7.3 Correct installation of the pump
- Ensure that the pump has not been damaged during
transportation or storage. Immediately report any damage to
the supplier.
- Ensure that all the packaging has been removed.
- Check that the information printed on the identification plate
corresponds with the order.
- Check the operating instructions in order to ensure that the
flow values, pressures & power consumption of the motor do
not exceed rated values.
- Ensure that the tube is suitable for the fluid to be conveyed
and that it is not damaged.
- Make sure that the temperature of the liquid does not exceed
the recommended temperature range.
- Ensure that there is enough space for free airflow around the
motor.
- Ensure that no nearby objects or direct sunshine radiate
additional heat to the motor.
7.3.1 Suction side
- The pump is to be positioned as near as possible to the liquid
container, so that the suction side is kept as short and straight
as possible.
- The suction line must be absolutely airtight and made of a
suitable material, so that it does not collapse under vacuum.
- The diameter must correspond to the rated diameter of the
tube. A larger diameter is recommended in the event of viscous
liquids.
- The pump is self-priming and does not require an admission
valve.
- The pump is reversible and the suction side can be connected
to either hydraulic connection of the pump. Normally
the option is selected which is best suited to the physical
conditions of the rest of the installation.
