Installation
In order to prevent damage to the machine or serious injury during installation the following points
must be observed:
- Installation work – assembly and installation of the machine – may only be carried out by
qualified persons. The safety instructions must be followed at all times.
- The machine must be inspected for transport damage before any installation work is carried
out .
General information
After pumping water containing lime, clay or cement, flush out the machine with clean water in
order to prevent encrustation and to prevent later break-downs.
If you are using level control, make sure that the minimum water coverage is present. Air pockets
may not be allowed to enter the pump housing or the pipeline system, and they must be removed
with a suitable ventilation system and/or a small inclination of the machine (with a portable instal-
lation). Protect the machine from frost.
Installation types
Possible types of vertical installation for the machine:
- Wet installation with a suspension unit (BA)
- Dry installation (TA)
- Portable installation with a pump pedestal (T)
The operating area
The operating area must be laid out for each machine. You must ensure that lifting gear can be fit-
ted without any trouble, since this is required for assembly and removal of the machine. It must be
possible to safely reach the machine in its operating and storage locations using the hoisting gear.
The machine must be located on a firm foundation.
Electric power cables must be laid out in such a way that safe operation and non-problematic
assembly/dismantling are possible at all times.
The structural components and foundations must be of sufficient stability to ensure safe and func-
tional operation. The operator or the supplier is responsible for the provision of the foundations and
their accuracy in terms of dimensions, stability and strength.
Never let the machine run dry. Therefore, we recommend installing a level control unit or a dry-run
protection system where there are great variations in the level.
Use guide and defector plates for the pumped fluid intake. If the water jet reaches the surface of
the water or the machine, air will be introduced into the pumped liquid. This will lead to unfavor-
able current and pumping conditions. As a result, the machine does not run smoothly and is sub-
jected to higher wear and tear.
Assembly accessories
Swiveling hoisting gear
The maximum bearing capacity must be greater than the weight of the machine, add-on units and
cable. It is essential that the machine can be lifted and lowered without hindrance or endangering
personnel. There should be no objects or obstacles in the swiveling range of the hoisting gear.
Cable holders
The electric power cables should be fastened properly to the pipeline with cable holders or other
suitable equipment. This should prevent loose hanging and damage to the electric power cables.
Depending on the cable length and weight, a cable holder should be fitted every two to three
meters.
Fixing materials and tools
Make sure you have the required tools (such as wrenches) and other material (such as plugs and
anchor bolts). The fastening materials should be sufficiently stable to ensure safe assembly.
Installation
The following information should be taken into consideration when installing the machine:
