!
WARNING
!
!
To drive the pump you must use one of the following compressed gases (called in this document "compressed air"):
- Compressed air supplied from air compressor
- Nitrogen (N
2
) gas
Use of compressed air other than the above may cause air pollution, damage to the pump, or even an explosion.
The maximum permissible pressure for the compressed air, and the fluid pumped by one of its pumps is 8 bars.
Should the above applicable maximum permissible pressure be exceeded, the following results may follow:
damage to the casing, or even a severe, possibly fatal accident.
In some pomp executions, specified by manufacturer, the max. pressure can reach 14 bars.
In case a diaphragm gets damaged, fluid will gush out together with air through the exhaust port. Provide
protective measures in consideration of possible leakage of fluid.
When you using the hose and pit etc, make sure to use a model with appropriate corrosion resistance for the fluid
to be pumped.
