Pressure vessel AQUA OLA 50l, horizontal

Product detailed description

The AQUA OLA 50L horizontal pressure vessel is commonly installed in residential and light industrial settings where reliable water storage and pressure stabilisation are required. It integrates into domestic water supply systems, pumping stations, and closed-loop applications where water demand fluctuates. Installers typically use this tank in conjunction with submersible or surface pumps, ensuring the system operates within the tank’s pressure limits. The tank’s horizontal orientation allows for space-efficient installation in mechanical rooms or utility areas.

As part of a pressurised water system, the tank helps reduce the frequency of pump cycling, which prolongs the life of the pump and other components. The EPDM bladder ensures compatibility with potable water, making it suitable for drinking water applications. The tank’s internal design prevents water from coming into direct contact with the steel shell, reducing corrosion risks and maintaining water quality over time.

Technical parameters

Installation and connection

Installation begins with positioning the tank horizontally in a stable location, ensuring proper clearance for maintenance access. The tank connects to the system via threaded ports, typically using compression fittings or flanged connections depending on the pump or control system. It is essential to verify that the pump’s maximum discharge pressure does not exceed the tank’s 6 bar limit to avoid over-pressurisation.

• Connect the inlet/outlet port to the pump or distribution line using appropriate pipe fittings (thread type specified in the installation manual).
• Install a pressure switch or regulator to control the pump’s activation based on system demand.
• Before commissioning, ensure the tank’s internal air pressure matches the system’s baseline pressure (typically 2 bar initially).
• Check for leaks at all joints and ensure the tank is securely mounted to prevent vibration-related damage.

Common installation errors include connecting the tank to a pump with higher-than-rated pressure output, which can cause bladder rupture or tank failure. Another mistake is neglecting to bleed air from the system before filling, which can lead to incorrect pressure readings and premature wear.

Compatibility and accessories

This pressure vessel is compatible with all pump types that operate within the 6 bar pressure range. It is often used with submersible pumps, centrifugal pumps, and booster sets in residential and light industrial applications. When installing, ensure that the system includes a pressure switch or regulator to manage pump activation cycles effectively.

Additional components that should be considered during installation include:

• Pressure switch or pressure regulator
• Non-return valve to prevent backflow
• Pipe fittings and valves matching the tank’s port size and thread type

While no specific related products are listed, the tank functions optimally when integrated into a complete water supply system that includes a reliable pump and control mechanism.

Technical background for designers

The AQUA OLA 50L operates on the principle of a diaphragm-type pressure vessel, where the EPDM bladder separates the water from the compressed air chamber. As water enters the tank, it compresses the air, storing energy that helps maintain pressure even when the pump is off. This reduces the frequency of pump starts and stops, improving overall system efficiency and longevity.

The tank’s steel body is designed to withstand internal pressures up to 6 bar, with additional safety margins to account for thermal expansion and transient pressure spikes. The EPDM bladder is resistant to degradation from potable water and maintains flexibility over time, ensuring consistent performance. For optimal integration, the tank should be sized according to the system’s flow rate and demand patterns, with larger tanks providing longer buffer periods between pump cycles.

Key factors affecting the tank’s service life include the quality of the air charge, the stability of the system pressure, and the absence of corrosive elements in the water supply. Regular maintenance, such as checking and adjusting the air pressure, helps extend the tank’s operational life.

Service and operation

Maintenance for the AQUA OLA 50L involves periodic inspection of the internal air pressure to ensure it remains at the recommended level. According to the manufacturer’s guidelines, the air pressure should be checked approximately every six months and adjusted as needed. This is particularly important because the bladder may lose air over time due to minor leaks or temperature changes.

During routine service, the tank should also be inspected for signs of physical damage, such as dents or corrosion on the outer shell. If the tank is part of a larger system, the pressure switch and associated controls should be tested to confirm they respond correctly to pressure fluctuations.

When adjusting the air pressure, the tank must be drained completely before using a standard pressure gauge and air pump. After recharging, the system should be refilled and monitored for normal operation. If the tank fails to maintain pressure or shows signs of internal leakage, it should be replaced immediately to avoid system downtime.

Frequently asked questions

Can the AQUA OLA 50L be used with a submersible pump?
Yes, the tank is compatible with submersible pumps provided the pump’s maximum discharge pressure does not exceed the tank’s rated pressure of 6 bar.

Is the EPDM bladder suitable for potable water?
Yes, the bladder is specifically designed for potable water and complies with relevant standards for water contact materials.

How often should the air pressure be checked?
It is recommended to check and adjust the internal air pressure approximately every six months to maintain optimal performance.

What happens if the tank is over-pressurised?
Over-pressurisation beyond 6 bar can cause the bladder to rupture or the tank to fail. The tank is not designed to handle pressures exceeding its rated maximum.
