category according to EN206-1. C20/25
8 Mount the motor if it has not yet been installed. Draw the
drilling coupling half flush onto the motor stub and secure on
the feather key with a set screw.
The base frame is designed to accommodate the largest
possible motor for the type of pump used.
If a smaller motor is mounted, the motor bases (blue polymer
concrete) also supplied must be used.
Through bolts or threaded rods cut to a suitable length are
used to secure the motor in place. These must be tightened
with the required tightening torque.
