Startup
The "Startup" chapter contains all the important instructions for the operating personnel for start-
ing up and operating the machine safely.
The following specifications must be adhered to and checked:
- Type of installation
- Operating mode
- Minimum water coverage / max. submersion
If the machine has not been operated for some time, check these speci-
fications again and rectify any faults you find.
The operation and maintenance handbook must always be kept either by
the machine or in a place specially reserved for it where it is accessible
for operating personnel at all times.
In order to prevent damage or serious injury during startup of the machine, the following points
must be observed:
The machine may only be started up by qualified personnel. The safety
advice must be followed at all times.
- Every person working on the machine must have received, read and understood this operat-
ing and maintenance manual. This must also be confirmed with a signature in the machine
operator list.
- Activate all safety devices and emergency stop elements before startup.
- Electrical and mechanical settings may only be made by specialists.
- This machine may only be used under the working conditions specified in this handbook.
Preparatory measures
The machine has been designed and constructed using the very latest technology. Under normal
working conditions it will operate reliably and for long periods. The one condition for this is that all
instructions and advice are observed.
Minor oil leakage in the mechanical shaft seal on delivery is no cause for concern. However, it must
be removed prior to submersion in the pumped liquid.
Please check the following:
- Cable guidance – no loops, slightly taut
- Check the temperature and submersion depth of the pumped liquid – see machine data sheet
- If a hose is used on the discharge side, it should be flushed out with clean water before use to
prevent any sediment causing blockages
- The pump sump must be cleaned for wet installation
- Clean the discharge and intake side pipe system and open all sliders
- The pump housing must be flooded, i.e. it should be completely full of fluid, with no air in it at
all. Bleeding can take place using a suitable bleeding device in the system, or, if available, with
bleeder screws on the discharge port.
- Check that all accessories, the pipe system and suspension unit are properly fitted
- Check all level control and dry-run protection systems
An insulation test and filling level check must be carried out prior to
start-up, as described in chapter 7.
Electrical system
Observe the relevant local and national regulations when laying out and selecting the electric lines
as well as when connecting the motor. The motor must be protected by a motor protection switch.
Have the motor connected in accordance with the "Electrical connection" data sheet. Pay attention
to the direction of rotation. If the direction of rotation is incorrect, the machine will not perform as
specified, and under certain circumstances, can become damaged. In accordance with the machine
