Gianneschi CB 40/110 AIR centrifugal pump in bronze – 230 V, 50 Hz, 1Ph

For circulation and supply of fresh or seawater
Supplier code: 01CB40G102 – SKU: GIA000000003

The centrifugal pump Gianneschi CB 40/110 AIR is part of the series CB, a range designed for lifting and circulation of clean water, both fresh and seawater, in technical and onboard systems.
The construction in bronze and the declared metal components (impeller in bronze or special brass alloy, shaft in stainless steel AISI 316) make it a suitable solution for nautical contexts and systems requiring materials compatible with seawater.

This version is configured for power supply 230 V – 50 Hz – single-phase, with power 0.75 kW.

Features and construction details

Materials (data verified – CB series)

• Pump body: bronze
• Impeller: bronze / special brass alloy
• Shaft: AISI 316 stainless steel
• Mechanical seal: ceramic – graphite – stainless steel

The materials are indicated by the manufacturer for applications with fresh and seawater, and are a recurring choice in onboard systems.

Hydraulic configuration and connections

• Impeller: available in the CB series in configuration open or closed (depending on the version)
• Connections: the range includes versions BSP threaded and flanged DN
• Port sizes (CB range):
  • BSP threaded: from 1/2” to 1” 1/2
  • Flanged: from DN32 to DN65

These variants are part of the CB series and allow the pump to be integrated into existing systems or new installations.
(The exact configuration depends on the version)

Power supply

• Voltage: 230 V
• Frequency: 50 Hz
• Phase: 1Ph
• Power: 0.75 kW
• Motor: class F insulation – IP 44/55 protection (for AC versions)

These data allow verification of electrical compatibility with the onboard system or the technical system in which the pump is installed.

Typical applications (CB series – verified data)

The CB series is suitable for:

• Fresh or seawater circulation
• Seawater supply for onboard utilities
• Sanitary systems
• Air conditioning systems
• Pressure boosting in water systems
• Heating, cooling and circulation systems
• Integration in autoclave / hydrofor systems

The pump is not self-priming: the manufacturer specifies that it must be installed below the liquid level, to prevent the pump body from emptying.

Operational advantages

Materials suitable for marine use

The choice of bronze and AISI 316 stainless steel meets the needs of systems that handle seawater, contributing to greater reliability over time.

Integration flexibility

The CB series offers variants with different impellers and connections (threaded or flanged), allowing adaptation to existing systems or layouts with limited space.

Technical solution for onboard systems

The CB 40/110 AIR is positioned as a circulation / water supply pump in nautical and technical systems, with clear electrical specifications and materials compatible with fresh or seawater.

Use, installation and notes

Recommended checks before purchase

• Confirm the model code: 01CB40G102
• Check the type of connection request (threaded or flanged)
• Compare the size of the ports with the system standard (BSP or DN)
• Check the electrical consistency: 230 V – 50 Hz – 1Ph

General installation guidelines

For onboard systems, it is advisable to provide accessible mounting for maintenance and the adoption of shut-off valves to facilitate future operations.
Commissioning procedures must always follow the manufacturer's instructions.
