INSTALLATION
1.
Excavate the pit taking into account the following points:
• Pump chamber height
• Inlet pipe depth
• Connection port DN 150 or DN 200 height
• Underlay approx. 300 mm
• Levelling layer approx. 100 mm
• Pump cover height
• Pump chamber extension height, max. 500 mm
• The pit diameter on the ground must be 2 m larger than the pump
chamber diameter.
• Observe the applicable regulations for earthworks in underground
engineering and road building (slope angle, installation).
• If required due to the ground water level, the pit must be protect-
ed using a ground water drawdown.
NOTE:
If a class D400 pump cover is to be used, a load distribution plate
must also be installed. To do this, the additional height of 300 mm
and the corresponding substructure must be taken into account.
2.
Check the floor of the pit for bearing capacity.
3.
Install the load-bearing mineral mixture underlay properly and seal it
(Dpr 97%).
4.
Add a levelling layer of sand approx. 100 mm thick and level off.
5.
Prepare the onsite inlet, venting and pressure pipes.
6.
Install the pump chamber in the pit, align the connections with the
onsite piping and drive in evenly.
The ground fins must sink completely into the levelling layer.
7.
Check the plumb-vertical alignment and position of the pump
chamber, including the height of the pump cover and any pump
chamber extension, against the surrounding surface level and adjust
if necessary.
5.2.4. Setting up pipe connections
Fig. 4: Preparing pipe connections
Install and lay all pipes so that they are stress-free.
1.
Cut out the selected connection ports for the inlet and venting pipe
and remove burrs.
2.
Lay the piping with a downward slope to the pump chamber and
connect to the opened connection ports with a KG sleeve using
lubricants.
NOTE:
For easier laying of the electrical connection cables (pump/level
control device) max. 30° pipe bends are to be used in the onsite
ventilation line and a tie-rod should be fitted.
3.
Connect the onsite pressure pipe to the pressure connection using
clamp bolting and ensure frost-proof routing.
4.
Perform a leak test in accordance with the applicable regulations.
5.2.5. Installing the pump chamber extension – when using the A15 and
B125 pump cover
CAUTION!
The max. installation depth of 2750 mm including extension,
concrete adjusting rings and pump cover may not be exceed-
ed. Otherwise, deformation or cracks in the body of the pump
chamber could occur.
