Description of the product
The circulation pumps in the Wilo-Stratos Star-Z series are
coordinated specifically for the operating conditions in domes-
tic hot water circulation systems. Thanks to the choice of
materials and design, they are corrosion-resistant to all the
constituents in the drinking water.
The pump (fig. 1) consists of a hydraulic system and a glandless
pump motor with terminal box. All the rotating parts in the
glandless pump are in contact with the fluid, this is also true for
the motor rotor. A shaft sealing, which is subject to wear, is not
necessary. The fluid lubricates the plain bearings and cools the
bearing and the rotor. Motor protection is not necessary. Even
the maximum overload current cannot damage the motor.
The motor is blocking-current proof.
