Self-priming capacity
The CP series, thanks to the liquid ring operation and star impeller, offers a remarkable self-priming capacity (up to 8 m vertical according to the standard technical datasheet).
Only at the first start-up or after a long period of inactivity is it necessary to fill the pump body.
Typical applications
The CP 30 A1 G is commonly used in nautical and plant engineering for:
- Diesel transfer
- Liquid handling (fresh and seawater)
- Grey water discharge (showers, kitchen) – for series A1/A2
- Bilge pumping
- Onboard systems requiring self-priming pumps
Installation and recommendations
- It is recommended to install a filter and a non-return valve (check valve) on the suction line to prevent backflow.
- Check the compatibility liquid compatibility with the pump materials.
- For power supply 230V, ensure connection through appropriate electrical protections.
- Periodically check the mechanical seal and the condition of the pipes, especially in marine environments.
