3 .5 DESIGN AND FUNCTIONALITY
The pumping station is completely assembled so that the pump has to be installed and the connections (inlet, pressure
line, venting line, level control and power supply) be established only.
On the shaft floor, a coupling system is mounted, to which the boltless pump is engaged. A guide pipe, which is attached
to a crossbeam in the shaft neck, to guide the pump when being hung up is available. Engaged by means of a mounted
chain, the pump can be lifted out of the tank without loosening screw connections in the shaft. Depending on the size of
the pump, a lifting gear might be necessary to lift it out. After a long operating time, the pump could attach itself to the
coupling base. To loosen the pump, the chain has to be gently pulled and the chain be shaken until the pump gets loose
from the coupling base. Subsequently, the pump can be carefully pulled out. Too high tensile forces on the chain have to
be avoided in order to prevent damage of the plastic tank. This way, maintenance and repair work on the pump is possible
outside the tank. In order to prevent backflow of the water column being in the pressure line at the ball check valve during
maintenance and repairing work, a shut-off valve is mounted before the check valve in the pressure line.
