在管道系统中使用压力控制泵，即使流量发生波动，也能保持设备压力恒定。这种系统主要包括供水系统，其中，房屋连接点处的水压必须保持恒定，并且必须确保高层楼宇建筑的顶层具有充足的水供应。

Application description for the scripted commissioning of a SINAMICS G120 for pressure controlled pumps

Pressure-controlled pumps are used in piping systems when pressure at the consumer must be kept constant even when the flow fluctuates. This predominantly involves water supply systems, where the water pressure at the house connection points must be kept constant and where it must be ensured that there is sufficient water in the top floors of high-rise buildings. These so-called pressure boosting stations comprise one or several centrifugal pumps, which using a PID controller control the pressure by changing the speed.

Note
Commissioning of SIMOTICS FD motors is not supported in this version.
When using load side components as output reactors, dv/dt filters and sinusoidal filters, necessary parameter changes have to be done additional.
