Pressure vessel AQUA OLA 100l, horizontal

Product detailed description

This horizontal pressure vessel is commonly installed in domestic water supply systems, pumping stations and industrial facilities where consistent water delivery under pressure is required. It is typically integrated into closed-loop systems where the pump operates intermittently, reducing the frequency of start-stop cycles and prolonging the lifespan of the pump and associated components. Installers working in residential, commercial or light industrial settings will find this unit suitable for applications requiring stable pressure regulation and minimal maintenance.

The unit is particularly suited for use with submersible pumps, surface pumps and booster sets. It ensures a buffer of stored water that allows the pump to operate less frequently, which is critical in systems where energy consumption or mechanical wear is a concern. The unit's horizontal design makes it ideal for installations with limited vertical space, such as utility rooms, basements or compact pump houses. The EPDM bladder inside the tank ensures compatibility with potable water standards and prevents contamination between the water and the steel tank walls.

The technical parameters of the AQUA OLA 100L pressure vessel are essential for proper sizing and system integration. The volume of 100L determines the water storage capacity available to reduce pump cycling. The maximum operating pressure of 6 bar indicates the upper limit of the system pressure the vessel can handle during normal operation. The factory inflation pressure of 2 bar is important for initial setup and should be verified during commissioning. These values help determine whether the vessel is appropriate for the specific pump and system requirements.

Installation and connection

Installation of the AQUA OLA 100L requires secure mounting on a level surface to prevent stress on the connections. The vessel is connected using threaded ports—check the port size and thread type for compatibility with the piping system. Ensure all connections are leak-free using appropriate sealing compounds or gaskets. The vessel should be positioned upstream of the pump or downstream depending on the system configuration. Always follow the manufacturer’s guidelines for orientation and clearance around the tank to allow for inspection and maintenance.

A common mistake during installation is incorrect setting of the pre-charge pressure. The factory pre-charge is 2 bar, and this should be adjusted to match the minimum operating pressure of the pump system. Failure to adjust the pre-charge correctly can lead to inefficient operation or premature wear. Additionally, ensure that the tank is isolated from direct sunlight and extreme temperatures to avoid degradation of the EPDM bladder over time.

Compatibility and accessories

The AQUA OLA 100L is compatible with all types of water pumps and booster systems that operate within the 6 bar pressure range. It is also suitable for use in conjunction with pressure switches, pressure sensors and control panels for automated water supply systems. For optimal performance, it is recommended to pair the pressure vessel with a high-quality pressure switch capable of accurate pressure sensing and switching. Additional accessories such as isolation valves, pressure gauges and filtration units may also be required depending on the system design.

Technical background for designers

This pressure vessel operates on the principle of compressed air acting against a flexible bladder to store and deliver water under pressure. The steel tank provides structural integrity while the EPDM bladder separates the water from the internal air chamber. This design ensures that the water remains free from oxidation and contamination by the metal tank walls. The vessel integrates into the system by acting as a buffer, reducing the number of pump cycles and stabilising pressure fluctuations. The service life of the unit depends on factors such as correct pre-charge pressure, protection from environmental extremes and regular inspection of the bladder for signs of wear or leakage.

Service and operation

Regular maintenance is essential to ensure long-term performance. According to the manufacturer's recommendation, the air pressure inside the tank should be checked approximately every six months. Use a calibrated pressure gauge to verify the pre-charge pressure and adjust it if necessary. Any significant drop in pressure may indicate a leak in the bladder or valve. During inspection, also check for signs of corrosion on the tank exterior and internal components. In case of suspected bladder failure, the unit should be drained and inspected by qualified personnel before re-commissioning.

Frequently asked questions

Can the AQUA OLA 100L be used with a pump operating at 5 bar?
Yes, the tank is rated for continuous operation up to 6 bar, so a pump operating at 5 bar is well within the acceptable range.

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

How often should the air pressure be checked?
It is recommended to inspect and adjust the air pressure in the tank every six months to maintain optimal performance.
