Lowering the pump onto an auto coupling
Required tilt angle when the pump is lowered onto the auto
coupling: 5 ° ± 5 °
Submerged installation on auto coupling
Pumps for permanent installation can be installed on a stationary
auto coupling and operated completely or partially submerged in the
pumped liquid.
Before installing the auto-coupling base unit, ensure the quality and
strength of the concrete foundation. See the pull-out strengths
required for anchor bolts at the end of this section. To ensure
adequate pull-out strength, weld the threaded bushings to the steel
reinforcement in the concrete.
For auto-coupling installations, types S (submerged
without cooling jacket) and C (submerged with cooling
jacket), the guide claw is mounted on the outlet flange
from factory.
