Description of the pump
The high-efficiency pump Wilo-Yonos MAXO-Z in the
single pump version with flange or threaded pipe union
is a glandless pump with a permanent magnet rotor and
integrated differential pressure control. The choice of
material of the pumps corresponds to the state of the
art, taking into the account the guidelines of the Ger-
man Environment Agency (UBA).
Power limit
The pump is fitted with a power-limiting function
which prevents overload. This may have an operational
influence on the delivery rate.
