AQUA OLA 8L Upright Pressure Vessel, Expansion Tank for Water Pumps

Product detailed description

The AQUA OLA 8L pressure vessel with pressure gauge, vertical - upright, serves as a storage tank for pumped water in home water systems, booster and pressure stations, or industrial installations. The AQUA OLA pressure vessel is designed for customers who don't accept compromises or half-measures. Features of the AQUA OLA 8L vertical pressure vessel: The pressure vessel can be paired with any type of pump that does not exceed the vessel's maximum working pressure (6 bar). The pressure vessel contains a rubber (EPDM) bladder approved for drinking water. The factory pre-charge pressure is 2 bar. Generally speaking, the larger the installed pressure vessel, the fewer pump start cycles occur, extending the lifespan of the whole system. For pressure vessels with a rubber bladder, it is recommended to check the air pressure in the vessel roughly once every 6 months. Installing a pressure vessel with a rubber bladder eliminates the need for topping up air in the tank and the increased maintenance this would require. Most frequently asked question: What exactly does Pressure (bar) - PS pressure and MAX pressure mean? This is a relative expression of pressure, usually the pressure inside a closed space (in our case, inside the pressure vessel) relative to the pressure of the surrounding space (often atmospheric). PS is the working pressure and indicates the highest working pressure at which the pressure vessel can function correctly over the long term; it is measured in bar. For example, in households the pressure in the system should not exceed roughly 4 to 4.5 bar, and even these values are already at the limit. In family homes, the pressure system is most often kept below 3.8 bar. Higher pressure settings in the house can cause problems over the long term, affecting various valves and taps in particular. MAX. pressure marked on the pressure vessel indicates the pressure at which the vessel was factory-tested. This tests the overall integrity and strength of the vessel and its welds. The test is carried out without the bladder inserted. WARNING! A pressure of 15 bar must therefore never be applied to the pressure vessel - it would not survive. The bladder would stretch until it completely filled the inside of the vessel and would burst after a few repetitions.
