Table 1: Description of the pump
The high-efficiency pumps Wilo-Yonos MAXO, Wilo-Yonos MAXO-D and Wilo-Yonos MAXO-Z in the version
with flange or threaded pipe union are glandless pumps with a permanent magnet rotor and integrated differ-
ential pressure control.
There is a control module (Fig. 1, item 3) on the motor housing, which controls the pump and provides an SSM
interface. Depending on the chosen application or control function, speed or differential pressure will be con-
trolled. For all differential pressure control functions, the pump continuously adapts to the system's changing
power requirements.
Power limit
The pump is fitted with a power-limiting function, which prevents overload. This may have an operational in-
fluence on the delivery rate.
