38 cm) indicate a vertical orientation, which is ideal for installations with limited horizontal space. The working pressure and volume are key factors in determining the vessel’s suitability for a given system. The factory pre-charge pressure of 2 bar is set to ensure optimal operation under typical domestic conditions.

Installation and connection

Installation of the AQUA OLA 50L expansion vessel should follow standard procedures for pressure vessels in closed water systems. The vessel is connected to the system via standard pipe fittings, and the connection size must be verified to match the pump or system requirements. The vessel should be mounted in a stable, upright position to prevent mechanical stress on the bladder or casing. It is important to check the pre-charge pressure before commissioning and to ensure that the system pressure does not exceed the vessel’s maximum working pressure. Common installation mistakes include incorrect orientation, failure to check the pre-charge pressure, and improper securing of the vessel, which can lead to mechanical failure or reduced efficiency.

Compatibility and accessories

The AQUA OLA 50L expansion vessel is compatible with a wide range of pump types and pressure systems, provided the system pressure remains within the vessel’s operational limits. It is suitable for use with submersible pumps, transfer pumps, and pressure boosting systems. No additional accessories are required for basic installation, but it is recommended to include pressure gauges and isolation valves for system monitoring and maintenance. The vessel is not compatible with systems that require higher pressure than 6 bar or that use non-potable water. Installers should also ensure that the system includes appropriate safety devices, such as pressure relief valves, to prevent over-pressurisation.

Technical background for designers

The AQUA OLA 50L expansion vessel operates on the principle of a pre-pressurised bladder that separates the water from the air chamber. The EPDM bladder is designed for potable water and is resistant to chemical degradation and temperature variations. The steel casing provides structural integrity and durability under operating pressures. The vessel is integrated into the system to absorb pressure fluctuations caused by pump operation and thermal expansion. The service life and efficiency of the vessel are influenced by factors such as the frequency of pressure cycles, the quality of the water, and the maintenance of the pre-charge pressure. Proper sizing of the vessel is essential to ensure that it can accommodate the system’s expansion and contraction without excessive pump cycling.

Service and operation

Regular maintenance of the AQUA OLA 50L expansion vessel is necessary to ensure long-term performance. The pre-charge pressure 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 low, it should be adjusted using a suitable air pump and pressure gauge. It is important to avoid over-pressurisation, as this can damage the bladder or casing. The vessel should also be inspected for signs of corrosion, leakage, or mechanical damage. If the bladder becomes damaged or the vessel fails to maintain pressure, it should be replaced immediately to prevent system failure. No other service intervals are specified in the technical documentation.

Frequently asked questions

Can the AQUA OLA 50L be connected to a pressure boosting system?
Yes, the vessel is compatible with pressure boosting systems provided the system pressure does not exceed 6 bar. It helps reduce pump cycling and stabilises pressure fluctuations.

What happens if the system pressure exceeds 6 bar?
If the system pressure exceeds the maximum working pressure of the vessel, the bladder may be damaged, and the vessel may fail. It is essential to ensure that the system pressure remains within the specified limits.

Is the EPDM bladder suitable for potable water?
Yes, the EPDM bladder is specifically designed for potable water and is resistant to chemical degradation and temperature variations.

Can the pre-charge pressure be adjusted after installation?
Yes, the pre-charge pressure can be adjusted using a pressure gauge and air pump. However, it should not be set higher than the factory setting of 2 bar to avoid damage to the vessel.
