With two mechanically controllable switching points, users have a practice-oriented function at their disposal, with which the pressure dependent working points of the pump can be adjusted independently of one another in the simplest manner; the pump can be controlled directly 作者可以由兩個機械控制的開關點實現(xiàn)定位于實際應用的功能,并通過這種功能用最簡單的方式獨立地調整泵的壓力相關工作點:可以直接地控制泵。
