Lowering the pump onto an auto coupling
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
and C, the guide claw is mounted on the
outlet flange from the factory.
