Operating instruccions Peristaltic Pumps
- 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
- Install a manometer in the pressure line if the back-pressure value is unknown.
Maximum pressure on suction/inlet side is 0,5 bar (7,25 psi approx.).
- 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.
7.3.2.
Discharge side
- The discharge line is to be kept as straight and short as possible, in order to avoid
performance reduction.
- The diameter must correspond to the rated diameter of the tube. A larger diameter
is recommended in the event of viscous liquids.
- Do not close or block the outlet since, as it is a volumetric pump, it would cause
the tube to break or an electro-mechanical overload.
