Materials: because they matter

The use of bronze for pump body and impeller ensures resistance in seawater circuits and reliability in continuous operation.
The shaft in AISI 316 stainless steel offers excellent mechanical strength and corrosion resistance.

Typical applications

The CB 25/125A is suitable for professional onboard systems and technical circuits where effective water movement is required.

Recommended uses

• Seawater or freshwater circulation
• Seawater supply for onboard utilities and services
• Sanitary and air conditioning systems
• Pressure boosting and water systems
• Heating, cooling and recirculation
• Integration in autoclaves / hydrofor (according to plant configuration)

Integration into the system

The availability of threaded o flanged connections in the CB series allows the use of the pump in lines with different standards.
Before installation, it is recommended to check:

• compatibility with BSP or DN fittings,
• dimensions and overall size (315×170×200 mm),
• weight (16 kg),
• mounting position (the pump must be installed below the liquid level).

Operational advantages

• Materials suitable for seawater systems
• Reliable operation in continuous service
• Standardized and easily available components
• Good performance/consumption balance
• Possibility of catalog variants (open/closed impeller, different connections)

Use, notes, and recommendations

Before installation

• Check input voltage: 230 V – 50 Hz
• Check the type of connection required by the system (threaded/flanged)
• Ensure necessary space and accessibility for maintenance

During use

• Perform periodic checks in the presence of seawater
• Keep the circuit in conditions consistent with the declared performance
