- Shaft: Stainless Steel AISI 316, for maximum structural durability.
- Mechanical Seal: Made of Ceramic, Graphite and Stainless Steel, designed to withstand continuous workloads and various liquids.
Onboard Applications
The pump is extremely versatile and certified for the following uses:
- Fuel Transfer: Management and transfer of diesel between tanks.
- Water Management: Transfer of fresh water and seawater.
- Service Discharge: Emptying of grey water (kitchens and showers).
- Security: Bilge pumping and auxiliary fire-fighting uses.
Operational and Installation Advantages
Self-Priming Capacity: Thanks to the liquid ring star impeller, the CP 40 G boasts a self-priming capacity up to 8 vertical meters.
First Start-Up: It is necessary to fill the pump body with liquid only on first use or after long periods of inactivity. Subsequently, the pump self-primes even with the suction hose empty.
Practical Notes for the Installer:
- Filtration: It is strongly recommended to install a filter on the suction inlet to protect the impeller from solid debris.
- Check Valve: The use of a check valve is recommended to prevent water backflow and facilitate maintaining liquid in the pump body.
- Wiring: Make sure the power cables are adequate for the absorption of 45A to avoid voltage drops and overheating.
Warranty: 2 years (according to Gianneschi general sales conditions).
