Control unit

The control unit is the heart of  open-loop control systems. and comprises electrical and electronic components that are wired such that they can execute complex control processes automatically.

Today's control units are based on microprocessors or PLCs basiert. In pumps, they can execute the more complex switching and control processes as they occur in a multiple-pump system in a manner that is compliant with the application. See Fig. 1 Control unit

The pump know-how required is implemented as software based on mathematical algorithms. These pump control units are used for pressure booster systems for example, whereby one or more pumps are started and stopped in line with fluid requirements (pressure, flow rate) to safeguard proper and reliable operation of the system. See Fig. 2 Control unit
