Water Applications
In booster systems, vessels are used as buffer tanks to intermediately store the difference between the pumped volume flow and the volume flow actually needed. Vessels are also required to decrease the switch- ing frequency of a pump and reduce peak loads.
The pressurised cushion of air in the gas space is set approximately below the pump’s switch-on pressure. When pressure falls below the switch-on pressure, the pump switches on and pumps water. If consumers remove a relatively small volume of water, the difference in the buffer vessel is stored until the pressurised cushion of air on the switch-off side has compressed and the booster system has switched off. When consumers take water, the interim water is taken from the buffer vessel until the pres- surised cushion of air has fallen to the switch-on pressure and the booster system switches on again.
